About this data

Source: COST's SEC filings (10-K / 10-Q). Annual columns are as-reported fiscal years; quarterly columns are as-reported fiscal quarters (Q4 derived as full-year minus the first three quarters where a company doesn't file a standalone Q4); TTM (quarterly) rolls the trailing four quarters at every quarter end, TTM (yearly) samples that one year apart; balance-sheet rows show the period-end balance. Valuation ratios are sampled as of each period end. View all COST filings on SEC EDGAR → Not investment advice.
