Following a poll of ATX Index Committee members, Wiener Börse announces a free float factor adjustment for BUWOG AG from 1 to 0.3, taking effect as of 19 March 2018. After yesterday’s publication of Vonovia SE’s successful takeover bid the free float decreases significantly, prompting for a timely adjustment in the leading index ATX.
On Monday, 19 March 2018, also the new composition of the ATX will take effect – as announced on 6 March 2018. FACC AG and AT&S Austria Technologie & Systemtechnik AG will replace AGRANA BETEILIGUNGS-AG and Zumtobel Group AG.
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 Watch List” 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.
