On May 29, Applied Optoelectronics fell 5.05% in regular trading, trading at $171.12/share, with trading volume of approximately $983 million.

On the news front, the company previously reported Q1 earnings per share of -$0.12, missing market expectations, and the stock has remained under sustained selling pressure since mid-May. Although a late-May announcement that its Xinbei factory secured hyperscale customer production approval for 800G optical modules briefly lifted sentiment, broader sector headwinds have overwhelmed the positive catalyst. On the same session, peer stocks Lumentum fell 0.84% and Ciena declined 1.51%, reflecting persistent weakness across the optical communications sector.

Since May 14, AAOI has experienced significant volatility, plunging from approximately $211 to around $161 — a cumulative decline exceeding 23% — before staging a partial recovery. The current pullback suggests the market remains cautious about near-term profitability despite improving capacity outlook, with 800G monthly production expected to exceed 100,000 units by year-end, representing annualized capacity of over 1.2 million units.
