What is a good percentage point to sell a stock if it goes down right after purchases when daytrading?

Answer 1

it all depends on if you want to lose a little money or a lot. buy low, sell high is my motto. why would you buy a stock that does not have a position for growth? if the fundementals are right, down dips are an indication to buy more, not sell. you should keep stock that will grow, even a "day trader" needs a portfolio that he puts his future winners into.
