According to The Kobeissi Letter, retail investors pushed their stock market share to a record 36% in late April 2025, as reported by JPMorgan. This level surpasses the 10-year average of 12% by more than three times, with the year-to-date average also elevated at 21%. This significant influx of retail activity is creating heightened volatility and liquidity in traditional markets, which in turn can spill over into the crypto sector as retail traders often diversify between equities and digital assets during periods of increased participation (source: The Kobeissi Letter on Twitter, May 17, 2025; JPMorgan data). Crypto traders should watch for shifting retail sentiment, as surges in equity trading frequently correlate with higher altcoin and Bitcoin volumes, presenting strategic trading opportunities.
