## What Is the DAX Stock Index?

The DAX stock index is a stock index that represents 40 of the largest and most liquid German companies that trade on the [Frankfurt Stock Exchange](https://www.investopedia.com/terms/f/frankfurt-stock-exchange-fra-.f.asp). The DAX uses a [free-float methodology](https://www.investopedia.com/terms/f/freefloatmethodology.asp) to calculate its weightings. It was created in 1988 with a starting index level of 1,163 points. DAX member companies represent roughly 80% of the aggregate [market capitalization](https://www.investopedia.com/terms/m/marketcapitalization.asp) that trades on the Frankfurt Exchange. The index was historically comprised of 30 companies but was expanded to 40 in 2021.

## Understanding the DAX Stock Index

The DAX index tracks 40 large and [actively traded](https://www.investopedia.com/articles/active-trading/021115/how-find-most-actively-traded-stocks.asp) German companies. It is considered by many analysts to be a gauge of Germany's economic health. The companies listed in the DAX are multinational corporations that influence both Germany's economy and the global economy at large. The success of these companies has greatly contributed to what is known as the "[German economic miracle](https://www.investopedia.com/articles/economics/09/german-economic-miracle.asp)" or _Wirtschaftswunder_, a term that describes Germany's rebirth after World War II.

The companies in the DAX index span a wide range of industries. For example:

*   Adidas AG develops, manufactures, and markets popular athletic footwear, apparel, and equipment.
*   Allianz SE is a global financial services company that focuses on providing customers with insurance and asset management products
*   Bayer AG is a pharmaceutical and consumer health company founded in 1863 and is well-known for its pain and allergy-relief products

## Special Considerations

Unlike most indices, the DAX is updated with [futures](https://www.investopedia.com/terms/f/futures.asp) prices for the next day, even after the main stock exchange has closed. Changes are made on regular review dates, but index members can be removed at any time if they no longer rank in the top 45 largest companies or added if they break the top 25.

The vast majority of shares on the Frankfurt Exchange now trade on the all-electronic [Xetra](https://www.investopedia.com/terms/x/xetra.asp) system, with a high adoption rate for the stocks of the 40 DAX members.

> **Important**
>
> As a blue-chip stock market index, the DAX is very similar to the Dow Jones Industrial Average (DJIA), which also tracks large, publicly owned companies.
