A year of buying ROK
Over the last 70 days ROK closed between $429.61 (August 24, 2026) and $496.01 (June 30, 2026). One hundred dollars put in at the low would be worth $100 today; at the high, $87. The current price $430.44 is above 1 of those 70 daily closes, so a purchase on a random day of that stretch would be in profit 1% of the time — fees aside.
A typical day moves ROK by 2.5%: a $1,000 position swings about $25 a day.
