How to win in the stock market

At first you have to buy the bottom level of the stock price, and also you need to sell the higher level of it. I like to have the short position, because I can get benefit when the situation is bad.
I believe that no matter higher the stock price rise, it must come back to the former level. But
if you have the long position, you might have lost big money. Whenever the stock price you have goes down, you must do the Loss Cut. This is the most important thing about enjoying the stock world.
