"I would have thought this choppiness would have ended by now," he said, adding: "We're in a really, really good seasonal period. Typically mid-December through the last trading days of the year is traditionally the Santa Claus rally period."

Investors were optimistic about further U.S. interest rate cuts in 2026 after the Fed cut interest rates by 25 basis points on Wednesday, in a 9-3 decision, even though policymakers signalled that it will put further reductions on pause for now. Policymakers have ?expressed concerns about a cooling labor market as well as inflation that remains too high.
