Exam-relevant equations keyed by topic, with variable definitions, units, and typical ranges.
Quantitative Analysis
$$ Sharpe Ratio = \frac{E[R_p] - R_f}{\sigma_p} $$
VARIABLES
- E[R_p]: Expected return of the portfolio
- R_f: Risk-free rate
- \\sigma_p: Standard deviation of portfolio returns
Typical Range: 0.5 to 2.0+ for top-quartile funds
$$ Sortino Ratio = \frac{E[R_p] - MAR}{TDD} $$
VARIABLES
- MAR: Minimum Acceptable Return (often the risk-free rate)
- TDD: Target Downside Deviation
Typical Range: Often higher than Sharpe for trend-following strategies
Real Estate
$$ Value = \frac{NOI}{Cap\ Rate} $$
VARIABLES
- NOI: Net Operating Income (Gross Potential Income - Vacancy - Operating Expenses)
- Cap Rate: Capitalization Rate
Typical Range: 4% to 8% depending on property type and environment
$$ DSCR = \frac{NOI}{Annual\ Debt\ Service} $$
VARIABLES
- NOI: Net Operating Income
- Annual Debt Service: Principal + Interest payments for the year
Typical Range: Lenders typically require > 1.20x
Private Equity
$$ MOIC = \frac{Realized\ Value + Unrealized\ Value}{Total\ Invested\ Capital} $$
VARIABLES
- Realized Value: Cash already distributed to LPs
- Unrealized Value: The estimated NAV of remaining assets
- Invested Capital: Capital drawn down from LPs
Hedge Funds
$$ Total\ Fee = Management\ Fee + Incentive\ Fee $$
VARIABLES
- Management Fee: Typically 1-2% of AUM
- Incentive Fee: Typically 15-20% of Profits (subject to HWM and Hurdle Rate)
