Why Is APPLIED OPTOELECTRON (AAOI) Stock Moving Today?

Applied Optoelectronics (NASDAQ:AAOI) shares fell 11.88% to $86.16 on Thursday. The primary driver was a sector-wide pullback in optical networking suppliers as doubts about artificial intelligence infrastructure funding spread through the group. Peers Coherent and Lumentum also declined, with both sliding 7% in the same session.

What Happened

The stock opened at $97.05, a 0.7% gap down from the prior close of $97.78. Trading weakened throughout the day, hitting a session low of $85.93 at 2:00 PM ET. Volume reached 8.3 million shares, which is 0.8 times the three-month daily average. The decline follows a broader trend where optical connectivity stocks have seen significant gains this year, with AAOI up 175% in 2026. However, a 9% pullback in the past month has raised questions about the sustainability of these gains. Cboe data indicates mixed options sentiment, with shares down 3.85% in a related data point.
