On August 6, Applied Optoelectronics fell 6.46% in regular trading, trading at 125.52 USD/share, with turnover of $239 million. The decline comes as investors engage in profit-taking ahead of the company's earnings release scheduled for after-hours today.

The stock had surged sharply over the preceding sessions, driven by reports that the U.S. is drafting an import ban on Chinese data center equipment components, which directly benefits domestic optical communications suppliers like Applied Optoelectronics. The stock gained over 21% on August 4-5 alone on this policy catalyst combined with strong earnings expectations. Market consensus projects quarterly revenue of approximately $190 million, representing year-over-year growth of 80.03%, with adjusted EPS of $0.02.

Today's pullback reflects partial position unwinding by investors locking in gains before the earnings announcement. The broader Communication Equipment sector also faced headwinds, with Arista Networks declining 1.67%, adding additional pressure to the stock.
