According to Mihir (@RhythmicAnalyst) on Twitter, the S&P 500 has maintained a 16-year uptrend since 2009, with notable recoveries following corrections in 2015 and 2020 (source: @RhythmicAnalyst, May 22, 2025). The index now approaches a significant trend-level resistance, signaling a potential inflection point. For cryptocurrency traders, this critical resistance could impact risk sentiment across global markets, potentially increasing crypto volatility if the S&P 500 experiences a reversal or sustained pullback.
