Earnings per share allocates net income to each share of common stock. Diluted EPS includes potentially dilutive securities. Trailing twelve-month (TTM) EPS sums the last four reported quarters when the taxonomy supports it.
EPS is the denominator for P/E and a core earnings-history lens. Comparing EPS across companies still requires the same form, fiscal calendar, and awareness of one-time items.
Stock research pages pull diluted EPS points from SEC EDGAR XBRL companyfacts. Charts and tables cite the filing end dates; gaps stay empty.
