Historical data shows S&P 500 declines of 3-15% following 50-day/100-day MA death crosses in 2016, 2018, 2020, 2022, 2023, and 2025. This crossover is a widely watched bearish technical signal, implying momentum shift and potential for a repeat of historical downturns. The pattern suggests a high probability of a near-term market drop, creating a short opportunity. History may not repeat; the signal could be a false positive; the market may have already priced in the weakness; a swift reversal is possible.
