Applied Optoelectronics (AAOI) experienced a pre-market plunge of 5.44% on Thursday, extending recent losses.
The decline is primarily attributed to significant profit-taking pressure following a cumulative surge of over 15% across two prior trading sessions. This earlier rally was driven by notable investor Serenity publicly endorsing AAOI as a top U.S. photonics pick and the company's Xinbei factory securing production approval from a hyperscale customer for 800G optical transceiver capacity.
Simultaneously, the broader Communication Equipment sector traded lower, reflecting subdued sector sentiment that further weighed on the stock price.
