Valuation history
P/E ratio history
The P/E chart uses 1129 weekly price points (2005-02-25–2026-10-08); 928 have a basic or diluted P/E ratio. Annual EPS carries forward between fiscal year-ends.
Fiscal-year-end snapshots
18 fiscal-year-end periods with an eligible ratio (2008-12-31–2025-12-31). Most recent: diluted 20.19× and basic 20.19× (fiscal end 2025-12-31; price date 2025-12-26).
Annual P/E = fiscal-year-end closing price ÷ reported annual EPS. It is a historical annual ratio, not TTM or forward P/E. Zero or negative EPS and missing eligible prices produce no ratio. Why we use annual data.
