Joe Saluzzi has been worrying for some time about High Frequency Trading (HFT). Here, courtesy of Jesse’s Café Américain, is Saluzzi talking abiout the subject again. My understanding is that the HFTs don’t add liquidity and can give us a whopping headache if they stop trading or hit bids in some news event. Saluzzi’s been bearish for some time and thinks the market has lost all connection between price and value.
