“
he Dow Jones Industrial Average is the sum of the largest 30 corporations, although they represent the bulk of the trading on that exchange. This average dominates everybody’s thinking about the market being up or down or whatever. Try to make individual stock picks and forget about the market. A good market could pull your stock up and, a bad one could pull it down, but the real investment factor is how well the company is managed and performs within the stock market.
