Costco (COST) has touched its pre-ex close within 30 trading days in 100% of the last 20 ex-dividend events, with a median time-to-touch of 1 trading day (limit-order recovery basis). The dividend is below the typical daily price swing (signal-to-noise 0.15), meaning ordinary day-to-day noise can easily exceed the dividend itself.
Versus its sector, COST sits roughly in line with the Consumer Defensive sector benchmark of 95%. The sector median time-to-touch is 1 trading day, matching the peer pace.
Historical base rates are not predictions; transaction costs, slippage, and ordinary-income tax on short holding periods can materially reduce realized profit. The next ex-dividend date is estimated at Jul 31, 2026 (±4 days), based on the historical pattern; the company has not yet declared a dividend.

COST Dividend Capture Backtest Simulator
Replay every historical COST ex-dividend with two exit strategies: a GTC limit-order at the pre-ex close, or hold for N days and exit at MOC. Pick the window and quarter filter that matches your plan.
Sell back at the pre-ex close on the first intraday touch within the window. If it never touches, exit at MOC after the window expires (stop-loss).
Figures are gross — before tax, commissions, and slippage. Percents are per-event return on capital at entry (pre-ex close).
