The advantage of using investment banks to handle an IPO is that they have the necessary expertise as well as relationships with potential investors. However, some issuers feel that they would prefer for the market to decide the right price for their company.

One way they can do this is through a Dutch auction. This is a procedure where all investors (not just clients of an investment bank) are invited to submit bids indicating how many shares they would like to purchase and at what price.

Question 15

Q

what is deposit insurance?

Answer

A

To maintain confidence in the banking system, many countries have introduced deposit insurance. This typically provides a certain amount of protection to a depositor against losses arising from a bank failure.

Deposit insurance is a measure implemented in many countries to protect bank depositors, in full or in part, from losses caused by a bank’s inability to pay its debts when due. Deposit insurance systems are one component of a financial system safety net that promotes financial stability.

Question 16

Q

what is regulatory Capital

Answer

A

Regulatory capital is the minimum capital that regulators require banks to keep.

Question 17

Q

what is Economic capital

Answer

A

Economic capital is a bank’s own estimate of the capital it requires.

Question 18

Q

what is the same area and different aspect between regulatory capital and economic capital

Answer

A

common area:
In both cases, capital can be thought of as funds that are available to absorb unexpected losses.

different aspect:
A com-mon objective in calculating economic capital is to maintain a high credit rating (as will be described in later chapters). Economic capital is allocated to a bank’s business units so that they can be compared using a return on allocated economic capital metric.

Question 19

Q

The amount of capital that is necessary depends on:

Answer

A

the size of possible losses.

Question 20

Q

Potential conflict mentions_______

Answer

A

advisor-seller problem, dump garbage, information leakage, research independent problem

Question 21

Q

the solution for information leakage and research independent problem is______

Answer

A

Chinese Wall

Question 22

Q

what is Chinese wall

Answer

A

Chinese wall is a business term describing an information barrier within an organization that was erected to prevent exchanges or communication that could lead to conflicts of interest. For example, a Chinese wall may be erected to separate and isolate people who make investments from those who are privy to confidential information that could improperly influence the investment decisions. Firms are generally required by law to safeguard insider information and ensure that improper trading does not occur.

For finance, A Chinese wall is most commonly employed in investment banks, between the corporate-advisory area and the brokering department in order to separate those giving corporate advice on takeovers from those advising clients about buying shares;[1] see #Research there. The “wall” is thrown up to prevent leaks of corporate inside information, which could influence the advice given to clients making investments, and allow staff to take advantage of facts that are not yet known to the general public.

For insurance, The term is used in property and casualty insurance to describe the separation of claim handling where both parties to a claim (e.g. an airport and an airline) have insurance policies with the same insurer. The claim handling process needs to be segregated within the organisation to avoid a conflict of interest.

Question 23

Q

what is information leakage

Answer

A

Capital that exits an economy or system rather than remaining within the system is leakage.
Funds spent on taxes, deposited into savings, or used to buy imported goods will create leakage.
Export funds can result in leakage when those funds are invested in areas other than where the exports are produced

Information or data leakage occurs when internal information that should be held private or confidential is released to the public. This release of information can include the accidental or intentional disclosure of information, or a failure to secure the information, which leads to exposure.

Question 24

Q

what is Originate-to-distribute model

Answer

A

Traditionally, banks have originated loans and kept them on their balance sheet. An alternative to this is what has become known as the originate-to-distribute model. Under this model, banks use their expertise to originate loans and then sell them (directly or indirectly) to investors.

Question 25

Q

Originate-to-distribute arrangements have been used in the U.S. mortgage market for many years. The U.S. government has sponsored the creation of three entities:

Answer

A

Government National Mortgage Association (GNMA) or Ginnie Mae,
Federal National Mortgage Association (FNMA) or Fannie Mae, and
Federal Home Loan Mortgage Corporation (FHLMC) or Freddie Mac.

Question 26

Q

The originate-to-distribute model played a role in the 2007–2008 crisis, because____

Answer

A

Banks relaxed their mortgage lending standards so that the quality of the mortgages being originated declined. Despite this decline in quality, however, banks still managed to securitize them. In fact, they re-securitized mortgages by creating tranches from tranches. As defaults on the mortgages grew higher, losses were experienced by tranche holders. Unsurprisingly, for a period after the crisis, the originate-to-distribute model could not be used because it was not trusted by investors.

Question 27

Q

Process of the originate-to-distribute model _______

Answer

A

Originator provide loan for borrower and receive asset. Originator exchange cash by SPV. SPV receive investors’ Cash and output ABS to investor.

Question 28

Q

what is ABS

Answer

A

An asset-backed security (ABS) is an investment security—a bond or note—which is collateralized by a pool of assets, such as loans, leases, credit card debt, royalties, or receivables. … For investors, asset-backed securities can be an alternative to corporate debt

Question 29

Q

Securitized Asset from______

Answer

A

Student loans and Credit card receivable

Question 30

Q

E.g. for SPV

Answer

A

House holder (Borrower) applies for bank's Mortgage and bank receives house holder's loan.
Bank sell loans to GNMA, FNMA, FHLMC (or other originators or lenders) and bank receive cash from them. GNMA, FNMA, FHLMC issues MBS to investor.

Question 31

Q

what is MBS

Answer

A

A mortgage-backed security (MBS) is an investment similar to a bond that is made up of a bundle of home loans bought from the banks that issued them. Investors in MBS receive periodic payments similar to bond coupon payments. … An MBS may also be called a mortgage-related security or a mortgage pass-through.

Equity funds are the most popular type of mutual funds. They can be subdivided into:
• Actively managed funds, and • Index funds.

