Interactive Broker's Sosnick: 'I can't fight the tape, but I can't embrace it either'

Steve Sosnick, chief market strategist at Interactive Brokers, entered the year expecting the stock market to be down in 2026, and while stocks have overcome the gravity he saw weighing it down, he thinks there is trouble on the horizon. "We've become very detached from basic fundamentals and very much focused on ... betting the longshot, that it's going to come in," Sosnick says in today's Big Interview. "Either we reach an extreme level and grow into it ... or we overshoot the target and have to correct a bit and I hope it's nothing worse than a garden-variety correction." Catherine Yoshimoto, director of product management for the Russell U.S. Indexes at FTSE Russell, discusses the 2026 semi-annual Russell U.S. Indexes Reconstitution, which is underway now and concludes on June 26. The process — which resets the index but also defines the size it takes  for a stock to be large-, small- or micro-cap  is-resetting the bar for large-cap investments at roughly $5.7 billion. That's up nearly 25% from a year ago, reflecting huge gains for the Magnificent Seven stocks (up nearly 50% in size from a year ago) but also broad-based growth across market segments. In the Market Call, Kathy Boyle, president of Chapin Hill Advisors, talks about using ETFs to play defense, leaning into precious metals and commodities and other areas to protect against downside risk that she expects will materialize when the market starts to lose its momentum.
