25
Volatility skew
The skewed plot (of implied volatility (y axis) against strike price (x axis) for options on the same underlying with the same expiration) that occurs when the implied volatility increases for OTM puts and decreases for OTM calls, as the strike price moves away from the current price
26
Risk reversal
a strategy used to profit from the existence of an implied volatility skew and from changes in its shape over time. A combination of long (short) calls and short (long) puts on the same underlying with the same expiration is a long (short) risk reversal
27
Term structure of volatility
The plot of implied volatility (y axis) against option maturity (x axis) for options with the same strike price on the same underlying. Typically, implied volatility is not constant across different maturities - rather, it is often in contango, long-term options implied volatilities are higher than near-term ones
28
Implied Volatility surface
a 3-dimensional plot, for put and call options on the same underlying asset, of days to expiration (x axis), option strike prices (y axis), and implied volatilities (z axis). It simultaneously shows the volatility skew (or smile) and the term structure of implied volatility
29
Interest rate Swap
OTC contract between two parties that agree to exchange cash flows on specified payment dates - one based on a variable interest rate and the other based on a fixed rate - determined at the time the swap is initiated
30
Swap tenor
when the swap is agreed to expire
31
Basis risk
Spread risk, or the difference between the market performance of the asset and the derivative instrument used to hedge it basis = bond - futures
32
Forward rate agreement
OTC derivative instrument that is used mainly to hedge a loan expected to be taken out in the near future or to hedge against changes in the level of interest rates in the future
33
The preferred instrument to hedge bond positions
Fixed income futures, given that their liquidity is high
34
Principal invoice amount
(futures settlement price/100) * CF * Contract Size
35
If the basis is negative how would a trader make profit
Buying the basis - purchasing the bond and shorting the futures basis = bond - futures
36
If the basis is positive, how would a trade make profit
Selling the basis - sell the bond and buy the futures basis = bond - futures contract
37
Hedge Ratio (HR)
Number of fixed-income futures contracts to be sold or purchased Change in value of the bond portfolio (Delta P) = HR * change in value of the fixed income futures (Delta F) HR = (Delta P / Delta CTD) * CF
38
Portfolio's target basis point value
BPV = MDUR * 0.01% * MV
39
Basis point value hedge ratio (BPVHR)
- BPV (P) / BPV (CTD) * CF
40
Cross-currency basis swap
A swap in which notional principals are exchanged because the goal of the transaction is to issue a more favorable funding rate and swap the amount back to the currency of choice
41
Equity Swap
Derivative contract in which two parties agree to exchange a series of cash flows whereby one party pays a variable series that will be determined by a single stock, a basket of stocks, or an equity index and the other party pays either a variable series determined by a different equity or rate or a fixed series
42
Disadvantages to equity swaps
1) Require putting up collaterals 2) Relatively illiquid contracts 3) Do not confer voting rights
43
Advantages of equity swaps
1) When access to a specific market is limited 2) Taxes are levied for owning physical stocks (stamp duty) but not on swaps 3) Custodian fees are high 4) Cost of monitoring the stock position is elevated (corporate actions)
44
Number of equity futures contracts to buy or sell
NF = ((BT - BS) / BF) * (S/F)
45
Cash securitization (equitization/cash overlay)
Strategy designed to boost returns by finding ways to "equitize" unintended cash holdings N(f) = (B(t) / (B(f)) * (S/F) N(f) = number of futures contracts B(t) = target beta B(f) = beta of futures S = portfolio market value F = one futures contract value
46
VIX
"fear index", measure of investor's expectations of volatility in the S&P500 over the next 30 days
47
Payoff at settlement of a variance swap
(variance notional) * (realized variance - variance strike) variance notional = vega notional / 2 * strike price
48
Vega Notional
The trade size for a variance swap, which represents the average profit and loss of the variance swap for a 1% change in volatility from the strike
49
What two things do variance swap traders typically agree on
1) A variance swap trade size expressed in vega notional (not in variance notional) 2) The strike (x), which represents the expected future variance of the underlying, expressed as volatility (not variance)
50
Variance notional
The notional amount of a variance swap; it equals vega notional divided by two times the volatility strike price (vega notional) / (2 * strike price)
51
Rule of thumb for strike of a variance swap
Typically corresponds to the implied volatility of the put that has 90% moneyness (calculated as the option's strike divided by the current level of the underlying)
52
Effective federal funds rate (FFE)
The fed funds rate actually transacted between depository institutions, not the Fed's target federal funds rate
53
Probability of a change in the federal funds rate
(Effective federal funds rate implied by futures contracts - current federal funds rate) / (federal funds rate assuming a rate hike - current federal funds rate)
54
How much of the foreign exchange market do spot markets account for
less than 40%
55
FX Quoting Hierarchy
1) Currency pairs using EUR, EUR base 2) Currency pairs using GBP, other than EUR, GBP base 3) Currency pairs using AUD or NZD, other than EUR and GBP, AUD/NZD base 4) All other currency quotes using USD, USD base
56
Two forms of hedging costs
Trading costs and opportunity costs
57
Currency overlay program
Program to manage a portfolio's currency exposures for the case in which those exposures are managed separately from the management of the portfolio itself
58
All else equal, the base currency's real exchange rate should appreciate if there is an upward movement in...
1) Long-run equilibrium real exchange rate 2) Real or nominal interest rates, which should attract foreign capital 3) Expected foreign inflation, which should cause the foreign currency to depreciate 4) Foreign risk premium, which should make foreign assets less attractive compared with the base currency nation's domestic assets
59
Carry trade
A trading strategy that involves buying a security and financing it at a rate that is lower than the yield on that security
60
Forward rate bias
The persistent violation of uncovered interest rate parity uncovered interest rate parity states that forward rates are unbiased predictors of future spot rates, but this is empirically false, so therefore, it is a biased predictor
61
Return distribution of the carry trade
Pronounced negative skew
62
Is higher/lower volatility better for the carry trade
lower
63
Most important Greek traded
Vega
64
Why do institutional investors prefer forwards over futures when hedging currency trades
1) Futures contracts are standardized, which may not be exactly what they need 2) Futures contracts may not always be available in the currency pair that the PM wants to hedge 3) futures contracts require up-front margin (initial margin), as well as have intra-period cash flow implications
65
Static Hedge
A hedge that is not sensitive to changes in the price of the asset hedged
66
Dynamic hedge
A hedge requiring adjustment as the price of the hedged asset changes
67
Put spread
A type of short risk reversal position used to reduce the upfront cost of buying a protective put Involves buying an OTM put option and writing another deeper OTM put option
68
Seagull spread
An extension of the risk reversal foreign exchange option strategy that limits downside risk Long a protective put and then write both a call and deep OTM put
69
Knock-in/Knock-out
Features of a vanilla option that is created (or creases to exist) when the spot exchange rate touches a pre-specified level (barrier)
70
Cross hedge
A hedge involving a hedging instrument that is imperfectly correlated with the asset being hedged; for example, hedging a bond with futures on a non-identical bond
71
Proxy hedge vs. Cross hedge
Proxy hedge removes the foreign currency risk by hedging it back to the investor's domestic currency, while a cross hedge moves the currency risk from one foreign currency to another foreign currency
72
Minimum-variance hedge ratio
A mathematical approach to determining the optimal cross hedging ratio (running a regression) correlation * (risk of one/risk of other)
73
2 Considerations when managing emerging market currency exposures
1) Trading costs are higher (thinly traded) 2) Increased likelihood of shit hitting the fan
74
Non-deliverable forwards
Forward contracts that are cash settled (in the non-controlled currency of the currency pair) rather than physically settled (the controlled currency is neither delivered nor received)
75
synthetic long put
long call + short shares
76
theta for short stock + put position
positive
77
theta for short stock + long call
negative
78

