Active managers have generally not outperformed the market in either bull or bear markets. During the 2008 financial crisis, actively managed funds underperformed the S&P 500 index by an average of 1.67% on average. Studies from 2008-2012 also found that the majority of active managers failed to outperform their benchmarks across various market categories. While markets have historically delivered positive returns, it is typically a small group of top-performing stocks that drive those returns, making it difficult for managers to consistently pick winners. Diversification can help reduce risk and volatility compared to investing only in stocks, as seen during the 1973-1976 and 2007-2011 periods where a diversified portfolio lost less than a pure stock portfolio.
