I have 20 years of experience in trading. I also have a extensive experience with drug development. I combine technical analysis, valuation of the company and the upcoming short term catalysts before trading. I will set a target price and very tight stop loss limits. I am an active trader and usually sell and jump in again in the same stock until it hits the target price. I like to take my profit after the little runs that the stocks have. It is a more conservative and profitable approach.
