Nasdaq-100
The Nasdaq-100 holds the 100 largest non-financial companies listed on the Nasdaq. It is heavily concentrated in technology and megacap growth, which makes it more volatile than the S&P 500.
How the Nasdaq-100 is built
The 100 largest non-financial Nasdaq-listed companies by market cap, with rules that cap the very largest weights so no single name dominates entirely.

What to check before using the Nasdaq-100 as a benchmark
- Financial companies are excluded, so it is not a broad all-sector market benchmark.
- Technology and other growth-oriented businesses have an outsized role in the index’s makeup.
- Modified market-cap weighting can cap the largest positions, but concentration can still matter.

How to invest in the Nasdaq-100
You can’t buy an index directly — you buy a fund that tracks it. The most common way to follow the Nasdaq-100 is the QQQ ETF. Because it’s market-cap weighted, remember the largest holdings drive most of the moves — if you already own those names, you may be more concentrated than the broad label suggests.
