Deutsche Börse’s shares fell more than 6 per cent on Wednesday as investors and analysts showed disappointment with rising costs and poor trading revenues for Europe’s biggest stock exchange group.

Net income for the second quarter fell 34 per cent to €164.9m as Deutsche Börse struggled with what it said was market participants’ “reluctance to trade”. The group has confronted months of falling trading in equities and derivative, which it blames on the financial crisis. Electronic order book turnover for equities was down 44 per cent in the quarter compared with the same period last year.
