Rolling Returns vs Trailing Returns in Mutual Funds

In summary

Rolling returns and trailing returns help you assess a mutual fund’s historical performance in different ways. Using both can provide a more balanced view when comparing schemes.

• Rolling returns: Measure annualised performance across multiple overlapping periods to help assess consistency.
• Trailing returns: Measure performance between a fixed start date and an end date, such as one, three, or five years.
• Key difference: Rolling returns show how performance varies across periods, while trailing returns provide a snapshot for a selected timeframe.
• Best use: Compare rolling returns to assess consistency and trailing returns to understand performance over a specific period.
• Limitations: Both rely on historical data and cannot predict future returns.
• Better comparisons: Use the same timeframe, benchmark, and return basis when comparing funds.

Neither metric should determine an investment decision on its own. Consider costs, portfolio composition, risk, and your financial goals before selecting a scheme.

Rolling returns measure a mutual fund’s annualised performance over a fixed duration, calculated repeatedly using different start and end dates. For example, a three-year rolling return analysis calculates returns for successive three-year periods across the available historical data.

You can use rolling returns to understand how a scheme performed across different market conditions rather than relying on a single period. This helps you assess the consistency of its historical performance.

However, rolling returns do not predict future performance. Results also depend on the selected duration, calculation frequency, and available historical data.

Trailing returns measure a fund’s performance between two specific dates. Mutual fund factsheets commonly show trailing returns for periods such as one year, three years, and five years.

These figures help you review a fund’s performance over a selected period. You can also use mutual fund returns to understand how different return measures are presented.

Trailing returns are straightforward to compare, but the result can change significantly depending on the chosen end date. A strong recent figure may not reflect the fund’s performance across earlier market conditions.

Here are the differences between rolling returns and trailing returns:

For a fuller performance evaluation of a mutual fund, compare both metrics with the fund’s benchmark and assess the risks taken to generate returns.

Here is how rolling and trailing returns are calculated:

Calculating trailing returns

For a simple holding period, use the absolute return formula:

[
\text{Absolute return}=\frac{\text{End value}-\text{Start value}}{\text{Start value}}\times100
]

For annualised performance over multiple years, the compound annual growth rate (CAGR) formula is:

[
\text{CAGR}=\left[\left(\frac{\text{End value}}{\text{Start value}}\right)^{1/n}-1\right]\times100
]

Here, (n) is the investment period in years.

Worked example: Suppose you invest Rs. 1,00,000 and its value reaches Rs. 1,30,000 after three years. Your absolute return is 30%, while the CAGR is approximately 9.14% per year.

Calculating rolling returns

Choose a duration, such as three years, and calculate the annualised return for each successive three-year period. You can move the start and end dates forward daily, monthly, or quarterly, depending on the analysis.

For example, a three-year rolling return analysis over ten years can use quarterly intervals. Each calculation covers a three-year period, with the dates advancing by one quarter each time. Comparing the results shows how returns varied across the available periods.

Use rolling returns when you want to examine whether a fund has performed consistently across different periods. They can be useful when comparing schemes that have experienced different market conditions.

Use trailing returns when you want to review performance over a standard timeframe, such as one, three, or five years. They provide a simple point-to-point comparison.

For either measure, compare funds over matching periods and against suitable benchmarks. Consider the fund’s investment strategy, expense ratio, portfolio, and SEBI Riskometer as well. Historical returns are not guarantees of future performance, and neither measure captures every aspect of investment risk.

For broader financial planning, you can also explore SIP investment and compare SIP or lumpsum investment plans.

Rolling returns help you assess a fund’s consistency across overlapping periods, while trailing returns show performance between fixed dates. Using both, alongside a benchmark, risk measures, costs, and portfolio information, gives you a more balanced basis for comparing mutual funds. Neither metric can establish which fund will perform best in the future.
