Long short quants make bets each day on thousands of stocks, hoping they can be right 55% on each bet. That’s how they make money. When you make thousands of bets simultaneously and even though each has a tiny edge, you can print money everyday. In Canadian stocks, there’s only about 200-400 or so liquid stocks that quant can trade in size daily. The sharpe ratio will be quite low and so will be kept at a very small size. There is also less data to generate alphas (news, analyst coverage, social media etc..). In US, quant trades up to 3000 stocks daily.
