It's called adverse selection. You don't want to be on the other side of an order from an informed trader, because the market is moving against you in the short run. In the longer run, if the big fund is more often correct than not, then you are also more likely to have made a losing trade. HFTs care mostly about the effect on the market today, so they probably don't care whether the information is correct or not, they just want to get out of the way of big moves. |
