One Reason to be Careful:
Revenue Spiraling Downwards
A company’s long-term sales performance is one signal of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Western Digital struggled to consistently generate demand over the last five years as its sales dropped at a 8% annual rate. This wasn’t a great result, but there are still things to like about Western Digital. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.
