The price of the Nasdaq 100 indicates whether the share prices of the companies on the index are rising or falling. If the price of the Nasdaq 100 is increasing, it means that a specific company or group of companies are experiencing gains, which is reflected in the price of the overall index. Conversely, if the Nasdaq 100 price is falling, it means that companies on the index are experiencing a decline in price.
The Nasdaq 100 ranking is based on a weighted average of share prices. This means companies with a larger weighting will often see their share price fluctuations have a correspondingly outsized impact on the wider index.
