CNBC senior markets commentator Michael Santoli discussed the Dow approaching a record close above 49,000. He noted the advance was narrow, driven by Goldman Sachs and Caterpillar, but said the market still favors the cyclical trade, with transports and banks strong. He also flagged a potential rotation back into mega-cap growth and tech, saying the earnings broadening thesis lacks near-term fundamental support. He described AI trade conviction as narrow, centered on Alphabet or Meta, while Microsoft has lacked traction.
