A year of buying COST
Over the last 48 days COST closed between $914.39 (July 11, 2026) and $972.50 (July 29, 2026). One hundred dollars put in at the low would be worth $106 today; at the high, $99. The current price $967.55 is above 45 of those 48 daily closes, so a purchase on a random day of that stretch would be in profit 94% of the time — fees aside.
A typical day moves COST by 1.7%: a $1,000 position swings about $17 a day.
