Index Investing
The Nasdaq Composite Index
The Nasdaq Composite Index represents all the stocks that trade on the Nasdaq stock
market. The recent surge in popularity of technological stocks has launched the
Nasdaq into the spotlight. Consequently, the composite index has become one of the
premier indexes in the world.
Don't confuse the Nasdaq composite with the Nasdaq 100, which is comprised of the
100 largest non-financial companies on the Nasdaq stock market.

Advantages: The Nasdaq Composite is heavily weighted in technology and Internet
stocks. As such, the companies listed in the Composite are considered to have high
growth potential.
Disadvantages: Companies on the Nasdaq tend to be more speculative and risky
than those listed on the NYSE. Because of this, the Nasdaq composite index is much
more volatile than other broad indexes. The advantage of being mostly tech can also
be a disadvantage. That is, when tech suffers, so does this index.
Investing: As far as we know, there aren't any index funds that track the
Nasdaq composite. A good substitute is the Nasdaq 100, which is extremely easy to
buy either through an index fund or the QQQ (the Exchange-Traded Fund (ETF) that
tracks the Nasdaq 100).