ETF (Exchange-traded funds (ETFs) ): 开放式指数证券基金, 开放式基金的一种，交易和封闭式基金类似

NAV = (funds assets-funds liabilities)/total share outstanding

NAV could only be calculated after the close of the trading days (for open-end funds)

NAV could only be calculated continuously during the time of trading (close-end fund and ETFs)

Question 50

Q

hedge funds

Answer

A

hedge fund strategies (7):
Long/short equity
dedicated short 
distressed securities 
merger/fixed income/convertible arbitrage
emerging markets 
Global Macro
managed future

Question 51

Q

Funds from different clients are pooled, and the fund managers choose investments in accordance with stated invest-ment goals and risk appetites. There are several advantages to this approach:

Answer

A

Fund managers may have more investment expertise than their clients.
Transaction costs (as a percentage of the amount traded) are usually lower for large trades than for small trades.
It is difficult for a small investor to be well diversified, but a large fund with billions of dollars should not have any difficulty in achieving diversification

Question 52

Q

Despite these safeguards, there have been instances of undesirable behavior:

Answer

A

a) Late Trading. As mentioned, all trades to buy and sell shares in an open-end mutual fund are at 4 p.m., and thus trade instructions should reach a broker before 4 p.m.
b) Market Timing. Not all the assets of an open-end mutual fund trade actively. This may lead to the prices used to calculate NAV being stale (i.e., not reflecting recent information).
c) Front Running. If a trader working for a mutual fund (or any other type of fund) knows that the fund will execute a big trade that is likely to move the market, it is tempting for the trader to trade on his or her own account immediately before putting through the fund’s trade.
d) Directed Brokerage. This involves an informal arrangement between a mutual fund and a brokerage house. The unwritten agreement is that the mutual fund will use the brokerage house for its trades if the brokerage house recommends the mutual fund to its clients.

Question 53

Q

While mutual funds and ETFs cater to the needs of small investors, hedge funds usually accept only large investments from wealthy private individuals or institutions. There are several other differences. The following are examples.

Answer

A

A mutual fund or ETF allows investors to redeem their shares on any day. A hedge fund may have a lock-up period during which time funds cannot be withdrawn. Lock-up periods of one year are common.
The NAV of a mutual fund or ETF must be calculated and reported at least once a day. In contrast, hedge funds have no such requirements, and their NAVs are reported much less frequently.
Mutual funds and ETFs must disclose their investment strategies. Hedge funds generally follow proprietary strategies that they see as fundamental to their competitiveness and/or value proposition. They give prospective clients some information to explain their value proposition, but do not disclose everything. Furthermore, they are not obligated to stick to one strategy.
Mutual funds and ETFs may be restricted in their use of leverage. A hedge fund is only restricted by the amount banks are willing to lend to it.
Hedge funds charge an incentive fee as well as a management fee. A typical hedge fund fee is 2 plus 20%. This means that the investors are charged 2% of the value of their investment per year along with 20% of the profits (if these net profits are positive).11

Question 54

Q

The descriptor hedge fund arises from the long-short strategies followed by many hedge funds.

Answer

A

This type of strategy involves taking long positions in stocks expected to provide good returns and short positions in stocks expected to provide poor returns. However, there are also hedge fund strategies that involve little to no hedging whatsoever

Question 55

Q

hedge fund performance measurement bias

Answer

A

survivorship bias: overestimated return of industry
backfill bias: backfill only good strategies
stale price bias: underestimate volatility
self-selection bias: only good players choose to report

计算： management fee, incentive fee
Hedge funds charge an incentive fee as well as a management fee. A typical hedge fund fee is 2 plus 20%. This means that the investors are charged 2% of the value of their investment per year along with 20% of the profits (if these net profits are positive).

Question 56

Q

A long-short fund’s performance should depend entirely on the fund manager’s ability to pick winners and losers (and not on what happens to the market as a whole) so long as:

Answer

A

The value of the shares shorted equals the value of those bought, and
Both the long and short portfolios have the same sensitivity to market movements.

Question 57

Q

Dedicated Short

Answer

A

At any given time, it is reasonable to suppose that there are as many overvalued shares as undervalued shares. A dedicated short fund devotes its attention to picking overvalued stocks. Hedge funds using dedicated short strategies look for companies that are experiencing difficulties not recognized by the market. However, they are not hedged against the overall performance of the market. It is therefore not surprising that dedicated short strategies perform badly during bull markets.

Question 58

Q

Distressed Debt

Answer

A

Some hedge funds specialize in trading distressed debt. They use their understanding of the bankruptcy process to find situations where they can take a big position in the debt and benefit from reorganization proposals.

Question 59

Q

Merger Arbitrage

Answer

A

When a company announces that it is prepared to buy another company, there is usually some uncertainty about whether the acquisition will proceed. The share price of the target company usually increases, but not to the price being offered. A merger arbitrage hedge fund might consider that there is an 80% chance that the acquisition will be successful and that the acquisition price will be higher than the current price. Buying the target company’s shares could then be a good trade. If the offer on the table is a share-for-share exchange and the hedge fund expects an improvement in the terms before a deal is finally announced, it could buy the shares in the target company and sell shares in the acquiring company in a ratio that reflects the current offer.

It should be emphasized that merger arbitrage is not about trading on inside (non-public) information (which is illegal).16 It is about assessing the probability of a merger being successful and the likely final price (or exchange ratio in the case of a share-for-share exchange) at the time of the merger announcement.

Question 60

Q

Convertible Arbitrage

Answer

A

Convertible bonds are bonds issued by a company that can be converted into a predetermined number of the company’s shares at a future time. Convertible arbitrage hedge funds use sophisticated models to value convertible bonds. They hedge the risks associated with the company’s share price, credit spreads, and interest rates. If the market price is currently different from the hedge fund’s model price, the strategy can be profitable if the market price converges to the model price.

Question 61

Q

Fixed-Income Arbitrage

Answer

A

At any given time, some traded bonds are likely to be relatively expensive compared with other similar bonds, while others are relatively cheap. In a fixed-income arbitrage strategy, the hedge fund manager buys bonds that seem relatively cheap and shorts the ones that are relatively expensive. Typically, they use a lot of leverage to make the strategy worthwhile.

