Bear, bull, long, short... It doesn't matter which way I'm going with a stock, I'm just here to make money. If I mess up, well that' my fault. The most important thing in this game is you will never win all the time. Keep a hard head and get burnt.
I invest in companies with strong fundamentals which are also significantly undervalued, presenting a good margin of safety. I write extensively about my ideas and investment strategies on my blog at Soberstocks.com
