The Dow Jones and S&P 500 are NOT the same things as the entire market. The S&P 500 are the largest 500 companies listed, and the Dow is an index of 30 huge, established companies. Both of these indicies err towards stability, not growth. If you wanted to invest in a company with growth potential, would put your money into a new business with lots of potential, or a huge business which has already reached that potential?
