The Swiss Exchange has slashed the cost of trading for the second time this year just two weeks after it confirmed its trading activity dropped off heavily last month.

SWX and virt-x, its London-based electronic stock market, have cut the cost of trading on the two exchanges by 15%, a move the exchanges estimate will equate to annual savings of Sfr40m (€23.8m) for users. It is the second cut this year after the exchange group took 15% off the cost of trading on virt-x in January.
