On June 4, Applied Optoelectronics fell 5.47% in pre-market trading, trading at $173.5/share, with trading volume of $5.77 million. The decline extends a pullback that began the prior session when the stock dropped 8.03%.

On the news front, AAOI had previously surged over 15% across two consecutive trading days after renowned investor Serenity publicly endorsed the stock as a potential next SanDisk and the company's Xinbei factory 800G optical transceiver capacity received production approval from a hyperscale customer. The rapid run-up created significant short-term profit-taking pressure. Meanwhile, Q1 EPS of -$0.12 missed market expectations, and a $600 million ATM equity offering plan continues to weigh on sentiment.

Within the Communication Equipment sector, broad weakness is evident. Among peers, Nokia fell 6.58%, Arista Networks fell 5.76%, Ciena fell 4.56%, and Lumentum fell 4.32%, reflecting sector-wide selling pressure that further dragged on AAOI.
