On July 15, Applied Optoelectronics fell 5.97% in regular trading, trading at $119.4/share, with turnover of $134 million. The decline came as the optical communications sector weakened again after a short-lived rebound the previous session.

The sector had rallied sharply on July 9, driven by AI computing infrastructure tailwinds, with AAOI gaining over 9% that day. However, selling pressure emerged on July 10 and July 13 as short-term profit-taking set in. On July 14, the stock bounced over 12% in an oversold rebound—investment bank Stifel had noted that recent selling in AI hardware should be viewed as a valuation reset rather than demand weakness. Today's decline effectively erased the prior session's rebound gains.

Within the Communication Equipment sector, peers also traded lower: Lumentum down 3.21%, Arista Networks down 1.71%, Cisco down 1.64%, Nokia down 1.62%, and Ondas Holdings down 1.02%.

Applied Optoelectronics is an industry-leading fiber-optic networking products supplier, serving cable television, fiber-to-the-home, and data center end markets. In June, the company received a record-breaking equipment order highlighting rapid expansion in AI data center photonics.