Question 62

Q

Emerging Markets

Answer

A

Hedge funds that specialize in emerging markets attempt to gather information about little-known equity securities in developing countries. When they consider a security to be under-valued (overvalued), they buy (short) it in the local markets. An alternative is to use American Depositary Receipts (ADRs), which are certificates backed by shares of a foreign company and traded on an exchange in the U.S. Any discrepancies between ADR prices and local prices can give rise to arbitrage opportunities.
Hedge funds can also invest in emerging market sovereign debt. However, this is fraught with risks. Countries such as Russia, Argentina, Brazil, and Venezuela have defaulted multiple times (as will be discussed in Chapter 5 of Valuation and Risk Models).

Question 63

Q

Global Macro

Answer

A

Global macro hedge funds use macroeconomic analysis to determine their trades. Specifically, they look for situations where markets are not in equilibrium using models based on factors such as exchange rates, interest rates, balance of payments, inflation rates, etc. Sometimes the results are spectacular: The Quantum Fund managed by George Soros made a profit of USD 1 billion in 1992 by betting that the British pound was overvalued. However, not all global macro trades are that successful, and economies can remain in disequilibrium for long periods of time.

Question 64

Q

Managed Futures

Answer

A

Managed futures strategies attempt to predict future commodity prices and take positions that will be profitable if the predictions are correct. Several different models are used and trading rules are usually back-tested by seeing how well they would have performed if they had been used in the past. However, there is a danger in this. Back-testing does not differentiate between strategies with a fundamental understanding of the markets and strategies that were just lucky (and thus not necessarily bound to be successful in the future)

A

spot rate valuation method

The spot rate is calculated by finding the discount rate that makes the present value (PV) of a zero-coupon bond equal to its price. These are based on future interest rate assumptions. So, spot rates can use different interest rates for different years until maturity.

Bootstrapping spot rate — bootstrapping

Bootstrapping spot rates using the par curve is a very important method that allows investors to derive zero coupon interest rates from the par rate curve. Bootstrapping the zero coupon yield curve is a step-by-step process that yields the spot rates in a sequential way.

Answer 75

A

RF = (R2T2 - R2T2) / (T2 - T1)

= R2 + (R2 - R1)* T1/(T2 - T1)

Answer 76

A

pure expectation theory

A theory that asserts that forward rates exclusively represent the expected future rates. In other words, the entire term structure reflects the market’s expectations of future short-term rates. For example, an increasing slope to the term structure implies increasing short-term interest rates

liquidity preference (premium) theory

Liquidity preference theory suggests that investors demand progressively higher premiums on medium and long-term securities as opposed to short-term securities.

market segmentation theory

Market segmentation theory states that long- and short-term interest rates are not related to each other because they have different investors.
Related to the market segmentation theory is the preferred habitat theory, which states that investors prefer to remain in their own bond maturity range due to guaranteed yields. Any shift to a different maturity range is perceived as risky.

Answer 77

A

What Is a Forward Rate Agreement – FRA?

Forward rate agreements (FRA) are over-the-counter contracts between parties that determine the rate of interest to be paid on an agreed upon date in the future. An FRA is an agreement to exchange an interest rate commitment on a notional amount.

Answer 78

A

Macaulay duration
MacDur = the sum of (t x PVCFt) / the sum of (PVCFt)
perpetuity bond, MacDur = (1 +r)/r
The Macaulay duration is the weighted average term to maturity of the cash flows from a bond. The weight of each cash flow is determined by dividing the present value of the cash flow by the price. Macaulay duration is frequently used by portfolio managers who use an immunization strategy.

Macaulay Duration= the sum of [t = 1 to n] {(t x c)/(1 + y)^t + (n x M)/(1+y)^n}/current bond price

t=respective time period
C=periodic coupon payment
y=periodic yield
n=total number of periods
M=maturity value
Current Bond Price=present value of cash flows

modified duration
ModDur = MacDur / (1+r) r 是期间利率
% delta price =~~ -ModDur x delta Yield
Modified duration is a formula that expresses the measurable change in the value of a security in response to a change in interest rates. Modified duration follows the concept that interest rates and bond prices move in opposite directions. This formula is used to determine the effect that a 100-basis-point (1 percent) change in interest rates will have on the price of a bond.
Modified Duration= Macauley Duration/ 1 + YTM/n
Macauley Duration=weighted average term to
maturity of the cash flows from a bond
YTM=yield to maturity
n=number of coupon periods per year
money duration / dollar duration:
MoneyDur = Mod x Price(full)

money duration is called dollar duration. It is the approximate dollar change in a bond’s price for a 100 basis point change in yield. It is the approximate dollar change in a bond’s price for a 100 basis point change in yield.
The dollar duration measures the dollar change in a bond’s value to a change in the market interest rate. The dollar duration is used by professional bond fund managers as a way of approximating the portfolio’s interest rate risk. Dollar duration is one of the several different measurements of bond duration.
As duration measures the sensitivity of a bonds price in interest rate changes, dollar duration seeks to give these changes an actual dollar amount.

DVO1(a.k.a. PVBP):
PVBP = (P_ - P+)/2 P_是YTM上升1bp的价格， P+ 是YPM 下降1bp的价格

Price value of a basis point (PVBP) is a measure used to describe how a basis point change in yield affects the price of a bond.
Price value of a basis point is also known as the value of a basis point (VBP), dollar value of a basis point (DVBP), or basis point value (BPV).

Answer 79

A

Convexity is a measure of the curvature, or the degree of the curve, in the relationship between bond prices and bond yields. Convexity demonstrates how the duration of a bond changes as the interest rate changes. Portfolio managers will use convexity as a risk-management tool, to measure and manage the portfolio’s exposure to interest rate risk.

