Today's Charles Schwab Big Picture panel turns to the latter half of Wednesday in Mag 7 earnings and the widely-expected interest rate cut from the Fed. Kathy Jones explains why she'll keep a close eye on dissenting views among Fed governors, as they can lead to difficulties in the rate cutting cycle ahead. Joe Mazzola focuses on Mag 7 earnings after the close and makes the case that they need to outperform to continue market momentum.
