P/E ratio history
P/E at every stored weekly price, using the latest annual EPS by fiscal-period end. Annual EPS is carried forward; this is not TTM or forward P/E. P/E history calculation and limitations.
Both charts use the same weekly price dates and synchronized time ranges. Each P/E point divides that week’s close by the most recent annual EPS at or before that date; it is not interpolated. Adjusted-close ratios are approximations; later filings and restatements make this retrospective. Reference lines are comparisons, not price targets.
