Charles Schwab Corp. CEO Rick Wurster said the firm proactively called thousands of retail-investing customers in April who were close to triggering margin calls. The outreach came as market volatility increased amid stock declines linked to President Donald Trump's ongoing trade war. Wurster noted that retail investors have begun to slightly reduce risk-taking following the market turmoil in April. Despite this, retail investors collectively purchased $40 billion in equities during the month. Schwab's James Kostulias reported no panic selling, higher client engagement, and noted that retail investors are gravitating towards options trading. Market analysts observed that persistent buying by retail investors helped support the stock market during April's downturn, even as overall sentiment remained cautious.
