Euronext stock exchange operator took over all shares in Oslo Børs. That emerged Thursday from a statement from the company. Euronext already owned 99.4 percent of the shares and is now also acquiring the remainder through a “mandatory acquisition”. Euronext, which operates the stock exchanges in Amsterdam, Brussels and Paris, among other things, was involved in a bidding battle with the American company Nasdaq. The stock market operator also announced that the average daily transaction value on the Euronext stock exchanges fell by 14 percent in June compared to the same month a year earlier, to almost 7.6 billion euros. Compared to May, there was a 3.4 percent growth. Trading in index funds (ETFs) had an average daily transaction value of 227 million euros in March. That is 15.3 percent less than a year earlier and 10.7 percent less than a month ago. The average daily volume with index derivatives reached 228,099 contracts, with individual share derivatives 275,769 contracts.
