A day trader watches stock prices carefully. When he sees a stock rise in price, he uses the computer to buy shares of the stock. If the stock continues to rise in price in the next few minutes, the day trader sells the shares quickly to make a small profit. Then he looks for another stock to buy. If a stock goes down instead of up, he sells it and accepts the loss. _______________________This VOA Special English program, Words and Their Stories, was written by Frank Beardsley.
