Great suggestion. My philosophy is this. I want to move the needle. I like violent moves. However at the same time, I want to limit my risk. I do this by my scans and vehicle selection. I teach very specific chart styles and technical analysis and we are extremely consistent.
So having said that, I am not a big fan of huge diversification. I like splitting my capital up into only 4 to 6 stocks maximum. So it is not unheard for me to have minimally a 25% capital stake in a play. I play no pennies, story stocks, pump n dumps, low float trade by appointment stocks. I trade growth stocks that are market leaders and fundamentally very strong.
