On August 6, Applied Optoelectronics fell 5.93% in pre-market trading, trading at 121.97 USD/share, with turnover of approximately $28.42 million.

The decline appears driven by profit-taking ahead of the company's quarterly earnings release scheduled for after market close today. The stock had surged sharply over the prior sessions — climbing over 21% on August 5 alone — fueled by reports that the U.S. is drafting an import ban on Chinese data center equipment and strong revenue growth expectations of approximately 80% year-over-year for the upcoming quarter. The pre-market pullback reflects partial position unwinding by investors locking in gains before the earnings announcement.

The broader Communication Equipment sector is also under pressure, amplifying the selling. Within the sector, Ciena fell 3.62%, Ondas Holdings declined 2.59%, Lumentum dropped 2.28%, Arista Networks slipped 1.93%, and Cisco edged down 0.23%.

Applied Optoelectronics is an industry-leading fiber-optic networking product provider, supplying cable television, fiber-to-the-premises, and data center end markets with optical modules, lasers, transceivers, and related equipment.
