Cumulative return: A fundamental investment metric
Cumulative return, often referred to as “cumulative total return,” is a key metric used in the world of finance and investments. It quantifies the total gain or loss an investment has experienced over a specified period, regardless of the time involved. In essence, it calculates the aggregate return on an investment.
Calculating cumulative return
The formula for calculating cumulative return is relatively straightforward:
Cumulative Return = ((Current Price of Security) – (Original Price of Security)) / (Original Price of Security)
This result is expressed as a percentage. To put it simply, it measures how much an investment has grown or shrunk relative to its original value.
Understanding cumulative return
Cumulative return provides investors with a comprehensive view of how an investment has performed over time. This metric is particularly useful for assets that do not generate interest or dividends, such as precious metals and certain growth stocks.
For these types of investments, you can calculate the cumulative return using the raw closing price. This approach is suitable because these assets do not issue dividends. It’s a straightforward way to measure the total change in value over time.
On the other hand, assets like interest-bearing bonds and dividend-paying stocks require a slightly more complex calculation. To account for the impact of interest, dividends, stock splits, and other changes, the adjusted closing price is used as the original price of the security.
The impact of dividends and capital gains
Reinvesting dividends or capital gains can have a significant effect on an investment’s cumulative return. When these distributions are reinvested, they contribute to the overall growth of the investment. Therefore, it’s important to consider whether an investment includes these reinvested returns in its cumulative return figures.
For investors in mutual funds, there’s an additional complexity. Mutual funds may distribute capital gains to their shareholders at the end of a calendar year. These distributions are profits made by the fund’s portfolio managers when they sell holdings. Shareholders can choose to reinvest these capital gains, affecting how cumulative returns are calculated.
Mutual funds and ETFs
Mutual funds and exchange-traded funds (ETFs) often present their performance using cumulative return graphs, like the mountain graph you might have seen. However, it’s essential to confirm whether these figures include interest or dividends. The materials accompanying these illustrations should provide this information.
The distinction lies in how these payouts are counted. They can be reinvested in the fund or simply added as raw dollars when calculating the cumulative return. This difference can significantly affect the reported performance.
Special considerations
Comparing investments
One limitation of cumulative return is that it typically grows over time, making older investments seem more impressive. Therefore, it’s not an ideal metric for comparing investments unless they started at the same time. When assessing the performance of different investments, investors often use compound return, which is annualized and takes into account the impact of fees and expenses over time.
Taxes and cumulative returns
Taxes can play a substantial role in reducing cumulative returns for most investments unless they are held in tax-advantaged accounts. The tax treatment of different types of investments varies.
For instance, bonds often face unfavorable tax treatment of interest payments, reducing cumulative returns. However, municipal bonds are typically tax-exempt, requiring fewer adjustments to their cumulative return figures.
Long-term stock investments enjoy the advantage of lower capital gains tax rates, which are usually straightforward to factor into cumulative returns. However, the tax treatment of dividends is more complex and can significantly influence cumulative returns, especially when funds reinvest dividends.
Compound return vs. cumulative return
In addition to cumulative return, investors often encounter compound return figures. Unlike cumulative return, compound return is an annualized metric. While cumulative returns may seem more impressive due to their non-annualized nature, they often do not account for the effect of annual expenses on investors’ returns.
These expenses can include fund expense ratios, interest on loans, and management fees. When calculated cumulatively, these fees can substantially impact the cumulative return figures reported to investors.
Example of cumulative return
Let’s consider an example to illustrate cumulative return. Suppose you invested $10,000 in XYZ Widgets Company’s stock over a ten-year period, and it has grown to $48,000. If you did not incur taxes and did not reinvest dividends, your cumulative return would be 380%. This means your investment has grown by 380% relative to its original value.
Calculating cumulative return with examples
Understanding cumulative return is best achieved through practical examples. Let’s explore two hypothetical scenarios to illustrate how to calculate cumulative return.
