A year of buying JBL
Over the last 60 days JBL closed between $289.76 (September 30, 2026) and $371.78 (August 13, 2026). One hundred dollars put in at the low would be worth $104 today; at the high, $81. The current price $302.39 is above 15 of those 60 daily closes, so a purchase on a random day of that stretch would be in profit 25% of the time — fees aside.
A typical day moves JBL by 6.4%: a $1,000 position swings about $64 a day.
