Retail investors, who have been one of the most reliable bottom-fishing forces in the U.S. stock market in recent years, appear to be growing less willing to enter the market as risks accumulate. According to data from Vanda Research, this group recorded a net sell-off of individual stocks for the first time since November 2023 on Monday, offloading $20.6 million worth of equities. The sell-off occurred as the S&P 500 rebounded following former President Donald Trump's decision to ease his threat of bombing Iran's energy infrastructure—a backdrop that may suggest even a broad market recovery is no longer sparking the same level of enthusiasm among retail traders.

This pullback has been building for some time. Vanda Research noted that demand from this investor segment has been steadily weakening as Middle East tensions persist, describing the trend since early March as a gradual decline in retail participation. Although retail investors resumed buying on Tuesday, purchasing a net $262.3 million in stocks by 12:50 PM ET while the S&P 500 traded slightly lower, the benchmark index remains down nearly 5% for the month. At the same time, Vanda indicated that systematic deleveraging has been underway, while buying from long-only funds and hedge funds remains only moderate.

Other signs also point to a potential erosion in confidence. Citadel Securities' gauge of retail risk appetite has fallen significantly from its February peak, fueling concerns that one of the market's key support pillars may be weakening. Throughout the three-year bull market, retail buying power has helped stabilize the market during periods of volatility. Data from JPMorgan shows that retail investors set a record last year, with inflows nearly double the five-year average. That total was 17% higher than the previous record set in 2021 and nearly 60% above the level seen in 2024, which could make the recent cooling in participation all the more notable for investors watching how much support remains for U.S. equities.
