it is Goldman Sachs using the simple algo trading; so for this particular task the parameter was to sell 1 share at a time into the bid, maybe every 1 or 3 minute and runs from 11am to 1pm, for example.
GS has the algo desk and it is a common practice; we just don't know the reason behind it. They have only been net seller over the last few weeks of relatively small total value.
