What Is Return?
Return, in finance, represents the gain or loss on an investment over a specified period, expressed as a percentage of the initial cost. It is a fundamental metric within investment performance, crucial for assessing how well an asset, portfolio, or even an entire market has performed. Return encompasses not only changes in an asset's price but also any income generated, such as dividends from stocks or interest from bonds. Understanding return is essential for investors to evaluate profitability, compare different investment opportunities, and make informed decisions about their financial strategies.
History and Origin
The concept of measuring investment performance and, by extension, return, has evolved significantly with the growth of financial markets. Early forms of return calculation were often simpler, focusing primarily on capital appreciation. However, as financial instruments became more complex and diversified, the need for a comprehensive measure that included all forms of investor gain became apparent. Modern investment theory, particularly since the mid-20th century, has formalized the calculation of total return to provide a complete picture of an investment's aggregate performance. Academic institutions and financial data providers have contributed to standardizing how returns are measured and reported across various asset classes. For example, extensive research has explored the long-term historical returns across major asset classes, reconstructing data over more than a century to provide a deep understanding of wealth accumulation trends.8
Key Takeaways
- Return measures the financial gain or loss on an investment over time.
- Total return includes both price appreciation (or depreciation) and any income generated.
- It is typically expressed as a percentage of the initial investment.
- Analyzing historical return is crucial for evaluating past performance and informing future investment strategy, though past performance does not guarantee future results.
- Return is a key component in assessing investment risk and overall portfolio health.
Formula and Calculation
The most common and comprehensive measure is Total Return, which accounts for both capital appreciation and any income received. The basic formula for total return is:
Where:
- (\text{Ending Value}) = The market value of the investment at the end of the period.
- (\text{Beginning Value}) = The initial market value of the investment at the start of the period.
- (\text{Income}) = Any dividends, interest payments, or other distributions received during the period.
For periods longer than one year, total returns are often annualized to allow for a meaningful comparison across different timeframes. Morningstar, for instance, calculates total return by taking the change in price, adding all income and capital gains distributions, and dividing by the starting price, with reinvestments assumed.7
This formula provides a clear picture of the overall change in an investor's wealth from an asset, incorporating all sources of gain or loss, a key element when considering the time horizon of an investment.
Interpreting the Return
Interpreting return involves understanding its context, primarily the time period over which it is calculated and the type of asset. A positive return indicates a profit, while a negative return signifies a loss. Returns are typically compared against a benchmark or a peer group to assess relative performance. For example, an equity fund's return might be compared to the S&P 500 Historical Data to see if it outperformed the broader market.6
It is also crucial to consider the impact of inflation when interpreting returns. "Real return" adjusts the nominal return for inflation, providing a more accurate picture of the purchasing power gained or lost. Higher returns often come with higher levels of risk, emphasizing the trade-off inherent in financial markets. Investors use return figures, alongside risk metrics, to evaluate if an investment aligns with their financial goals and risk tolerance as part of their broader asset allocation strategy.
Hypothetical Example
Imagine an investor buys 100 shares of Company A at $50 per share, totaling an initial investment of $5,000. Over one year, the company pays a dividend of $1 per share, and the stock price increases to $55 per share.
- Beginning Value: 100 shares * $50/share = $5,000
- Ending Value: 100 shares * $55/share = $5,500
- Income (Dividends): 100 shares * $1/share = $100
Using the Total Return formula:
In this scenario, the investor's total return on the investment for that year is 12%. This includes the capital appreciation from the stock price increase and the income received from dividends.
Practical Applications
Return is a cornerstone metric with widespread practical applications across finance:
- Investment Analysis: Analysts use return to evaluate the historical performance of individual securities, mutual funds, exchange-traded funds (ETFs), and other investment vehicles. This analysis helps investors gauge the effectiveness of a particular investment strategy.
