With the Nasdaq Composite Index hitting the magical 5,000 level for the first time in 15 years, it's important to remember how much has changed since then. Other than the optical 5,000 number, these two levels have very little in common with each other.
First off, most of the biggest components are not even the same. Of the top 10 weighted stocks in 2000, only three of them still remain in that group. Apple is in a league of its own, while Microsoft has steadily remained the second-heaviest company in the group. Intel and Cisco, darlings of the 1990s, are still in the top 10, but nowhere near as important as they used to be. Google, Amazon and Facebook were not the household names they are today.
