Stock trading involves buying and selling shares in companies in an effort to make money on daily changes in price. Traders watch the short-term price fluctuations of these stocks closely and then try to buy low and sell high.
This short-term approach is what sets stock traders apart from traditional stock market investors who tend to be in it for the long haul. While trading individual stocks can bring quick gains for those who time the market correctly, it also carries the danger of substantial losses. A single company's fortunes can rise more quickly than the market at large, but they can just as easily fall.
