IBKR's Sosnick expects stock market's win streak to end in 2026

Steve Sosnick, chief market strategist at Interactive Brokers, is a market veteran who wasn't allowed to make annual forecasts until this year, and he's starting with an outlier, calling for the Standard & Poor's 500 to lose about 7% in 2026. Sosnick says a key issue for the market is investor expectations which are now so high that "it's hard to outpace that." Sosnick doesn't think the market is going in the tank, but he says that if investors see it struggle and lose some of their "buy-the-dips" nerve, it will create headwinds that will be hard to overcome.

Travis Prentice, chief investment officer at Informed Momentum, brings his stylized investment methodology — which tries to find the stocks that are outperforming, but that also represent businesses that are improving — to the Market Call, and talks about where he is "finding the mo" now.

Todd Rosenbluth, head of research at VettaFi, reviews the year in exchange-traded funds, from the growth in the industry and the action in new funds to the emergence — thanks to new rules — of ETF share classes for established funds, a change that could be the defining story in the industry in 2026.
