According to The Kobeissi Letter, the S&P 500 has surged 13.7% over the last 21 trading sessions, marking its strongest 21-day performance since 2020, when a 25% gain was recorded (source: @KobeissiLetter, May 9, 2025). Only five other periods this century have witnessed stronger 21-day gains, highlighting the exceptional nature of this recovery. For crypto traders, such historic equity market rallies often signal increased risk appetite, which can translate into higher flows into Bitcoin and altcoins as investors seek diversified returns. Traders should monitor how this bullish momentum in traditional markets could fuel renewed crypto price action and potentially trigger short-term volatility across major digital assets.