- Portfolio Management: Portfolio managers continuously monitor the return of their portfolio components and the overall portfolio to ensure alignment with client objectives and risk profiles. They use return metrics to rebalance portfolios and make adjustments.
- Financial Planning: Individuals use expected return to project the growth of their savings and investments for future goals, such as retirement planning or purchasing a home. The power of compounding returns over long periods is a key consideration in long-term financial planning.
- Regulatory Compliance: Investment advisors and funds are subject to regulations regarding how they advertise and present performance. The Securities and Exchange Commission (SEC) provides guidance on the presentation of investment performance, including the display of gross and net returns in marketing materials to ensure transparency and prevent misleading claims.5
- Economic Analysis: Aggregate market returns, such as those of major stock indices, serve as indicators of economic growth and investor sentiment. Researchers at institutions like the National Bureau of Economic Research (NBER) analyze long-term return data to understand economic trends and asset pricing.4
Limitations and Criticisms
While return is a vital metric, it has limitations. A primary criticism is that past return does not guarantee future results. Market conditions, economic cycles, and individual company performance are dynamic and can change unexpectedly. A high historical return, therefore, does not inherently mean an investment will continue to perform similarly.
Furthermore, return figures alone do not convey the risk taken to achieve them. Two investments might have the same return, but one might have experienced significantly higher volatility. This necessitates considering risk-adjusted return measures to get a more complete picture. The impact of fees, taxes, and inflation also often needs to be factored in to determine the "real" or "net" return an investor actually experiences. Reporting rules, such as those from the SEC, aim to ensure that performance data is presented clearly and fairly, especially concerning the distinction between gross and net returns.3 Investors should also be wary of "cherry-picking," where only the best-performing periods or investments are highlighted, presenting an incomplete or misleading view of overall performance.
Return vs. Yield
Return and yield are related but distinct financial concepts. Return refers to the total gain or loss on an investment, encompassing both price changes (capital appreciation or depreciation) and any income generated. It represents the overall change in the value of an investment over a specific period.
Yield, on the other hand, specifically measures the income generated by an investment relative to its current price or face value, typically expressed as an annual percentage. For example, a stock's dividend yield is its annual dividend per share divided by its share price, while a bond's yield to maturity considers all future interest payments and the bond's face value relative to its current market price. Yield is a component of total return, but it does not account for changes in the investment's principal value. An investment can have a positive yield but a negative total return if its capital value depreciates significantly.
FAQs
What is a good return on investment?
A "good" return on investment is subjective and depends on various factors, including the investor's risk tolerance, time horizon, and prevailing market conditions. Historically, the stock market has delivered an average annual return of around 8-10% over long periods, but this figure can vary greatly from year to year.2 What is considered good for a high-risk, long-term investment might be unacceptable for a low-risk, short-term one.
How is return different from profit?
Return is typically expressed as a percentage, indicating the rate of gain or loss relative to the initial investment. Profit is an absolute dollar amount representing the positive difference between revenue and expenses, or the selling price and cost basis. While a profit implies a positive return, return provides a standardized way to compare performance across investments of different sizes.
Can return be negative?
Yes, return can be negative. A negative return indicates that the investment has lost value over the specified period. This can occur due to a decrease in the asset's market price, and even if some income was generated, the capital loss may outweigh it, resulting in an overall negative total return.
What is risk-adjusted return?
Risk-adjusted return is a measure that takes into account the level of risk taken to achieve a certain return. It aims to provide a more comprehensive view of an investment's performance by penalizing investments that generate high returns through excessive risk-taking. Common risk-adjusted return metrics include the Sharpe Ratio or Sortino Ratio, which help investors assess the efficiency of their returns.
Why is reinvesting income important for total return?
Reinvesting income, such as dividends or interest, allows those earnings to generate additional returns over time, a process known as compounding. This can significantly boost the overall total return, especially over longer investment periods, as the base upon which future returns are earned continuously grows. Many calculations of total return, especially for mutual funds and ETFs, assume the reinvestment of all distributions.1
