CHAPTER 2: AI PERFORMANCE & RETURNS Flashcards
WHY IS IT DIFFICULT TO CONDUCT PERFORMANCE APPRAISAL ON AI
- ASYMMETRIC RISK-RETURN PROFILES
- LIMITED PORTFOLIO TRANSPARENCY
- ILLIQUIDITY
- PRODUCT COMPLEXITY
- COMPLEX FEE STRUCTURES
SHARPE RATIO
(Rpf-Rf)/Sigma or SD of portfolio
SD measures volatility
PROS: Easy to calculate
CONS:
- Penalizes both upside & downside volatility equally (only left side curve volatility is dangerous in the sigma normal distribution curve i.e. symmetrical distribution on both LHS & RHS)
- Assumes normal distribution.
However, AIs often display non-normal return distributions with signficiant skewness & kurtosis. This makes sharpe ratio a less-than-ideal performance measure for AIs
RISK-ADJUSTED RETURN RATIOS
STSC: sigma, beta, downside sigma, max drawdown
SHARPE: (Rpf-Rf)/sigma pf
TREYNOR: (Rpf-Rf)/B
SORTINO: (Rpf-Rf)/downside sigma
SD doesn’t differentiate upside or downside risk; in long-term investing- upside risk isn’t really a risk
CALMAR: (Rpf-Rf)/max drawdown
Jensen’s Alpha: Rpf-Ke
SORTINO RATIO
(Rpf-Rf)/Downside Deviation or Sigma of PF
PROS: Doesn’t penalize upside volatility & instead focus is on downside
CONS: Difficult to calculate
MAR RATIO
Avg CAGR/Max. Drawdown (Since Inception)
Measures average return relative to the worst drawdown loss (distance between a peak & trough of a portfolio). It uses full-investment history of portfolio since inception
MAR RATIO= Fund Avg. CAGR (since inception)/Max Drawdown (since inception)
Higher the MAR ratio, better an AI asset performed on a risk-adjusted basis over a specific period of time
PRO: Shows entire history
CON: doesn’t specifically focus on recent performance which may be more relevant for the investor
CALMAR RATIO
Avg CAGR/Max Drawdown (Last 3 years)
Variation of MAR ratio
Fund Avg. CAGR (last 3 years)/Max drawdown (last 3 years)
PRO: Focuses on recent performance
CON: Hides past issues
PE & RE PERFORMANCE EVALUATION
BOTH have a J-CURVE EFFECT
Initial -ve decline followed by strong growth over long-term
Both require significant initial cash outlays & investments take some time to turn profitable
Thus, short-term performance measures must NOT be used. Instead use:
- IRR for PE
- MOIC for PE
- Cap Rate for RE
IRR
ASSUME NPV= 0 (Breakeven Point)
IRR= discount rate that makes NPV= 0
0 = -Inv + CF/(1+r)^n + CF/(1+r)^n+1…
IRR= make CFs equal to inital investment
Inv= CF/(1+R)^N + CF/(1+R)^N+2
If R>r, then accept; else reject
i.e. IRR>WACC= accept; else reject
R= opportunity cost of capital or minimum rate of return
ASSUMPTIONS:
- must know about cost of financing outgoing CFs (typically WACC) & Reinvestment Rate assumptions (i.e. reinvested @IRR rate) for outgoing CFs to make incoming CFs (must be assumed & may not be earned)
PERFORMANCE OF PRIVATE EQUITY
MULTIPLE OF INVESTED CAPITAL (MOIC)
eg: (Realized+Unrealized)/Total Inv Capital
eg: 1.2
means
1= starting point
20%= what you’ve earned on top
To overcome complexity/drawbacks of IRR, MOIC or money multiple is used
Simply measures the total value of all distributions
and
residual asset values relative to an initial total investment
MOIC= (Realized Value of Inv + Unrealized Value of Inv) / Total amount of Invested Capital
Although simple to calculate, a major drawback of MOIC is that it ignores the TIMING of CFs
PERFORMANCE OF REAL ESTATE
Cap Rate= Rent/Investment
Cap rate= Rent/Investment
Cap rate is r-g in Gordon’s growth model
Value of Property= Rent/Cap Rate
Calculated as annual rent actually being earned divided by the price originally paid for the property
eg: 10M/100M= 10%
10% is cap rate
CAP RATE= CAPITALIZATION RATE
Used to value properties
eg:
Giving $10M Rent/0.1 i.e. cap rate of similar properties to come up w property’s value (based on relative valuation)
HEDGE FUNDS: LEVERAGE, ILLIQUIDITY & REDEMPTION TERMS
LEVERAGE: used to enhance returns
To lever their portfolio, HFs use derivatives or borrow capital from prime brokers
HFs must deposit cash or other collateral into a margin account w the prime broker, who then lends securities to the HF
If the margin account falls below a certain threshold, a margin call is issued, and the HF is required to put up additional collateral
This can magnify a HF’s losses because it may have to liquidate the losing position to meet the margin call
eg: deposited 100M w broker as margin
LONG 1000M
SHORT 1000M
Beta= 0
Both positions offset each other
Now,
LONG 1000M: 10% gain
SHORT 1000M: 8% loss
2% net profits
2% * 1000M= 20M profits
20M made over 100M deposits = 20/100= 20%
Leverage used to multiply returns
HF: ILLIQUIDITY & REDEMPTION TERMS
HFs are valued on a daily, weekly, monthly &/or quarterly basis
Value of HF depends on Value of underlying positions
Price used for valuation depends on whether market prices are available & if the underlying position is liquid
When market prices are available, the fund decides what price to use
Common practice is to quote at the average of the bid & ask prices
A conservative approach is to use bid prices for long & ask prices for short
GAAP ACCOUNTING RULES CATEGORIZE HFs into 3 buckets
L1= use publicly traded prices
L2= use broker quotes
3= use internal models
LEVEL 1: Exchange-traded; publicly traded price is available & is used for valuation purposes
LEVEL 2: when such price isn’t available, outside broker quotes are used.
LEVEL 3: when broker quotes aren’t available or are unreliable, as a final recourse, assets are valued using internal models
LEVEL 3
L3 asset values require additional scrutiny from investors
Models used must be APPROPRIATE + CONSISTENT
Values obtained may not reflect true liquidation values.
Also, the returns may be smoothed & volatility understated
Another factor that can magnify losses for HFs is REDEMPTION PRESSURE
Redemptions usually occur when HF is performing poorly
Redemptions can force HF managers to liquidate positions at disadvantageous prices
TO DISCOURAGE REDEMPTIONS, HFs:
LOCKUP PERIOD
NOTICE PERIOD
REDEMPTION FEES
- Charge redemption fees (typically payable to the remaining investors) to offset the transaction costs for remaining investors
- Use notice periods (investors need to inform the fund manager in advance before making redemption) which provides the HF manager an opportunity to liquidate positions in an orderly manner
- HFs use lockup period (time periods when investors can’t withdraw their capital) which provides the HF manager sufficient time to implement his inv strategy
