Why watching option and stock activity matters
On Thursday, 2/11/16, there were some large blocks of IWM (Small Caps) calls throughout the trading session:
>> 39,772 IWM Mar16 97.0 Calls $2.31 SWEEP / OPENING
>> 10,000 IWM Mar16 97.0 Calls $2.53 OPENING Above Ask!
>> 2,913 IWM Fri 2/12 94.0 Calls (Wkly) $1.34 ASKSIDE
However, examining stock activity illustrates that there were large blocks of the common equity being sold close to the same time as the call buying. Without having the full picture in both options and equities one can be mistaken by only following only one side of the trade.
