CNBC’s Jim Cramer has a message for investors watching stocks shoot straight up: don’t get greedy. The Mad Money host warned Tuesday that when a stock goes parabolic, the smartest move is often to start selling, not buying more. A parabolic move happens when shares accelerate rapidly, usually fueled by a strong catalyst and a wave of momentum investors chasing gains. But what goes up that fast tends to come down just as quickly, and Cramer said many investors learn that lesson the hard way.
Rather than chasing those dramatic spikes, Cramer recommends looking for what he calls stairstep stocks, which climb more gradually and steadily over time. They might not feel as exciting in the moment, but they offer something the parabolic plays rarely deliver, which is a real chance to lock in profits. As he put it, you don’t actually make money until you sell, and the vast majority of people caught in a parabolic run never let go before it collapses.
The warning is timely. Many stocks tied to artificial intelligence infrastructure and data center construction soared earlier this year only to fall sharply in recent weeks. Sandisk, for instance, has dropped more than 50 percent from its June peak after a massive rally dating back to last year. Cramer pointed to his own Charitable Trust portfolio as proof that trimming positions during a parabolic surge is smarter than trying to pinpoint the exact top. The trust exited its Arm Holdings position in early July after taking profits along the way, and Arm shares have since fallen 44 percent from their record high. The trust also trimmed Corning multiple times in late June before that stock lost more than half its value, including a 12 percent drop on Tuesday despite a solid earnings report.
Cramer’s final piece of advice may be the most counterintuitive for bargain hunters. He cautioned against treating post-parocalyptic declines as automatic buying opportunities, even when a company’s fundamentals remain strong. Once a parabolic rally breaks, selling pressure can linger far longer than logic would suggest. A stock that has already plunged might look cheap on paper, but Cramer noted that existing shareholders are often just looking for an exit, which can keep pushing the price lower. His bottom line is simple enough: don’t be tempted by the wreckage of a broken parabola.
