CFA Level3 Flashcards
1
Q
Geometric Smoothing
A
Determines foundation distributions partly by Beginning MV X distribution % and partly as previous distribution increased for inflation, this creates a less volatile distribution %
2
Q
Output gap
A
Below trend line growth and associated with a declining rate of inflation
3
Q
Taylor Rule
A
Forecast the next change in ST rates
R target = policy neutral ST rate + 0.5 (expected inflation - target inflation) + 0.5 (expected GDP - trend GDP growth)
4
Q
Cobb Douglas (CD) Production Function
A
Change Y/Y = Change A/A + a(Change k/k) + (1-a)Change L /L
Y = real output
A = total factor productivity
a = output elasticity
5
Q
Solow Residual
A
Estimating TFP
Change in A = Change in Y - a(K) - (1-a)(L)
6
Q

15
Q
Components of Fixed Income return
A

- Rolldown return (projected ending / beg price) - 1
- Manager predicted price change based on D,C, and spread change
- Projected credit losses
- Projected foreign currency G/L
16
Q
Duration Gap
A
BPVa - BPVl
17
Q
Rules for Immunizing a single liability
A
- Initial PVA >= PVL
- Portfolio Macaulay duration Da = Dl
- Minimize portfolio convexity (min dispersion of asset cash flows around the liability and reduce risk to curve reshaping)
18
Q

- Pure Indexing
- Enhanced Indexing
- Active Management
21
Q
Collar
A
Long and short position in an out of the money call and put
22
Q
Enhanced Indexing
A
Matching index duration but allowing deviations in other exposures
23
Q
Key Rate Duration
A
Controls both interest rate and yield curve risk
24
Q
Matrix / Evaluated Pricing
A
Price of similar, traded bonds is captured and used to calculate YTM
25
Modified Duration
Minimize tracking error due to parallel shifts in the yield curve
Change in value = -MD Change in rates
26
Key rate duration
Minimize tracking error due to nonparallel changes in the yield curve
Multiple key rates for single points in the yield curve = -D* change in rates
27
Advantages of a Laddered Bond Portfolio
1. Natural liquidity
2. Broadest diversification of cash flow across time and yield curve
3. Diversification between price and reinvestment risk
4. More convexity than the bullet, benefit from large parallel shifts
5. Falls in middle of non parallel shifts
28
Strategies for an unchanged (Upward Sloping) Yield Curve (5)
1. Buy and Hold
2. Riding the yield curve
3. Selling Convexity
4. Carry Trades
29
Buy and Hold
Higher return by shifting to higher duration, buying duration risk to enhance portfolio yield under the assumption rates will remain stable
30
Selling Convexity
In a stable rate environment, increase portfolio returns by reducing the portfolio convexity below the benchmark
- Sell calls and sell puts
- Buy callable bonds and MBS (negative convexity)
31
Carry Trade
Buying a security at a higher yield and financing the purchase by borrowing at a lower interest rate
- Do best in stable markets can be very risky in highly volatile markets
32
Interest Rate Parity
Higher yield currency will trade at a forward discount to the lower yield currency
33
Crowding Risk
Mass effort to unwind a trade
34
Strategies for Changes in Level, Slope, or Shape of the Yield Curve
1. Adjusting duration
2. Increasing convexity
3. Bullet, laddered and barbell strategies
35
Rolldown price

