Duke Energy Sees 'Extremely Unusual' Options Action

More than 33,000 calls traded at the April 12.50 strike against open interest of just 784 contracts by mid-afternoon Thursday, according to OptionMonster's tracking systems. The huge turnover is more than 15 times the average daily volume.

DUK stock ended Thursday down 3 percent to $12.04, having fallen from $16 in just the last month. (The shares gained 1.66 percent as of this writing Friday.) Traders may believe that Duke and other energy names are approaching a bottom at these levels.
