Valuation history
P/E ratio history
The P/E chart uses 1129 weekly price points (2005-02-25–2026-10-08); 889 have a basic or diluted P/E ratio. Annual EPS carries forward between fiscal year-ends.
Fiscal-year-end snapshots
17 fiscal-year-end periods with an eligible ratio (2008-09-28–2025-09-28). Most recent: diluted 35.84× and basic 35.46× (fiscal end 2025-09-28; price date 2025-09-26).
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.
