Jim Cramer said the surge in semiconductor stocks could be setting up for a nasty pullback, warning viewers that the market’s parabolic moves were worrisome. He pointed to the Philadelphia Semiconductor Index, which logged 18 straight winning sessions in April and climbed roughly 30% over the month, as evidence that the rally had moved too far, too fast.
That is why investors are searching his name now. In Cramer’s own count, 94 U.S.-listed companies in the chip or AI data center space had gained 50% or more since Mar. 30, including AMD, Marvell Technology and Intel. He said the only time the SOX did better than April 2026 was in February 2000, when the index was in the 1,100 range before later sinking as low as 238.
Cramer was blunt about the setup, but he stopped short of saying a crash was already underway. He said the kind of parabolic moves he was seeing were exactly what worried him, yet he was not quite ready to declare a replay of the dot-com era. That hesitation matters because the warning lands in a market where high-tech names have already become a crowded trade, and other large firms have also viewed them as overextended and due for a decline.
POET Technologies gave that concern a sharper edge. The stock had run from $5 per share to about $15 at its recent peak at the start of April, then fell 47% in a day after news broke that Marvell Technologies would not partner with it. A week earlier, Cramer had dismissed POET on Mad Money as too small and speculative, but after he mentioned it on the show the company had two days with gains of over 20% before the reversal.
That kind of whiplash is what makes the current rally look fragile. Cramer said the steep drop in POET should serve as a cautionary tale for overinflated expectations in the chip sector, and the broader message is that the market has already started to punish the names most exposed to the hottest trade. Whether the Philadelphia Semiconductor Index can keep climbing from here is the question investors will be watching next.