凸度是衡量债券价格和债券收益率之间关系的曲率或曲线的程度。凸度说明了债券的期限如何随利率的变化而变化。投资组合经理将使用凸度作为风险管理工具，以衡量和管理投资组合面临的利率风险。

KEY TAKEAWAYS
Convexity is a risk-management tool, used to measure and manage a portfolio’s exposure to market risk.
Convexity is a measure of the curvature in the relationship between bond prices and bond yields.
Convexity demonstrates how the duration of a bond changes as the interest rate changes.
If a bond’s duration increases as yields increase, the bond is said to have negative convexity.
If a bond’s duration rises and yields fall, the bond is said to have positive convexity.

Bond duration measures the change in a bond’s price when interest rates fluctuate. If the duration of a bond is high, it means the bond’s price will move to a greater degree in the opposite direction of interest rates. Conversely, when this figure is low the debt instrument will show less movement.

Typically, if market rates rise by 1%, a one-year maturity bond price should decline by an equal 1%. However, for bonds with long-dated maturities, the reaction increases. In other words, if rates rise by 1%, bond prices fall by 1% for each year of maturity. For example, if rates rise by 1%, the two-year bond price would fall 2%, the three-year bond price by 3%, and the 10-year price by 10%.

债券期限是衡量利率波动时债券价格的变化。如果债券的期限很高，则意味着债券的价格将在与利率相反的方向上更大程度地波动。相反，当该数字较低时，债务工具将显示较少的变动。

通常，如果市场利率上升1％，则一年期债券价格应下降相等的1％。但是，对于期限长的债券，反应会增加。换句话说，如果利率上升1％，则到期的每一年债券价格都会下降1％。例如，如果利率上升1％，则两年期债券价格将下降2％，三年期债券价格将下降3％，十年期价格将下降10％。

% delta price full =~~ [-ModDur x delta] x [0.5 x Con x Yield^2]

A

day count convention:
US. treasury bond: actual /actual
US. corporate and municipal bond: 30/360
US. money market instruments (Treasury bills: actual / 360)

A day-count convention is a standardized methodology for calculating the number of days between two dates.
The interest on most money market deposits and floating-rate notes is calculated on an actual/360 day-count convention while bonds and notes issued by the U.S. Treasury earn interest calculated on an actual/actual basis..
The fixed-rate leg of an interest rate swap and most fixed-rate bonds use either the 30/360 or 30/365 day-count convention while the floating-rate leg uses some variation of an actual/360 or 365 day-count convention.

30 / 360 - calculates the daily interest using a 360 day year and then multiplies that by 30 (standardized month)
30 / 365 - calculates the daily interest using a 365 day year and then multiplies that by 30 (standardized month)
actual / 360 - calculates the daily interest using a 360 day year and then multiplies that by actual number of days in each time period.
actual / 365 - calculates the daily interest using a 365 day year and then multiplies that by actual number of days in each time period.
actual / actual - calculates the daily interest using the actual number of days in the year and then multiplies that by actual actual number of days in each time period.

quotations for T-bill:
quoted price = 360/n * (100 - Y)
Y is cash price

Maturity (sometimes shown as “issue”): This is the date the bill will be redeemed and the investor paid the face value amount. For purposes of this example, assume the maturity date is 100 days in the future.
Bid: The bid represents the interest rate the buyer wants to be paid. Converting the bid into an actual price requires a bit of work. The process involves multiplying the bid (dropping the decimals) by the number of days until maturity and then dividing by 360 and then subtracting that number from 10,000.
4100/360=$1.11
$10,000-$1.11=$9,998.89
In this example, the buyer is willing to pay $9,998.89 for a bill that will be redeemed for $10,000 in 100 days.
Ask: The ask represents the interest rate the seller is willing to pay. The equation to determine the asking price is the same as that used to determine the bid. Simply replace the asking price with the bid price in the equation.
3100/360=$0.83
$10,000-$0.83=$9,999.17
In this example, the seller is willing to accept $9,999.17 for a bill that will be redeemed for $10,000 in 100 days.
Change: The change shows the difference from the prior bid. In this case, the prior bid was higher by 0.01 basis points.
Yield: The yield is the annualized rate of return if held until maturity based on the asking price. In this example, the yield is 0.03.

quotation for T-bond

a. dollars and thirty-seconds(32) of a dollar with a face value of $100
b. Full price = Clean price + Accrued interest
c. accrued interest: accrued interest = # of days from coupon to the settlement date / # of days in coupon period

A bond quote refers to the last price at which a bond traded.
Bond quotes are expressed as a percentage of par (face value) and converted to a point scale.
The par value is traditionally set at 100, which represents 100% of a bond’s $1,000 face value.
Bond quotes may also be expressed as fractions.

Answer 81

A

a. conversion factor
b. short position choose to delivery any government bond
c. face value is 100000 USD
d. cheapest-to-deliver bond
1. revenue for short position: QFP x CF + AI
2. cost for short position: QBP + AI
3. CTD is the on that minimizes: QBP - (QFP x CF)

QFP = quoted futures price/settlement price

CF = conversion factor

AI = accrued interest since the last coupon date on the bond delivered

Bond Conversion Factors
The bonds that can be delivered are standardized through a system of conversion factors calculated according to the rules of the exchange. The conversion factor is used to equalize coupon and accrued interest differences of all delivery bonds. The accrued interest is the interest that’s accumulated and yet to be paid.
债券转换因子
通过根据交换规则计算的转换因子系统，可以对可交割的债券进行标准化。转换因子用于均衡所有交付债券的息票和应计利息差额。应计利息是已累计但尚未支付的利息。

What Is Accrued Interest?
In accounting, accrued interest refers to the amount of interest that has been incurred, as of a specific date, on a loan or other financial obligation but has not yet been paid out. Accrued interest can either be in the form of accrued interest revenue, for the lender, or accrued interest expense, for the borrower.
什么是应计利息？
在会计中，应计利息是指截至特定日期已就贷款或其他财务义务产生但尚未支付的利息金额。应计利息可以是贷方应计利息收入的形式，也可以是借款人应计利息费用的形式。

Accrued interest is a feature of accrual accounting, and it follows the guidelines of the revenue recognition and matching principles of accounting.
Accrued interest is booked at the end of an accounting period as an adjusting journal entry, which reverses the first day of the following period.
The amount of accrued interest to be recorded is the accumulated interest that has yet to be paid as of the end date of an accounting period.

