I'm about halfway through reading this investigative report, specifically where CIBC is sufficiently concerned about the trading of Gouveia to alert the IIROC (KK), and all I could think about was whether CIBC initially attempted to recruit Gouveia for their prominant (sic) Algo/HFT program since his volume of trades perfectly fit with their ever-present manipulative strategy.
I'm guessing he turned them down and thus, they turned him in.
