All sectors in the SPX started the trading day lower, not helped by Walmart's (WMT) post-earnings selling action. Kevin Green still believes a $6,200 SPX is in the crosshairs as a resistance level. He later notes higher moves in natural gas and gold as the index trims all-time highs. As for quantum stocks, Kevin says companies are reaching an "apex" off the back of Microsoft's (MSFT) quantum news.