What Does Cheapest to Deliver Mean?
The term cheapest to deliver (CTD) refers to the cheapest security that can be delivered in a futures contract to a long position to satisfy the contract specifications. It is relevant only for contracts that allow a variety of slightly different securities to be delivered. This is common in Treasury bond futures contracts, which typically specify that any treasury bond can be delivered so long as it is within a certain maturity range and has a certain coupon rate. The coupon rate is the rate of interest a bond issuer pays for the entire term of the security.

最便宜的交付意味着什么？
术语“最便宜的交割”（CTD）是指可以在期货合约中交割以满足合约规格的多头头寸的最便宜的证券。它仅与允许交付各种略有不同的证券的合同有关。这在国债期货合约中很常见，通常规定只要在一定期限内并且具有一定的票面利率，就可以交付任何国债。息票利率是债券发行人在整个证券期限内支付的利率。

CTD = Current Bond Price – Settlement Price x Conversion Factor

Not to be confused with the euro/U.S. dollar (EUR/USD) currency pair or the euro currency, eurodollars are a type of U.S. dollar deposit held in a bank outside of the United States.
The name eurodollars stems from the fact that the term initially referred to dollar-denominated deposits largely held in European banks, but now dollar deposits are held in a variety of banks across the globe.
Eurodollars typically offer higher yields because they are not subject to U.S. bank regulation and therefore carry greater risk.
Eurodollar futures trade on the trading floor and electronically on the Chicago Mercantile Exchange.
不要与欧元/美国混淆美元（EUR / USD）货币对或欧元货币，欧元是在美国以外的银行中持有的美元存款的一种。
欧洲美元之所以得名，是因为该术语最初指的是主要在欧洲银行中持有的以美元计价的存款，但现在美元存款则在全球的多家银行中持有。
欧洲美元通常会提供更高的收益率，因为它们不受美国银行监管的约束，因此风险更大。

LIBOR and Eurodollars
The price of eurodollar futures reflects the interest rate offered on U.S. dollar-denominated deposits held in banks outside the United States. More specifically, the price reflects the market gauge of the 3-month U.S. dollar LIBOR (London Interbank Offered Rate) interest rate anticipated on the settlement date of the contract. LIBOR is a benchmark for short-term interest rates at which banks can borrow funds in the London interbank market. Eurodollar futures are a LIBOR-based derivative, reflecting the London Interbank Offered Rate for a 3-month $1 million offshore deposit.

Eurodollar futures prices are expressed numerically using 100 minus the implied 3-month U.S. dollar LIBOR interest rate. In this way, a eurodollar futures price of $96.00 reflects an implied settlement interest rate of 4%, or 100 minus 96. Price moves inverse to yield.

For example, if an investor buys one eurodollar futures contract at $96.00 and the price rises to $96.02, this corresponds to a lower implied settlement of LIBOR at 3.98%. The buyer of the futures contract will have made $50. (1 basis point, 0.01, is equal to $25 per contract, then a move of 0.02 equals a change of $50 per contract.)
LIBOR和欧洲美元
欧元兑美元期货的价格反映了在美国以外银行持有的以美元计价的存款所提供的利率。更具体地说，该价格反映了在合同结算日预期的3个月美元伦敦银行同业拆借利率（LIBOR）的市场价格。 LIBOR是银行可以在伦敦银行间市场借贷资金的短期利率基准。欧洲美元期货是一种基于伦敦银行同业拆借利率的衍生产品，反映了伦敦银行同业拆借利率，为期三个月的100万美元离岸存款。

欧洲美元期货价格以100减去隐含的3个月美元LIBOR利率的数字表示。这样，96.00美元的欧洲美元期货价格反映了4％（即100减去96）的隐含结算利率。价格与收益率成反比。

例如，如果投资者以96.00美元的价格购买一份欧元美元的期货合约，并且价格上涨至96.02美元，则对应于伦敦银行同业拆借利率的隐含结算价较低，为3.98％。期货合约的买主将获得$ 50。（1个基点0.01，等于每张合约$ 25，然后移动0.02等于每张合约变动$ 50。）
Hedging with Eurodollar Futures
Eurodollar futures provide an effective means for companies and banks to secure an interest rate for money it plans to borrow or lend in the future. The eurodollar contract is used to hedge against yield curve changes over multiple years into the future.

For example, say a company knows in September that it will need to borrow $8 million in December to make a purchase. Recall that each eurodollar futures contract represents a $1 million time deposit with a three-month maturity. The company can hedge against an adverse move in interest rates during that three-month period by short selling eight December eurodollar futures contracts, representing the $8 million needed for the purchase.

The price of eurodollar futures reflects the anticipated London Interbank Offered Rate (LIBOR) at the time of settlement or, in this case, December. By short selling the December contract, the company profits from upward movement in interest rates, reflected in correspondingly lower December eurodollar futures prices.

Let’s assume that on Sept. 1, the December eurodollar futures contract price was exactly $96.00, implying an interest rate of 4.0%, and at the expiry in December, the final closing price is $95.00, reflecting a higher interest rate of 5.0%. If the company had sold eight December eurodollar contracts at $96.00 in September, it would have profited by 100 basis points (100 x $25 = $2,500) on eight contracts, equaling $20,000 ($2,500 x 8) when it covered the short position.

In this way, the company was able to offset the rise in interest rates, effectively locking in the anticipated LIBOR for December as it was reflected in the price of the December eurodollar contract at the time it made the short sale in September.

