On October 7, Credo Technology Group Holding Ltd fell 5.16% in regular trading, trading at $209.4751 per share with a turnover of $2.3 billion.

The decline was driven by broad-based weakness across the optical communication and storage sectors. Astera Labs fell more than 4%, Corning more than 3%, and SK Hynix, Micron Technology, Seagate Technology, and Western Digital each fell more than 2%, creating significant sector-wide drag.

Market sentiment had already turned cautious following a wave of insider selling by Credo executives and bearish signals in the options market. Recent Form 4 filings showed Chief Operating Officer Lam Yat Tung and Chief Technology Officer Cheng Chi Fung executing multiple share sales through 10b5-1 plans. While Nomura's expert meeting highlighted that the 1.6T optical module DSP supply gap may persist until at least the second half of 2027, supporting long-term demand, short-term capital flows are repricing the stock amid sector rotation and positioning adjustments.
