Deutsche Börse, the German exchange group, is likely to report a 19% increase in second quarter profits today, as higher revenues from the company's transatlantic derivatives business offset a slowdown in equities trading, according to analyst predictions.

The group, which reports its second quarter results after market close this evening, will say net profit rose to about €251m ($390m) in the three months to the end of June, from €211m a year earlier, according to the mean forecast of eight analysts surveyed by Bloomberg.