The “crack” is an industry term for breaking apart crude oil into the component finished products, including gases like propane, heating fuel, gasoline, light distillates, intermediate distillates, and heavy distillates.
2. A crush spread is used to hedge the margin between soybean futures and soybean oil and meal futures. With this strategy, a trader takes a long position on soybean futures and a short position on soybean oil and meal futures. The trader may also take the opposite side of this options spread.
3. The spark spread uses natural gas as the raw material component and electricity as the finished product. It is a standard metric for estimating the profitability of natural gas-fired electric generator. For coal, the difference is called the dark spread.

What Is an Order?

An order is a set of instructions to a broker to buy or sell an asset on a trader’s behalf.
There are multiple order types which will affect what price the investor buys or sells at, when they will buy or sell, or if their order will be filled or not.
Which order type to use depends on the trader’s outlook for the asset, whether they want to get in and out quickly, and/or how concerned they are about the price they get.

Here are some the basic order types:
1. A market order instructs the brokerage to complete the order at the next available price. Market orders have no specific price and are generally always executed unless there is no trading liquidity. Market orders are typically used if the trader wants in or out of a trade quickly and is not concerned about the price they get.
2. A limit buy order instructs the brokerage to buy a security at or below a specified price. Limit orders ensure that a buyer pays only a specific price to purchase a security. Limit orders can remain in effect until they are executed, expire, or are canceled.
3. A limit sell order instructs the broker to sell the asset at a price which is above the current price. For long positions, this order type is used to take profits when the price has moved higher after buying.
4. A sell stop order instructs the brokerage to sell if an asset reaches a specified price below the current price. A stop order can be a market order meaning it takes any price once triggered, or it can be a stop limit order where it can only execute within a certain price range (limit) after being triggered.
5. A buy stop order instructs the broker to buy an asset when it reaches a specified price above the current price.
6. A day order must be executed during the same trading day that the order is placed.
Good till canceled (GTC) orders remain in effect until they are filled or canceled.
7. If an order is not a day order or a good til canceled order, the trader typically sets an expiry for the order.
Immediate or cancel (IOC) means that the order only remain active for a very short period of time, such as several seconds.
8. An all or none (AON) order specifies that the entire size of the order be filled, an partial fills will not be accepted.
9. A fill or kill (FOK) order must be completed immediately and completely or not at all and combines an AON order with an IOC order.

Closeout

This is the case where the futures trader closes out the futures contract even before the expiry. A trader who has a long position can take an equivalent short position in the same contract, and both the positions will be offset against each other. Similarly, a trader with a short position can take a long position in the same contract to closeout the position.

Delivery

On the settlement date, the short can settle the contract by delivering the underlying asset to the long. The contract is settled by delivery. This method is hardly used and constitutes not more than 1% of contract settlements.

In case of the physical delivery, the clearinghouse will select a counterparty for physical settlement (accept delivery) of the futures contract. Typically the counterparty selected will be the one with the oldest long position.

Cash Settlement

Cash settlement can be done only if the contract specifies so. The trader just leaves his position open and when the contract expires, his margin account will be marked-to market for P&L on the final day of the contract. This is the most commonly used method as the trader saves on the transaction costs of closing out the position.
只有在合同中明确规定，才可以进行现金结算。交易者只是开仓，合约到期时，其保证金账户将在合约的最后一天被标记为损益表。这是最常用的方法，因为交易者节省了平仓的交易成本。

Exchange for Physicals

A contract can also be terminated through an exchange of physicals. In this case, a trader finds another trader who has an opposite position in the same futures contract and delivers the underlying assets to him. This happens outside the exchange floor, and is called an ex-pit transaction. The traders will then inform the clearinghouse about the transaction.

Contango is when the futures price is above the expected future spot price. A contango market is often confused with a normal futures curve.
Normal backwardation is when the futures price is below the expected future spot price. A normal backwardation market is often confused with an inverted futures curve.
A futures market is normal if futures prices are higher at longer maturities and inverted if futures prices are lower at distant maturities.

Contango
A contango market is often confused with a normal futures curve.

character of futures contracts
convergence of futures and spot prices
backwardation:
sport price > future price to sport price = future price
contango:
sport price < future price to sport price = future price

two results of hedging 
perfect hedging:
exactly offset any gains or losses from an existing investment position
without perfect hedging 
basis risk:
spot price - future price 
reasons:
different asset 
different maturity 
closing out before delivery month 
two kinds of imperfect hedging:
close hedging (different underlying)
stack and roll (facing rollover basis risk)

calculation
1. optimal hedge ratio
The optimal hedge ratio or minimum variance hedge ratio is a concept that defines the degree of correlation between an asset or liability and the financial product (normally a futures contract) purchased to hedge financial risks.

h* quantifies the systematic comovement between 2 asset, minimize the portfolio most, can be calculated based on the standard deviation of both the spot and future price and their correlation

h* = ps,f x std(s)/std(f)

hedge effectiveness
R^2 = p^2

optimal number of contract
amount of contracts
after having determined the optimal hedge ratio, the amount of futures contract (N) equals the hedging amount (Na) divided by the contract size of the future(Qf), multiplied by the optimal hedge ratio
N = (h*) x (Na/Qf)

stock index future
N* = beta x (P/A) 将beta对冲到零

2. commodity options

long call: right to buy

short call: obligation to sell
short put: obligation to buy
Call options allow the holder to buy the asset at a stated price within a specific timeframe.
Put options allow the holder to sell the asset at a stated price within a specific timeframe.

In options trading, what is the difference between a short call and a long call?
At the core level, a short call is the exact opposite of a long call. A “buying to open” a long call gives a trader the right, but not the obligation, to purchase shares of a stock at a predetermined price on a predetermined date.

On the other hand, “selling to open” a short call obligates a trader to sell shares of a stock at a predetermined price on a predetermined date, assuming the short call is in the money.

For every trader that buys a call option, there was theoretically another who sold that same call option.

