The Vienna Stock Exchange today reviewed the Austrian indices and announces the change of a free float factor as well as the new composition of the benchmark ATX Top Dividend. The free float factor of Addiko Bank AG decreases from 0.7 to 0.6 after shifts in the ownership structure. The ATX Top Dividend index gathers the 15 prime market stocks with the highest dividend yield. According to the "Rules for the Austrian Indices of the Vienna Stock Exchange" the index members of the ATX Top Dividend will change as follows:
| Inclusion | Exclusion |
|---|---|
| ANDRITZ AG | ADDIKO BANK AG |
| LENZING AG | CA IMMOBILIEN ANLAGEN AG |
| UNIQA INSURANCE GROUP AG | IMMOFINANZ AG |
| VOESTALPINE AG | POLYTEC HOLDING AG |
| ZUMTOBEL GROUP AG | RAIFFEISEN BANK INTERNAT. AG |
The changes will become effective on 19 December 2022. The next scheduled review of the composition of the Austrian national index ATX will take place in March 2023.
The calculation of Wiener Börse AG's indices is based on a quantitative procedure. According to "The Rules for the Austrian Indices of the Vienna Stock Exchange", the inclusion or exclusion of stocks from the ATX is reviewed twice a year (March and September). Decisions on new additions to the index are based on average daily trading volumes and the free float capitalization of companies. The Vienna Stock Exchange reviews the calculation parameters (number of shares, free float factors, representation factors) of the index on a quarterly basis. Once a month, the ATX watchlist is published. In the Index Committee, which met today and decides on the rules and regulations for the indices, representatives of institutional investors, trading members of the Vienna Stock Exchange, financial institutions that issue financial products on the indices, academic advisors and the Vienna Stock Exchange contribute their experience. A list of the Committee members is available.
