10 Big Names Ending January With Explosive Gains

5. Applied Optoelectronics Inc. (NASDAQ:AAOI)

Applied Optoelectronics surged to a new record high on Friday, reflecting strong investor confidence in its business despite the absence of fresh developments.

At intra-day trading, the stock jumped to its highest price of $48.31 before paring gains to finish the session just up by 10.21 percent at $43.61 apiece.

The rally was supported by a research firm’s optimistic outlook for Applied Optoelectronics Inc. (NASDAQ:AAOI) earlier in the week, saying that its laser transceivers are critical to the AI revolution “because they overcome the speed and bandwidth limitations of traditional copper cables, making them valuable for enabling the massive, low-latency data flow required from training and operating large AI models.”

“Additionally, with copper prices rising currently, these fiber optic cables are even more valuable,” the research firm said.

Earlier, Applied Optoelectronics Inc. (NASDAQ:AAOI) unveiled a new 400-milliwatt narrow-line-width pump laser designed to meet growing demand for silicon photonics and co-packaged optics (CPO) in AI data centers.

The new product is capable of addressing situations where lasers with broader line widths or higher noise figures limit performance. It can source directly into semiconductor chip-scale systems to provide hyperscalers with a robust, high-performance light source for CPO, silicon photonics, and other applications that demand precision and power from a single, stable wavelength.