79
amount of cash exchanged at initiation of a variance swap
0
80
what does it mean to sell the basis
sell the bond and buy the futures
81
deriving the probability of a rate move by the FOMC
1) Calculate FFE from contract price: | 100-contract price | 2) (FFE - current contract price) 3) Federal funds rate assuming a rate cut (if contract price is below 100) - current FFE 4) step 2 / step 3
82
Currency swap - cash flows at inception
two parties pay the notional of the contract they agreed to enter into
83
Currency swap - periodic cash flows
payments based on floating rate
84
Currency swap - cash flows at maturity
notional principal in respective currencies
85
return of domestic currency
R(DC) = (1+R(FC))*(1+R(FX))-1
86
difference between currency swaps and fx swaps
fx swaps don't have intermediate cash flows and are typically shorter r
87
time horizon needed for active currency management
long-term
88
4 situations that will cause real exchange rate of base currency to appreciate
upward movement in: 1) long-run equilibrium real exchange rate 2) real/nominal interest rates -- this attracts foreign capital 3) expected foreign inflation -- foreign currency will depreciate 4) foreign risk premium -- makes foreign assets less attractive compared to base currency nation's domestic assets
89
most significant factor to consider when using futures contracts
margin requirements
90
delta exposure in straddle
delta neutral
91
what side of the volatility trade do volatility traders set up as
net-short volatility most options expire out of the money, and the option writer then gets to keep the option premium without delivery of the underlying
92
hedgers position themselves how in regards to volatility
long-volatility they are buying protection from unanticipated price volatility
93

0 to -0.5 0 being more OTM
94
ATM delta for put option
-0.5
95
OTM delta range for call options

97
total return swap vs equity swap
total return swap includes dividends
98
disadvantages of equity swaps
1) require putting up collateral 2) illiquid 3) do not confer voting rights (possibly a reason why you would do it)
