Unusual Options Activity: $20M Bet on MU $940 Calls Expiring Oct 14
13,688 contracts traded vs. 14 open interest, about $20.0M in premium.
Traders bought or sold 13,688 MU $940 call contracts expiring Oct 14, about $20.0M in premium, against just 14 contracts of existing open interest (977.7× volume to open interest). That makes it one of the largest unusual options trades in the market in the latest session.
The strike is in the money with MU at $943.86 (-4.6% on the day). Volume above open interest means new positions are being opened, which is why options traders watch these prints closely. Calls gain if the stock rises above the strike before expiration, though big prints can also be hedges.
