P/E Ratio = Current Stock Price ÷ Trailing 12-Month (TTM) Diluted EPS (or Market Cap ÷ TTM Net Income). Chartloom divides stock price by trailing twelve-month EPS, calculated by dividing TTM net income by the weighted-average share count from filings. Note: Variations in share-count conventions across data providers may cause slight differences in reported P/E multiples.
Trailing P/E is based on reported GAAP results and is one of the most widely used valuation metrics.
