TSMC's (TSM) latest earnings is "raising the bar" for A.I. across the board, says Charles Schwab's Joe Mazzola.

Joe also talks about market optimism from retail investors seen in a boost of options call-side activity. However, he says market performance hinges on the SPX holding a key support level.
