Valuation history
P/E ratio history
The P/E chart uses 674 weekly price points (2013-11-15–2026-10-08); 53 have a basic or diluted P/E ratio. Annual EPS carries forward between fiscal year-ends.
Fiscal-year-end snapshots
1 fiscal-year-end periods with an eligible ratio (2021-12-31–2021-12-31). Most recent: diluted 627.17× and basic 602.08× (fiscal end 2021-12-31; price date 2021-12-31).
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.
