Charles Schwab's Joe Mazzola takes investors through the September STAX report. "Sentiment is pretty strong right now" in markets, according to Joe, pointing out significant buying activity in A.I. and A.I.-adjacent stocks. Names like CoreWeave (CRWV) showed a growing risk-on appetite paired with the resurgence on meme stocks like Opendoor (OPEN). Joe believes the data shows a continuing bull run despite economic uncertainty.
