A trader trades in shares every day, or at least every week or month. They buy low and sell high as quickly as possible; they don’t care about the company or the fundamentals behind it all that want is to earn more money by benefiting the trend of the share. Whereas an Investor has a long-term investment horizon and invests for the long-term. They are not looking for short-term gains, instead they want to buy stocks that have potential for growth over an extended period of time.
