New month, new Charles Schwab STAX. Joe Mazzola notes a shift in sentiment with investors moving into more ETFs. He believes those investors want to stay exposed while becoming more diversified. That said, Joe points to Nvidia (NVDA), Microsoft (MSFT), and Tesla (TSLA) holding their top spots in the buy category. Broadcom (AVGO), AMD Inc. (AMD), and Netflix (NFLX) were among the stocks Charles Schwab investors sold the most.
