That's exactly the method Cramer talked about in that old interview I posted not too long ago....basically how a Hedge Fund or similar type player will try to push a stock around by pushing a lot of small sell orders through various houses to create the impression of a broad based sell off.
I just found the 4 bypass trades (code W) all with the same buyer to be interesting....and given that they indicate an iceberg order, that perhaps they're signifying a lot more demand than the buyers is willing to show.
