There is nothing like a Pro in stock market. If there was a definite formula to make money, we can wipe out poverty! U can make money only on long term... short term trading is pure gambling. Only speculative and greedy people lose.
Small investors normally looses. The reason being that he don't have the knowledge, resources etc. However, want to earn money immediately. Share market becomes obsession in a day or later. As Pandava's lost Dropdi in Gambling, so the investor especially small investor looses his or her all near and dear ones b'coz of this market. Try to be sensible and not to be greedy.