在期权交易中，空头和多头有什么区别？
在核心级别，短电话与长电话完全相反。 “买入”多头买权赋予交易者权利，但没有义务在预定日期以预定价格购买股票。

另一方面，“卖空”卖空交易使交易者有义务在预定日期以预定价格出售股票，前提是卖空是在货币中。

从理论上讲，对于每个购买看涨期权的交易者，都有另一个卖出相同看涨期权的交易者。

the difference between ‘in the money’, ‘at the money’, ‘out the money’
期权里面的概念，分别对应in the money实值，at the money 平值， out the money虚值。代表着投资者在期权投资中的盈利、盈亏平衡和亏损三种状态。举例，对于一个股票看涨期权而言，行权价格是20元，对应市场价格有以下情况：如目前市场价格如果是20元，则投资者收益即为20-20=0，此时代表平值期权(at the money)。如果目前市场价格是25元，则投资者收益时25-20=5元，此时代表的是实值期权(in the money)。如果市场价格是15元，则投资者收益即为15-20=-5元，对应的就是虚值期权(out the money)。

A binary option is a financial exotic option in which the payoff is either some fixed monetary amount or nothing at all.[1][2] The two main types of binary options are the cash-or-nothing binary option and the asset-or-nothing binary option. The former pays some fixed amount of cash if the option expires in-the-money while the latter pays the value of the underlying security. They are also called all-or-nothing options, digital options (more common in forex/interest rate markets), and fixed return options (FROs)
二元期权是一种金融异国期权，其收益要么是某个固定的货币金额，要么完全没有。[1] [2] 二元期权的两种主要类型是无现金二元期权和无资产二元期权。如果期权在价内到期，则前者支付一定的现金量，而后者则支付基础证券的价值。它们也被称为“全有或全无”期权，数字期权（在外汇/利率市场中更为常见）和固定收益期权（FRO）

Credit Event Binary Options (CEBOs) are the CBOE’s translation of credit default swaps (CDS) to a regulated and centralized marketplace CEBOs pay a fixed amount if a credit event is confirmed in a reference entity. CEBOs expire worthless if no credit event is confirmed before expiration ‘Credit Event’: Bankruptcy Failure to pay
信用事件二元期权（CEBO）是CBOE将信用违约掉期（CDS）转换为受监管的集中化市场CEBO，如果参考实体中确认了信用事件，则支付固定金额。如果未在“信用事件”到期之前确认任何信用事件，则CEBO会一文不值：破产无法付款

What Is Deep Out Of The Money?
An option is considered deep out of the money if its strike price is significantly above (for a call) or significantly below (for a put) the current price of the underlying asset. Typically, this means the strike price of the option must be more than a few strikes in the option chain away from the price of the underlying asset.

Out of the money options have no intrinsic value and trade on their time value. The deeper out of the money the option, the more exaggerated this becomes. Conversely, in the money options have both intrinsic value and time value.
如果期权的行使价显着高于标的资产的当前价格（看涨期权）或显着低于（看跌期权）当前价格，则该期权被认为是货币深度期权。通常，这意味着期权的行使价必须大于期权链中远离基础资产价格的若干行使。

货币选择权没有内在价值，只能用其时间价值进行交易。期权的钱越深，这种选择就越夸张。相反，货币期权既具有内在价值，又具有时间价值。

profit (期权利润，扣除期权费) 
Long Call: Max(0, ST - X) - c0
Short Call = (profit long)
Long Call: Max(0, X-ST) - p0
Short Put = - (profit of short)

Answer 109

A

option proxy min value max value
European call c max(0, So - Xe^rT) So
American call C max(0, So - Xe^rT) So
European put p max(0, Xe^rT - So) Xe^T
American put P max(0, X - So) X

Answer 110

A

p + S = c + Xe^-rT for European
p + S - D = c + Xe^-rT with dividend
s - X <= C - P <= S - Xe^-rT for American option

Answer 111

A

early exercise:
1. With dividend: Both American call and put option can be delivered early

Without dividend:
American call never exercise early without dividend (American call options = European call options)
American put options may need to exercise early(a. American put option > European put options; b. American put would be exercised when X-S is larger an interest rate is high);

Answer 112

short one call at T1, long one call at T2 (T1 T2)

Calendar spread is a trading strategy for futures and options to minimize risk and cost by buying two contracts or options with the same strike price and different delivery dates.

日历价差是通过在相同的执行价格但交割月份不同的同时对同一基础资产输入多头和空头头寸而建立的期权或期货价差。有时将其称为货到付款，市场内，时间或水平价差。

典型的期权交易包括具有近期到期日的期权（看涨或看跌）的出售，以及具有长期到期日的期权（看涨或看跌）的同时购买。两种期权的类型相同，行使价格相同。

卖出近期看跌/看涨期权
购买长期看跌/看涨期权
最好但不要求隐含波动率低

Answer 116

A

对角点差是通过同时在两个相同类型（两个看涨期权或两个看跌期权）的期权中建立多头和空头头寸而建立的期权策略，但是执行价格不同，到期日不同。通常，这些结构的比率为1 x 1。

根据期权的结构，此策略可能看涨或看跌。

该策略被称为对角线价差，因为它结合了水平价差（也称为时间价差或日历价差）（代表到期日期的差异）与垂直价差或价格价差（其代表行使价的差异）。

水平，垂直和对角线价差是指每个选项在选项网格上的位置。期权以行使价和到期日的矩阵形式列出。因此，垂直传播策略中使用的期权都在同一垂直列中列出，并具有相同的到期日期。横向点差策略中的期权使用相同的执行价格，但到期日期不同。因此，这些选项在日历上水平排列。

对角价差中使用的期权具有不同的行使价和到期日，因此期权在报价网格上以对角线排列。

strip (long one call, long two put)
赌波动，投资者认为股价下跌可能性更大

strap （long two call, long one put）
赌波动，投资者认为股价上涨可能性更大

Answer 119

A

利率上限是一种利率衍生工具，在这种利率衍生工具中，买方在利率超过商定的行使价的每个期间结束时收到付款。上限的示例是协议，规定每个LIBOR利率超过2.5％的月份都将收到付款。

