Frequently Asked Questions
How do you calculate portfolio return?
Simple portfolio return = (Ending Value - Beginning Value - Net Contributions) / Average Investment. Weighted portfolio return = Sum of (Weight x Return) for each asset in the portfolio.
What is time-weighted return?
Time-weighted return (TWR) eliminates the impact of cash flows (deposits/withdrawals) to measure pure investment performance. It chains together sub-period returns and is the industry standard for comparing fund managers.
How do cash flows affect portfolio return?
Cash flows (contributions and withdrawals) impact dollar-weighted returns. The Modified Dietz method approximates the timing of cash flows by assuming they occur at the midpoint of the period.
