Allegro Microsystems's P/E ratio of 540.37 comes from dividing a price-based measure by a related financial statistic. Changes can come from the stock price moving, the underlying fundamental shifting, or both. Track both the level and the trend — a rising multiple on falling fundamentals is a different story than a rising multiple on rising earnings.
