Joe Mazzola breaks down July’s STAX report, Charles Schwab’s monthly report on its client behavior. “Clients aren’t really chasing the rally,” Joe observes, becoming “much more measured” than bullish. The STAX’s top 3 bought stocks include Nvidia (NVDA), and top 3 sold include Apple (AAPL) and AMD (AMD). Healthcare and financials saw client interest, with UnitedHealth (UNH) also a top-performing name. He also sees buyers stepping in when the market hits a dip.
