What Interactive Brokers’ Steve Sosnick Is Saying About Today’s Market Momentum

When you flip on the news and hear the chatter about a market that’s suddenly “on fire,” it’s easy to feel a little lost. That’s why many traders tune in to Steve Sosnick, co‑CEO of Interactive Brokers, for a clear‑cut view that cuts through the hype.

In a recent CNBC interview, Sosnick started by acknowledging the obvious: equity markets have been churning at a pace we haven’t seen in years. "The volume is up, the volatility is up, and the price moves are just… bigger," he said, his tone a mix of excitement and caution.

He then walked us through the three main drivers behind this surge. First, a flood of retail investors who, armed with low‑cost platforms, are trading more aggressively than ever. Second, institutional money that’s shifting between asset classes as yield curves flatten, looking for pockets of return. And third, the ever‑present macro backdrop—interest‑rate expectations, geopolitical jitters, and a surprisingly resilient jobs market.

What struck many listeners was how Sosnick framed the “momentum” narrative. Rather than painting it as a one‑way street, he described it as a “feedback loop.” Higher volume pushes prices, price moves attract more attention, and that attention fuels another round of trading. It’s a cycle that can amplify both upside and downside, depending on which way the pendulum swings.

He didn’t shy away from the risks, either. "When you see 10‑day moving averages crossing over and breaching key resistance levels, it can be tempting to jump in," he warned, "but remember that rapid reversals are equally possible, especially when liquidity thins out.”

For those wondering how to navigate this environment, Sosnick offered two practical tips. First, keep an eye on order‑book depth. A healthy order book can cushion sharp moves, while a thin one may signal a looming squeeze. Second, diversify across asset classes. “Don’t put all your eggs in one basket when the basket itself might be wobbling,” he quipped.

Finally, Sosnick highlighted Interactive Brokers’ own data tools, urging traders to use real‑time analytics rather than relying on lagging indicators. “If you can watch the flow as it happens, you’re better positioned to make informed decisions,” he concluded.

In short, the market’s current momentum is a mixed bag—full of opportunity, but also fraught with volatility. As Sosnick reminded us, staying disciplined, watching the data, and keeping a healthy dose of skepticism may be the best way to ride the wave without getting wiped out.
