The NASDAQ Exchange is one of the largest electronic exchanges in the world and has gone far beyond the US market. Many indexes have been introduced over the last couple of years on this exchange. These indexes cover not just the NASDAQ market and the US economy, but characterize different markets all over the globe. The NASDAQ 100 and NASDAQ Composite indexes are the most popular indexes and most recognized from this group by traders. The NASDAQ Biotechnology index and other older indexes are also popular. The financial crisis in 2008 has caused the NASDAQ 100 Financial, NASDAQ Bank and NASDAQ Other Financial indexes widely to be analyzed as well.
The NASDAQ Composite index comprises the public companies traded on the NASDAQ Exchange and is used by analysts in conjunction with the NYSE Composite and Amex Composite indexes to get a complete picture of the US economy.
The NASDAQ 100 index is the most popular index. It includes the largest non--financial domestic and international publicly-traded companies on the NASDAQ Stock Exchange. In contrast, the NASDAQ 100 Financial index covers the 100 largest financial companies and was launched at the same time as the NASDAQ 100 index.
The NASDAQ Biotechnology index is based on the largest companies in the pharmaceutical and biotechnology industries.
With many NASDAQ indexes, you may find the pair of Equal Weighted index which is comprised of the same stocks that the main index is. The only difference between them is the method used to calculate the index value.
Among the NASDAQ indexes, you can find indexes that cover the following US market sectors: Telecommunications, Biotechnology, Industrial, Insurance, Health Care, Technology, Ex-Technology, Computer, Financial, Banks, Neurotech, and Internet. In addition, there are many indexes that cover foreign markets. Such indexes as NASDAQ China Index, NASDAQ-Canada Index and NASDAQ Israel Index cover non-US markets.
At the same time, you can find indexes that cover domestic and international companies that are traded not only in the US market, but all over the world. As an example, the NASDAQ OMX 100 index is comprised of companies that are traded on both the US market and European markets.
As you can see, the wide range of indexes allows NASDAQ to cover sentiment in each market sector, by delivering to consumer the complete picture of not only the US economy, but also the economy of Canada, China, and Israel, as well as monitoring the health of the European economy.
At present, more and more public companies are moving from the trading floor into computerized (over the counter) trading and the importance of the NASDAQ indexes is growing. Even if you are not involved in index trading, before beginning trading, it is highly recommended that you consider a brief analysis of the market sector to which the selected stocks belong. With the variety of index products on the NASDAQ, this should not be a problem.