Example 1: Cumulative return for a stock investment
Suppose you invested $5,000 in Company X’s stock on January 1, 2020. After a year, on December 31, 2020, the value of your investment had grown to $6,500. To calculate the cumulative return, you can use the formula mentioned earlier:
Cumulative Return = ((Current Price of Security) – (Original Price of Security)) / (Original Price of Security)
In this case:
– Original Price of Security = $5,000
– Current Price of Security = $6,500
– Original Price of Security = $5,000
– Current Price of Security = $6,500
So, the cumulative return would be:
((6,500 – 5,000) / 5,000) = 0.3
This means your investment in Company X’s stock generated a cumulative return of 30% over the one-year period.
Example 2: Cumulative return for a mutual fund
Let’s consider a scenario where you invested $10,000 in a mutual fund on January 1, 2019. By December 31, 2022, your investment had grown to $12,000. During this period, the fund distributed capital gains of $500, which you chose to reinvest.
To calculate the cumulative return, you need to account for both the capital gains distribution and the reinvestment:
– Original Price of Security = $10,000
– Current Price of Security = $12,000
– Current Price of Security = $12,000
Now, add the reinvested capital gains:
– Reinvested Capital Gains = $500
Your cumulative return calculation is as follows:
((12,000 + 500 – 10,000) / 10,000) = 0.25
In this case, your investment in the mutual fund generated a cumulative return of 25% over the four-year period, accounting for reinvested capital gains.
Cumulative return vs. total return
It’s important to distinguish cumulative return from another commonly used metric in investment analysis: total return.
Total return is a more comprehensive metric as it factors in all sources of returns, including price appreciation, dividends, interest, and capital gains. Cumulative return, as we discussed earlier, focuses on the price change, excluding these additional sources.
While cumulative return provides a simplified view of an investment’s growth or decline, total return offers a more accurate representation of the overall performance, especially when evaluating income-generating investments like dividend stocks or bonds.
Real-world applications of cumulative return
Cumulative return is not limited to theoretical calculations. It has real-world applications, and investors frequently use it to assess the performance of various investments. Let’s explore some practical scenarios where cumulative return is useful:
1. Evaluating mutual fund performance
Investors often rely on cumulative returns when assessing mutual funds. A mutual fund’s historical cumulative return can reveal how well the fund has performed over a specific timeframe. However, as mentioned earlier, it’s essential to consider whether this metric includes reinvested dividends and capital gains.
2. Comparing investment portfolios
For those with diversified investment portfolios, calculating the cumulative return for each asset can help in assessing which investments have been the most profitable. It allows investors to identify where their money has grown and where it might be lagging.
3. Historical analysis
Investors and financial analysts use cumulative return for historical analysis. By examining how different assets have performed over extended periods, they can identify trends, volatility, and potential opportunities.
4. Setting investment goals
Cumulative return can be a crucial factor when setting investment goals. Knowing the historical performance of an asset or portfolio can guide investors in setting realistic return expectations and timeframes.
Conclusion
Cumulative return is a fundamental metric for assessing investment performance, providing a straightforward way to measure an investment’s growth or decline over a specified period. While it offers valuable insights, investors should be aware of its limitations, especially when comparing investments launched at different times. To make informed investment decisions, consider using cumulative return in conjunction with other metrics, like total return, and account for factors such as taxes, expenses, and dividend reinvestment.
In the world of finance, understanding and using cumulative returns effectively can be a powerful tool for investors. Whether you are evaluating mutual funds, managing a diversified portfolio, or setting investment goals, the knowledge of cumulative return can help you make informed financial decisions.
Frequently asked questions
What is the primary difference between cumulative return and compound return?
Cumulative return provides an aggregate view of an investment’s performance over a specific period, measuring the change in value without considering annualization. In contrast, compound return is an annualized metric that factors in the impact of annual expenses on an investment’s returns.
How can I calculate the cumulative return for investments that issue dividends or generate interest?
For investments like dividend-paying stocks or interest-bearing bonds, you should use the adjusted closing price as the original price of the security to account for interest, dividends, stock splits, and other changes. This provides a more accurate representation of the cumulative return.
Does cumulative return include the impact of taxes on investment returns?
Cumulative return figures do not inherently account for taxes. Taxes can significantly reduce cumulative returns for most investments unless they are held in tax-advantaged accounts. The tax treatment of different investment types, such as bonds and stocks, varies and can affect your returns.
