This financial tool calculates an investment’s performance by considering the size and timing of cash flows. For example, it accounts for deposits, withdrawals, dividends, and their respective dates, providing a more accurate return representation than simpler methods when cash flows are irregular. It differs from the time-weighted return, which isolates investment performance from the impact of cash flows.
Accurately assessing investment performance is crucial for informed decision-making. This particular method offers a holistic view by incorporating the impact of an investor’s actions, such as additional contributions or withdrawals. This approach became increasingly relevant with the rise of online brokerages and easier access to investment accounts, allowing for more frequent transactions compared to the past where buy-and-hold strategies were more common.
