He received company stock as part of a performance bonus, and he sold shares to cover the related tax liability.Power Integrations stock experienced ups and downs over the past several months due to mixed results. For example, in its fourth quarter earnings report, the company’s sales declined 2% year over year to $103.2 million.In addition, Power Integrations forecasted Q1 revenue to be between $104 million to $109 million. This wide range could result in sales decline compared to the prior year’s $105.5 million if revenue comes in at the low end.That said, over the long term, Power Integrations CEO Jen Lloyd stated, “Our addressable market continues to expand as AI data centers, electrification, grid modernization and other macro trends drive demand.“So while shares are well off the 52-week high of $68.20, now could be a good time to buy. For shareholders, it’s best to wait to sell, since the company could deliver revenue growth thanks to the AI tailwind.About the AuthorRobert "Izzy" Izquierdo is a contributing Motley Fool stock market analyst covering information technology, consumer discretionary, consumer staples, and communication services sectors.
