While it might not be a household name, Applied Optoelectronics (AAOI) easily ranks among the top performers this year. Since the January opener, AAOI stock has gained 220%, an unsurprising figure thanks to its core business of fiber-optic networking products. Because AI data centers require massive amounts of data to be moved at ultra-high speeds between thousands of graphics processing units, Applied has witnessed a surge in demand.
Unfortunately, this rally is also a double-edged sword. One could make the argument that a good deal of the positive catalysts have already been baked into the AAOI stock price. Further, there are supply chain constraints and key component shortages that have tempered upside. In addition, financial concerns, such as dilutive equity offerings, widening GAAP losses and valuation premiums raise serious questions.
