The pitfalls of comparing portfolio returns

Investing with Confidence: Cutting Through the Noise of Portfolio Comparisons
Investing can be a daunting experience, filled with uncertainty and self-doubt. You carefully select a portfolio, deposit your money, and then wait for the magic of compound growth to take hold. However, with historical stock returns indicating that it takes roughly a decade for every dollar invested to double, it's natural to wonder if you're making the right choices with your money. The temptation to constantly check your portfolio returns and compare them to others can be overwhelming, but it's essential to approach these comparisons with a clear understanding of the variables at play.
The Importance of Apples-to-Apples Comparisons
When evaluating the performance of your portfolio, it's crucial to make apples-to-apples comparisons. This means considering the composition of the portfolios, including their fees and tax treatments. For instance, our Core portfolio has delivered an average annual return of approximately 10% after fees, based on the actual returns of our customers. While this figure may seem impressive, its value depends on the context in which it's compared. Stock indexes like the S&P 500 and Dow Jones often dominate the news, but they're not comprehensive benchmarks, as they exclude bonds and international markets. Our globally-diversified portfolios, on the other hand, are designed to provide a smoother investing journey by spreading investments across different asset classes and geographic regions.
The Nuances of Diversification
Not all diversification strategies are created equal. Even portfolios with similar stock-to-bond ratios can take different paths to achieve their goals, influenced by factors such as tax optimization, market timing, and fund fees. Some investors may try to compare providers by investing small amounts with each and then comparing the balances after a few months. However, this approach may not provide a meaningful comparison. A more effective way to evaluate your portfolio's performance is to compare it to relevant benchmarks, such as the ACWI and AGG ETFs, which track a broad range of stocks and bonds. By using these benchmarks, you can gain a better understanding of your portfolio's performance and make more informed decisions about your investments.
Putting Your Performance in Perspective
Comparing your investing returns to others can be a natural impulse, but it's essential to do so in a way that avoids common pitfalls. This means avoiding comparisons between globally-diversified portfolios and those with a narrow focus, as well as cherry-picking small sample sizes instead of considering longer-term track records. To help you navigate these challenges, we provide tools and resources, such as the Betterment app, which allows you to compare your portfolio's performance to relevant benchmarks and track your progress over time. By taking a thoughtful and informed approach to portfolio comparisons, you can invest with confidence and make the most of your money.

Q#1: What is the typical timeframe for invested money to double in value through compound growth?
Answer: According to historical stock returns, it takes roughly a decade for every dollar invested to double in value. This timeframe highlights the importance of patience and long-term perspective in investing. It's essential to avoid constant checking and comparing of portfolio returns.
Q#2: Why is it crucial to make apples-to-apples comparisons when evaluating portfolio performance?
Answer: Making apples-to-apples comparisons is vital because it considers the composition of the portfolios, including their fees and tax treatments. This ensures a fair and accurate assessment of portfolio performance, rather than comparing dissimilar portfolios. It helps investors understand the true value of their investments.
Q#3: What are the limitations of using stock indexes like the S&P 500 and Dow Jones as benchmarks for portfolio performance?
Answer: Stock indexes like the S&P 500 and Dow Jones are not comprehensive benchmarks because they exclude bonds and international markets. They do not provide a complete picture of the investment landscape, making them inadequate for comparing the performance of globally-diversified portfolios. A more nuanced approach is needed to evaluate portfolio performance.
Q#4: How can different diversification strategies impact portfolio performance, even if they have similar stock-to-bond ratios?
Answer: Different diversification strategies can take varying paths to achieve their goals, influenced by factors such as tax optimization, market timing, and fund fees. These factors can significantly impact portfolio performance, even if the stock-to-bond ratios appear similar. Investors should consider these nuances when evaluating their portfolios.
Q#5: Why is investing small amounts with multiple providers and comparing balances after a few months not a reliable method for comparing portfolio performance?
Answer: This approach is not reliable because it does not provide a meaningful comparison due to the short timeframe and potential differences in portfolio composition. A more comprehensive evaluation of portfolio performance requires a longer-term perspective and consideration of various factors, including fees, taxes, and diversification strategies.
