I own 90% biotech stocks and in general I'm a longterm investor. I buy often stocks when they are less than a dollar and often sell them when they are 2-4 baggers. My motto for 2015: "Remember to take profit once in a while "!!
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
Day trader, short term opportunist playing volume and volatility. Trade stocks and options normally for 3 days to 2 weeks. I have been trading for about 15 years. I still have a day job and trade on my own ticket. Do as you will.
