A year of buying COST
Over the last 95 days COST closed between $895.50 (September 17, 2026) and $972.50 (July 29, 2026). One hundred dollars put in at the low would be worth $106 today; at the high, $97. The current price $946.28 is above 60 of those 95 daily closes, so a purchase on a random day of that stretch would be in profit 63% of the time — fees aside.
A typical day moves COST by 1.2%: a $1,000 position swings about $12 a day.
