CNBC's Jim Cramer warned that semiconductor stocks have gone 'parabolic' and that he has begun selling portions of winning positions like Qnity Electronics to lock in gains. Cramer highlighted the Philadelphia Semiconductor Index's roughly 30% surge in April, noting the only time it performed better was in February 2000 just before the dot-com crash. He pointed to POET Technologies, which cratered 47% in a day after Marvell Technologies said it would not partner with the company, as a cautionary tale for overinflated expectations. Cramer advised investors to stay disciplined, take some profits, and avoid speculative names, while waiting for a more benign pullback before adding to positions like Arm Holdings.
