Unusual Options Activity: $15M Bet on MSFT $550 Calls Expiring Nov 13
9,494 contracts traded vs. 7,357 open interest, about $15.3M in premium.
Traders bought or sold 9,494 MSFT $550 call contracts expiring Nov 13, about $15.3M in premium, against just 7,357 contracts of existing open interest (1.3× volume to open interest). That makes it one of the largest unusual options trades in the market in the latest session.
The strike is out of the money with MSFT at $541.15 (+1.1% 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.
