Jim Cramer said investors should reduce their exposure to AI chipmaker Cerebras Systems because its current valuation is difficult to justify [1, 2].
This shift in strategy comes as the broader semiconductor sector experiences extreme volatility. Cramer's warning suggests a pivot toward risk management for investors who have seen significant gains during the recent artificial intelligence surge.
Speaking during the CNBC Investing Club Morning Meeting on May 15, 2026 [1], Cramer addressed the stock's performance. The livestream, which aired at 10:20 a.m. ET [1], highlighted the tension between the company's technical potential and its market price. Cramer said that while Cerebras has a compelling AI story and promising technology, the valuation has become difficult to justify [2].
This caution follows a period of rapid growth for the sector. Cramer said that chip stocks have gone parabolic [3]. He previously compared the current market environment to the dot-com era, saying that 2026 is not 1999 — it is worse [4].
The advice to trim the position occurs despite Cerebras being one of the top performers within the Investing Club portfolio [1]. This contradiction reflects a strategy of locking in profits when a stock's price exceeds its fundamental value, regardless of past performance.
Cramer's moves in his own portfolio aim to mitigate losses before a potential market correction. He said that the parabolic nature of the current rally makes the timing of these moves critical [3].
“"Chip stocks have gone parabolic."”
Cramer's recommendation to 'trim' reflects a classic contrarian move in a momentum-driven market. By advising a reduction in holdings of a top-performing asset, he is signaling that the AI-driven rally may have reached a peak where price no longer reflects underlying value. This caution indicates a broader concern that the AI semiconductor sector is entering a phase of unsustainable growth similar to previous speculative bubbles.