同样，利率下限是衍生合同，在该合同中，买方在利率低于商定的行使价的每个时期结束时收到付款。

上限和下限可以用来对冲利率波动。例如，以贷款LIBOR利率支付的借款人可以通过购买2.5％的上限来保护自己免受利率上升的影响。如果在给定期间的利率超过2.5％，则可以使用从衍生工具收取的款项来帮助支付该时期的利息，因此从借款人的角度来看，利息支付实际上被“限制”在2.5％以内。

long cap is looking like long call, the strike price is Cap strike

long floor is looking like long put, the strike price is floor strike

Answer 120

A

packages:
zero cost initially
example: bull, bear, butterfly

transformation of American options:
Bermuda options: early exercise may restricted to certain dates
initial lookout period: early exercise may be somehow restricted
warrants: strike price may change during the life of an option

volatility and variance swap
volatility swap
在金融中，波动掉期合约是针对给定基础资产在未来实现的波动率的远期合约。波动掉期允许投资者直接交易资产的波动，就像交易价格指数一样。到期时的收益等于
[std(realised) - Kvol] x Nvol
std(realised): is the annualised realised volatility
Kvol: is the volatility strike
Nvol: is a preagreed notional amount.

variance sway
The features of a variance swap include:
the variance strike
the realized variance
the vega notional: Like other swaps, the payoff is determined based on a notional amount that is never exchanged. However, in the case of a variance swap, the notional amount is specified in terms of vega, to convert the payoff into dollar terms.
The payoff of a variance swap is given as follows:
[variance notional (a.k.a. variance units) - annualised realised variance] x variance strike

hedging exotic option
dynamic option replication
1. 大牛市中保本策略是大幅跑输市场的，但是风险资产的投资比重也是不断上升的，分享了一部分市场走强带来的收益，但其回撤真是小得让人嫉妒。

大熊市中OBPI保本策略是能够打败市场的，但是其也小幅亏损了，由于保本比率设置为95%，所以其亏损幅度也是满足要求的。并且在股灾2.0期间，风险资产的占比接近于0，基本完全持有国债了，所以其表现还是可圈可点的。
震荡市中，保本策略小幅盈利，虽然跑输了大盘，但是走的比较平稳，风险资产与无风险资产的仓位一直都保持得比较稳定。

static option replication
与Delta对冲相比，该对冲的好处在于不需要经常调整头寸。静态期权复制的应用范围非常广泛，尤其在障碍期权的对冲中十分常见。

gap options
There are two strike price. X1 is the exercise price and X2 is the trigger price

X1 could different from X2
if X1 =X2, gap option equals on ordinary European option.

for a gap call, if X2 >X1:
if S > X2, payoff = S - X1
if S <= X2 payoff = 0

for a gap put, if X2 < X1:
if S < X2, payoff = X1 - S
if S >= X2 payoff = 0

forward start option
start at a specified future date with an expiration date set further in the future
从指定的将来日期开始，并在以后设置的到期日期

compound options (复合期权)
call on call
investor has the right to buy the underlying call option on the expiration date
call on put
investor has the right to buy the underlying put option on the expiration date
put on call
investor has the right to sell the underlying call option on the expiration date
put on put
investor has the right to sell the underlying put option on the expiration date

chooser option
long position has the right to choose whether the option is a call or put
the value of the chooser option at this point is MAX(c,p)

Barrier option:

knock-out options
触发障碍，期权失效
down-and-out call / up-and-out call
down-and-out put / up-and-out put

know-in options 
触发障碍，期权生效
down-and-out call / up-and-out call
down-and-out put / up-and-out put

binary options
cash-or-nothing 
payoff of either a fixed amount money or nothing 
asset-or-nothing 
payoff  of either an asset or nothing

lookback option
Also known as a hindsight option, a lookback option allows the holder the advantage of knowing history when determining when to exercise their option. This type of option reduces uncertainties associated with the timing of market entry and reduces the chances the option will expire worthlessly. Lookback options are expensive to execute, so these advantages come at a cost.

可让买家最大程度地减少后悔。
回溯选项仅在柜台（OTC）上可用，而在任何主要交易所中均不可用。
这些选择的建立成本很高，而潜在的利润通常被成本抵消。

回溯期权：回溯期权的bai收益依附于标的资产在某个du确定的时段(称为zhi回溯时段)中达到的最dao大或最小价格(又称为回溯价)，根据是资产价还是执行价采用这个回溯价格。

a good solution to memory for call option:
for European call option: V = MAX(0, S - X)
for fixed lookback call option:V = MAX(0, Smax - K)
for floating lookback call option:V = MAX(0, S - Smin)

memory for put option:
for European call option: V = MAX(0, S - X)
for fixed lookback call option: V = MAX(0, K - Smin)
for floating lookback call option: V = MAX(0, Smax - S)

Shout options
A shout option is an exotic option contract that allows the holder to lock in intrinsic value at defined intervals while maintaining the right to continue participating in gains without a loss of locked-in monies. The option buyer “shouts” at the option writer to lock in the gain, yet the contract still remains open. The shout guarantees a minimum of profit, even if the intrinsic value decreases after the shout. If the option increases in value after the shout, the option buyer can still participate in that.

A shout option allows the buyer to lock in the intrinsic value of an option by “shouting” at the writer to do so.
Shout options are exotic options, and therefore their terms can be negotiated.
Shout options are more expensive than standard options because of their flexibility to lock in profit while still participating in future profit.

Holders can “shout” to the writer at one time during it life
receive either the usual payoff from a European option or the intrinsic value at the time of the shout, whichever is greater

Asian option
c = MAX(Save(t, T) - X, 0)
cheaper than regular options

Exchange options
Exchange one asset for another

rainbow options
1. two or more sources of uncertainty
2. call or put on the best or worst of n underlying, or options which pay the best or worst of n assets
3. Right for the short position to pick up the most appropriate bond to deliver
E.g. T-bond futures contract
