New York, January 31, 2026, 09:32 EST — Market closed.
- Shares closed Friday up 10.2% at $43.61, on roughly 12 million shares changing hands.
- A Form 4 filing revealed an insider sale carried out through a pre-arranged trading plan.
- Attention shifts to the upcoming earnings report in late February for insight into demand and margins.
Applied Optoelectronics shares jumped 10.2% to $43.61 on Friday, wrapping up another choppy week for the stock. With U.S. markets closed Saturday, investors will be watching closely to see if the momentum continues when trading restarts Monday, Feb. 2. Roughly 12 million shares traded hands.
The company sells optical transceivers and components that transmit data across fiber networks, serving clients from cloud data centers to cable broadband operators. Traders often classify the stock as part of the AI infrastructure space, given its newer “400G” and “800G” products support 400- and 800-gigabit-per-second speeds inside major data centers.
That’s key today since smaller suppliers linked to data-center projects often move sharply on shifts in sentiment and positioning, beyond just the news. The upcoming session will reveal if Friday’s rebound marks a fresh start or just another twist in this volatile tape.
Shares in optics-related firms showed a mixed bag in the session. Lumentum climbed roughly 2.8%, but Coherent dropped near 1.8%, and Fabrinet slipped about 1.4%.
A filing with the U.S. Securities and Exchange Commission revealed that David C. Kuo, the company’s chief legal officer, sold 12,000 shares on Jan. 28 at a weighted average price of $45.055. According to the form, the sale was executed under a Rule 10b5-1 plan, a pre-arranged trading strategy aimed at addressing insider trading concerns around material non-public information. After the sale, Kuo still directly held 114,636 shares, the filing noted.
Friday’s rally came on the heels of a solid January, with the stock climbing roughly 25% this month, the American Association of Individual Investors reported. Shares fluctuated between $40.75 and $48.31 on Friday. The group also pointed out that the company’s trailing earnings remain negative, rendering the usual price-to-earnings ratio irrelevant.
The longer-term trend points to a shift toward higher-speed optics for AI clusters. On Dec. 10, the company announced its first volume order for 800G data-center transceivers from a “major hyperscale customer,” industry code for a large cloud provider. “We are pleased to receive our first volume order for our 800G products,” said Dr. Thompson Lin, noting confidence that its automated production lines can handle large shipments. Stefan Murry added that the same customer had purchased nearly $22 million worth of the company’s 400G transceivers this year. GlobeNewswire
Zacks Equity Research noted this week that demand in the cable television market, or CATV, plus gains in data-center revenue have bolstered the stock, helped by the rollout of 400G and 800G products. In their latest note on Nasdaq, Zacks forecasted a quarterly loss of 12 cents per share on $134.34 million in revenue for the upcoming report.
The timing for the next report is still unclear. Nasdaq’s earnings page lists no confirmed date for the company, leaving traders on edge for any updates or scheduling announcements in the coming week.
But here’s the rub. The stock’s volatile swings work both ways, and a rapid surge can reverse just as fast if demand dips or if investors view insider selling—even when planned—as a cue to cash out.
MarketBeat, known for tracking earnings calendars, projects the company will release its fourth-quarter results on Feb. 25 after the market close, followed by a conference call the next day, Feb. 26. This late-February report stands as the next significant trigger for the rally’s momentum, particularly for insights into 800G shipments and short-term profit outlook.
