On June 5, Applied Optoelectronics (AAOI) fell 7.74% in regular trading, trading at $190.04/share, with trading volume of $514 million. The decline extends a sharp pullback driven by multiple headwinds.

On the news front, the stock had previously surged over 15% across two consecutive trading days after prominent investor Serenity publicly endorsed the company — calling it the next SanDisk — and its New Taipei factory secured production approval for 800G optical modules from a hyperscale customer. This rapid gain created significant profit-taking pressure, triggering sustained selling.

Simultaneously, the Communication Equipment sector suffered a broad sell-off, with Nokia down 7.85%, Ciena down 7.03%, Arista Networks down 5.29%, Lumentum down 3.96%, and Cisco down 3.4%, reflecting severely depressed sector sentiment that further dragged on the stock.

Additionally, the company's Q1 earnings reported an EPS loss of $0.12, missing market expectations, while a $600 million ATM equity offering plan continues to weigh on near-term sentiment.
