I was wondering if there is a logical reason why the stock traded as it did this morning.

There were many small parcels traded at short intervals.
Why would someone sell/buy so many small parcels at short time intervals ?
Would each trade have to pay brokerage ?
What financial benefits are there for doing this ?
If not financial what other benefits are there ?

Below I've included some of the trades of this morning (copied from tradingroom).

Thanks in advance.