36
Holding Period Return
(Projected Price + coupon) / beginning price
37
G Spread

39
OAS
Option Adjusted Spread
| does not reflect the impact of options on expected return
40

41
Roy's Safety-first criterion
Rp - RL / standard deviation of portfolio
42
Myopic Loss Aversion
Macro issue when a large number of investors under-allocate to stocks, keeping their prices low and biasing upward their return
43
Conservatism
Cognitive Error
| Initially rational view is formed but then retained without further consideration as new information comes in
44
Sharpe Ratio
Annualized Return - annualized risk free rate / Annualized standard deviation
45
Contagion
During crisis periods of market decline, correlations between markets move upwards towards +1 and benefits of diversification are not present
Tool used to track = Conditional Correlation matrices (Correlation for normal and for crisis)
46
Unhedged Return in Foreign Asset
R (FC) + R (FX)
47
Hedged Return in a Foreign Asset
R (FC) - R (FX) + R (DC)
48
Decision Risk
Investors investing in securities they do not really understand and then exiting the strategy at an inopportune time and at a high cost, higher for PE because it is an illiquid asset
- Ability to exit lowers decision risk
49
Information Ratio
Active risk / Active return
IR = IC X IB (1/2)
IC = Information Coefficient
IB = investor Breadth
50
Joint Probability
Prob 1 + Prob 2 - (Prob 1 X Prob 2)
51
Advantages of Monte Carlo Simulation
1. Focuses the client and manager on most important risk, outliving the assets. instead of short term volatility
2. Visually displays for the client the prospects of outliving assets
3. Can incorporate path dependency issues such as how changes in inflation affect both distributions and MC
4. Can incorporate taxes and other factors in addition to return
52
Event Risk
Company or situation specific and would be important if it causes bonds to decline relative to the stock of the company
53
Market Liquidity Risk
Significant for distressed debt investors, illiquid securities that most investors avoid
54
Market Risk (Distressed Investing)
Long company's bonds and short the stick is designed to remove market (systematic) risk
55
J Factor Risk
The effect of the judge on the results of any bankruptcy proceedings, may rule in favor of debt or equity which will impact returns
56
Treynor Measure
Excess return over the risk free rate per unit of systematic risk
R portfolio - rfr / Beta
57
M^2
Compares the risk adjusted portfolio return to the market return
Rf + (Rp - Rf)/std dev p) *stand dev market
58
Information Ratio
Excess return for standard deviation of excess risk
Active Return / Active risk
(Rp - Rb) / standard dev (Rp - Rb)
59
Jensen's Alpha

61
Components of Implementation Shortfall (4)
1. Commissions
2. Delay in execution [BP - DP] X # shares later executed
3. Realized Profit / Loss [ EP - DP] X # of shares at EP
4. Missed Trade [CP - DP] X shares canceled
62
Fundamental Law of Active Management
IR = IC * Sq root of IB
Information ratio = Information coefficient (Depth of knowledge about individual securities) X number of investment decisions (IB)
63
Investor Breadth (IB)
Number of independent decisions an investor makes
| Ex: Buy ten energy stocks, IB = 1
64
Information Coefficient (IC)
Investor's forecast against actual outcomes
| Skillful managers will have higher ICs
65
Decentralized Risk Governance
Places responsibility for execution within each unit of the organization
- Benefit: putting risk management in the hands of those closest to each part of the organization
66
Centralized Risk System (ERM)
Enterprise Risk Management System
| Places execution within one central unit of the organization
67

1. Operational Risk
2. Settlement Risk (Herstatt Risk)
3. Model Risk
4. Sovereign Risk
5. Regulatory Risk
6. Tax, Accounting and Legal Contract Risk
69
Analytical VAR
- based on concept of one-tailed confidence intervals
VAR = (Rp - (z)(standard dev))*Value of portfolio
5% = 1.65 standard deviation below mean
1% = 2.33 standard deviation below mean
70
ROMAD
Rp / Max drawdown
71
Sortino Ratio

Covariance (i,m) / Variance (m)
73
Adjusting Portfolio Beta
(Bt - Bp)/Bf *(Vp/Pf(multiplier))
74
Basis Risk
Item hedged in numerator, not perfect match for hedging vehicle in denominator
75
Effective Beta
% change in value of the portfolio / % change in index
76
Pre-investing
Buying contracts in anticipation of cash that will be received
77
Bull Spread
Provides limited upside if underlying rises (bull) with limited downside
- Purchase a call with low exercise price Xl and subsidize with selling a call with a higher exercise price X
78
Bear Spread
Limited upside if underlying declines (bear) with limited downside
Sell a call with a low strike price and buy a call with a high strike price
79
Butterfly Spread with Calls
Purchase or sale of 4 different call options of three different types
- Buy 1 call with low exercise price XL
- Buy 1 call with higher exercise price XH
- Write 2 calls with an exercise price in-between Xm
80
Straddle
Purchase a call option and a put option with same exercise price and expiration
81
Collar
Protective Put and Covered Call
- Goal is for the owner of the underlying security to buy a protective put and then sell a call t pay for the put premium
- Upside and downside are limited
- Good strategy for locking in value of a portfolio at a minimal cost
82
Interest Rate Call Option Payout
Payoff = NP (Max(0, LIBOR - strike price)(D/360)
83
Delta
Change in price of the option / Change in price of the underlying
Range from 0 (OTM) to 1 (ATM)
84
Delta Hedge Position
= - delta X number of options
85
G spread
Similar to benchmark spread, but uses interpolated YTM of the two closest bracketing on the run government bonds
86
I spread
Compare interpolated YTM of the two closes bracketed swap fixed rates
87
OAS
Best estimate of spread for bonds with options
88
Grinold - Kroner Model
| Forecasting return
R = Div1/P0 + i + g - Change shares - change P/E
89
Active Weight
= current allocation - benchmark
90
Alpha / Beta Separation Strategy
Gain systematic risk exposure by allocating funds to (low cost) passive index strategies, while adding to alpha via market-neutral long/short managers
