Sharpe ratio: (Portfolio return - risk-free rate) / standard deviation
Example: Return 9%, T-bills 3%, SD 12%: (9 - 3) / 12 = 0.50.
Current ratio / quick ratio: Current assets / current liabilities; (current assets - inventory) / current liabilities
Example: CA $500K, inventory $200K, CL $250K: current = 2.0; quick = 1.2.
Future value: PV x (1 + r)^n
Example: $10,000 at 6% for 10 years: 10,000 x 1.06^10 = $17,908.
Time-weighted vs. dollar-weighted: TWR removes the effect of client cash flows; DWR (IRR) includes them
Example: Judging a manager: use TWR. Judging the client's own experience: DWR.
