The S&P 500 is one of the most popular stock indices in the world, representing 500 of the largest U.S.-based companies. Historically, it has delivered an average annual return of around 10% since 1926, making it a go-to investment choice for many. However, as reliable as it may seem, the S&P 500 is not as diversified as some investors believe. Relying solely on it, especially in retirement, can expose your portfolio to significant risks.
One of the best examples of this risk is the "Lost Decade"—a period from 2000 to 2009 where the S&P 500 essentially delivered zero returns. In this article, we’ll analyze this period, compare different investment approaches, and demonstrate why diversification is crucial for retirement planning.

The "Lost Decade" refers to the ten-year period from 2000 to 2009 when the S&P 500 delivered an annualized return of -0.95%. This performance is rare for such a long stretch in the stock market, as historically, investors expect positive returns over extended periods.
Despite the S&P 500 struggling, other sectors of the market performed relatively well during this time. Investments in small-cap stocks, international stocks, and emerging markets yielded positive returns. This highlights an essential investing lesson—diversification can help reduce risk and improve portfolio performance, particularly during periods of stagnation in the U.S. stock market.
While the S&P 500 lagged during the Lost Decade, other asset classes thrived. Here are the annualized returns for each:
These performance differences highlight why investing beyond the S&P 500 is crucial, particularly for retirees who rely on their portfolio for income.
While the S&P 500 underperformed from 2000 to 2009, it rebounded strongly in the following decade, delivering annualized returns of approximately 13.56%. Even though it outperformed many other market segments during this time, a long-term view is necessary. Looking at the entire 20-year period from 2000 to 2019, the S&P 500 still had the lowest overall return compared to more diversified investment approaches.
To understand the importance of diversification, let's examine how three different investment portfolios performed from 2000 to 2019. These portfolios assumed a retiree with a $1 million starting balance, withdrawing $40,000 annually (adjusted for inflation), following the 4% rule.
If you’re approaching retirement, it’s essential to ensure your portfolio is properly diversified. Investing beyond the S&P 500 can help reduce risk, improve returns, and provide a more stable financial future. The lessons from the Lost Decade highlight the importance of a well-balanced investment approach.
