On June 5, Applied Optoelectronics fell 5.06% in pre-market trading, trading at $193.68/share, with trading volume of $6.28 million. The stock continued its multi-day pullback following a sharp two-day rally of over 15%.

On the news front, the stock had previously surged after well-known investor Serenity publicly endorsed AAOI as the next SanDisk and the company's New Taipei factory secured production approval for 800G optical modules from a hyperscale customer. Short-term profit-taking pressure has been significant since. Additionally, the company's Q1 EPS of -$0.12 missed market expectations, and a $600 million at-the-market equity offering plan continues to weigh on sentiment.

Within the Communication Equipment sector, optical communication stocks declined broadly. Lumentum fell 3.71%, Nokia dropped 3.97%, Ciena lost 2.88%, Arista Networks slid 1.81%, and Cisco dipped 0.53%, reflecting persistently weak sector sentiment that further pressured the stock.
