Economist Homkes: 'There are early warning signs to be heads-up about'

Economist Rebecca Homkes, a lecturer at Duke University and London Business School whose consulting practice focuses on the things that influence the thinking of chief executives, says that the valuations of A.I. companies are sky high because investors believe in the transformational technology, but that when that transformation shows up — and investors worry that an industry like software could get pinched in the transformation — investors tend to panic. She sees concerns that the A.I. funding cycle has become so circular that any troubles could unwind the market quickly, so while she is not expecting a recession or a bubble quickly, she does suggest danger signs are visible now.

Carter Braxton Worth, chief executive officer at Worth Charting — known by many as "the Chart Master" on CNBC — brings technical analysis to the Market Call, noting that he doesn't study companies, he studies shares. Worth notes that he currently favors small-cap financials, utilities and energy companies, and he warns of the "bifurcation of technology," where one area of the sector does very well while another one does very poorly, which he considers a sign of potential trouble ahead. This bifurcation is similar -- but with a technical analysis bent -- to Homkes' explanation of the wild market responses to AI stocks.
