Today’s review of the index composition results in the following changes according to the index rules: The catering company DO & CO Aktiengesellschaft will replace the construction company PORR AG in the Austrian leading index ATX. DO & CO qualifies for inclusion in the index due to the higher order book turnover and the free float capitalization in the current period. The new index composition of the ATX will take effect as of Monday, 24 September 2018.
According to “The Rules for the Austrian Indices of the Vienna Stock Exchange”, the inclusion or exclusion of stocks from the Austrian indices 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. Representatives of institutional investors, financial institutions that issue financial products on the indices, trading members of the Vienna Stock Exchange, academics advisors and the Vienna Stock Exchange contribute their know-how to the index committee, which approves the index rules. A list of the committee members is available online.
