According to NASDAQ.com, "The NASDAQ Composite Index measures all NASDAQ domestic and international based common type stocks listed on The NASDAQ Stock Market. The NASDAQ Composite includes over 3,000 companies, more than most other stock market indexes. Because it is so broad-based, the Composite is one of the most widely followed and quoted major market indexes."
WHAT DR. ED SAYS:
The NASDAQ serves as a key indicator of the overall economy and market. This particularly broad-based index represents many of the technological-based companies, differing from the more diverse DJIA. Fluctuations in the NASDAQ tend to be slightly more volatile than in its counterpart, the DJIA. This index can be used to monitor the overall appetite for growth in the economy, but is heavily tied to technology.
