Eurex, the derivatives exchange 50% owned by Deutsche Börse, posted a sevenfold increase in earnings before interest and tax (Ebit) in the first nine months of this year, rubbing salt in the wounds of the London Stock Exchange (LSE).

Ebit from Eurex grew in the first nine months of the year to €84m ($75m), while Ebit from the Börse's Xetra segment, or cash market, halved to €30m.
