Two AI infrastructure stocks are bucking broader tech-sector weakness today, with Cerebras Systems Inc (NASDAQ:CBRS) and Modine Manufacturing Company (NYSE:MOD) rallying on fresh catalysts. Both are also seeing unusual options activity as well, with traders leaning bullish. CBRS stock is up 7.9% to trade at $105.47, extending yesterday's surge after the AI chipmaker reported better-than-expected third-quarter results and announced a deal with Microsoft (MSFT). Options volume is running at 2.2 times the usual intraday pace, with 102,736 contracts exchanged and positive net option delta volume of roughly 37,000 shares. Despite the recent rebound, CBRS remains down nearly 27% over the past month. MOD is surging 30.1% to trade at $138.
