The Charles Schwab August 2026 STAX saw a dip from July's 4-year high, though as Joe Mazzola explains, investing trends signal more of a rotation as opposed to outright selling. Higher call-buying activity in certain stocks and the QQQ gives Joe confidence in tech's forward momentum. The energy, industrials, and utilities sectors all saw increases in buying activity as well. Joe notes SpaceX (SPCX), Micron (MU), Nvidia (NVDA) and Intel (INTC) as the top net buys for the month. Palantir (PLTR), Microsoft (MSFT), and ServiceNow (NOW) were the biggest net sells.
