The S&P 500 Index has experienced drawdowns 92% of the time since 1950, indicating that for equity investors, market fluctuations are an inherent part of investing. Historical data shows that intra-year drawdowns occur regularly, with a 1% drop happening annually, a 5% decline every 1.1 years on average, a 10% fall every 1.6 years, a 15% drop every 2.5 years, a 20% decline every 4 years, and a 30% drop approximately every decade. Analysts caution that while these statistics are informative, they have limitations due to the unpredictable nature of markets, which can experience extreme downturns more frequently than traditional models suggest. Furthermore, historical trends indicate that after significant declines, the market tends to recover, with notable rebounds following past downturns, such as a 26% increase the year after a 23% drop in 2002 and a 23% rise after a 38% decline in 2008.
