50 Years of S&P 500 History Favors Buy-and-Hold Index Funds Over Market Timing

3 articles · Updated · Yahoo Finance · Sep 5

Summary

  • Fifty years of market history show investors who held S&P 500 index funds through downturns came out ahead, despite repeated bull-and-bear swings.
  • That long-run edge comes from avoiding market timing, which the report says is difficult to execute consistently and often driven by the urges that hurt returns.
  • Warren Buffett’s preferred approach for most investors is to keep buying broad S&P 500 funds such as SPY or VOO at regular intervals rather than reacting to short-term volatility.
  • The broader takeaway is that downturns do not break the long-term case for index investing; sticking to a fixed plan and dollar-cost averaging remain the recommended response.
