The Deutscher Aktienindex 100, also known as DAX-100, is a former price-weighted index that represented top-traded 100 blue-chip or heavily traded stocks on the Frankfurt stock exchange.
A Little More on What is the DAX
The DAX-100 included 30 DAX equities and 70 MDAX equities listed on the Frankfurt Stock Exchange. However, since March 24, 2003, the MDAX reduced the number of equities from 70 to 50 and the former DAX-100 was substituted by the HDAX.
DAX-100 included companies like Siemens, Lufthansa, Adidas, Bayer, Porsche, and others.
The DAX (Deutscher Aktien Index) – The DAX or DAX 30 takes the prices from the Xetra trading venue. Xetra is operated by the Deutsche Borse. DAX 30 measures the performance of the 30 largest and most actively traded German companies. The performance is measured by the volume of the order book and market economy. DAX30 may not reflect the vitality of the whole economy as it deals with a small selection.
The MDAX – MDAX is also calculated by Deutsche Borse. It contains 50 Prime standard shares which are not there on DAX 30 and are from traditional sectors but not technology. Prime Standard is a section of the Regulated market with a higher level of transparency.
The TecDAX – TecDAX tracks 30 top traded technology companies on Frankfurt stock exchange that are not already there on DAX.
The HDAX – HDAX is the reformed version of DAX-100. It includes DAX, MDAX, and TecDAX. It reflects the price development of all shares present in these three sections. It is a broader index covering all sectors registered in the EU regulated markets Prime Standard segment.

This article investigates the impact of the introduction of the euro on the interactions across the New York, London, Frankfurt and Paris stock markets. After controlling for possible returns and volatility spillovers, the article focuses on the correlations of shocks using the framework of Dynamic Conditional Correlations (DCC).

The intraday ex ante profitability of DAX-Futures arbitrage for institutional investors in Germany-The case of early and late transactions, Röder, K., & Bamberg, G. (1994). Finanzmarkt und Portfolio-Management, 8(1), 50-62. The German futures market “Deutsche Terminbörse” started trading in DAX futures contracts on November 23, 1990. The foundation of these futures contracts, the DAX1, is based on the prices of 30 German Blue Chips. The standardised delivery months are March, June, September, December. The German Options and Futures Exchange simultaneously lists three subsequent delivery dates. The final cash settlement takes place on the third Friday of the delivery month.
Life time of correlation between stocks prices on established and emerging markets, Buda, A. (2011). This paper suggests that the correlation coefficient between stocks depends on price history and includes information on hierarchical structure in financial markets. The paper introduces the Life Time of Correlation between stocks prices to know how far to investigate the price history to obtain the optimal durability of correlation. The research is carried out on emerging (Poland) and established markets (in the USA, Great Britain and Germany). Other methods, including the Minimum Spanning Trees, tree half-life, decomposition of correlations and the Epps effect are also discussed.
Intraday volatility spillovers in the German equity index derivatives markets, Booth, G. G., & So, R. W. (2003). Applied Financial Economics, 13(7), 487-494. This paper examines the intraday information transmission process among the Deutscher Aktienindex (DAX), DAX futures and DAX options in Germany. Using the extreme value volatility approach developed by Booth et al. , the volatilities of the three markets are found to spill over to one another. These results support the notion that the three index assets are informationally linked, and the three markets should be considered a complete system for intraday information processing.
DAX’s January 2008 Crash: A Routine Correction or Outright Panic, Balaz, M. (2009). This work provides a comprehensive study of the January 2008 stock market downturn and its impact on DAX index. It finds three possible causes of the crash: adverse economic news, technical trading signals and possible market manipulation (by SocGen). The piece also finds strong interdependencies among world equity indices during this period. It further examines DAX’s development in the preceding years and do not find any proof of a price bubble.
Short-and long-term links among European and US stock markets, Gerrits, R. J., & Yuce, A. (1999). Applied Financial Economics, 9(1), 1-9. The relationship between equity markets in various countries has been examined extensively in the literature. This study tests the interdependence between stock prices in Germany, the UK, the Netherlands and the US, using daily closing prices for the period between March 1990 and October 1994. Results of the tests show that the US exerts a significant impact on European markets. Implications of the findings are documented.
How wacky is the DAX? The changing structure of German stock market volatility, Werner, T., & Stapf, J. (2003). Discussion paper Series 1/Volkswirtschaftliches Forschungszentrum der Deutschen Bundesbank. This paper investigates the volatility structure of the German stock market index DAX and its constituents. Using a recently developed test, the paper finds a volatility break in 1997.The paper suggests that domestic factors which may help to explain the break in volatility are the growing number of institutional investors and the increase in the volatility of longer-term interest rates.
Deep Learning with Gated Recurrent Unit Networks for Financial Sequence Predictions, Shen, G., Tan, Q., Zhang, H., Zeng, P., & Xu, J. (2018). Procedia computer science, 131, 895-903. This paper suggests that gated recurrent unit (GRU) networks perform well in sequence learning tasks and overcome the problems of vanishing and explosion of gradients in traditional recurrent neural networks (RNNs) when learning long-term dependencies. It also analyses their seldom use in financial time series. The paper proposes GRU networks and its improved version for predicting trading signals for stock indexes of the Hang Seng Indexes (HSI), the Deutscher Aktienindex (DAX) and the S&P 500 Index from 1991 to 2017, and compare the GRU-based models with the traditional deep net and the benchmark classifier support vector machine (SVM).
