COST

Read the COST historical price comparison

Explore Costco (COST) across one month, six months, one year, three years, five years, or ten years when enough closing-price history is available.

Compare the starting close with the ending close over the displayed dates. Price change (%) = (ending close ÷ starting close − 1) × 100. Check the data-through date and use the same available window when comparing another stock or ETF.

Closing-price movement excludes dividends, fees, taxes, and trade execution. It is not a live quote, a total-return account statement, or a prediction. Equity Replay is an educational historical simulator, not a broker or investment adviser.
