The Charles Schwab STAX increased slightly to 40.66 from 39.68. Joe Mazzola highlights what's driving the bullish uptick. He mentions that investors bought into Tesla (TSLA) when it dipped in early June, while others steadily bought Amazon (AMZN). Joe labels Palantir (PLTR) as a "retail darling," signaling a return to risk-on trade. However, he adds that investors remain cautions of trade headlines out of Washington.
