• Is the return after all expenses adequate compensation for the risk?
• What changes should be made if the compensation is too small?
• Performance must be evaluated before answering these questions
• Without knowledge of risks taken, little can be said about performance

Equates initial value of portfolio (investment) with cash inflows or outflows and ending value of portfolio
Cash flow effects make comparisons to benchmarks inappropriate
• Time-weighted returns
Captures cash flows during the evaluation period and permits comparisons with benchmarks
Calculate a return relative for each time period defined by a cash inflow or outflow
Use each return relative to calculate a compound rate of return for the entire period
• Dollar- and Time-weighted Returns can give different results
Dollar-weighted returns appropriate for portfolio owners
Time-weighted returns appropriate for portfolio managers
• No control over inflows, outflows
• Independent of actions of client
• Risk differences cause portfolios to respond differently to market changes
• Total risk measured by the standard deviation of portfolio returns
• Systematic risk measured by a security’s beta
