What's a better trading strategy? Learn and focus on a few stocks like what Don Bright advocates or trade many stocks using filters and sorters. Both sides have viable points. If you focus on a few stocks, you learn the in's and out's. You get the feel for the stocks and you'll capture good moves when they come, but on days when your stocks do nothing you'll make nothing. If you focus on a large basket of stocks you'll have many trading opportunities even on dull days, but you'll lose focus and miss out on major moves.
