The Swiss franc followed the euro higher against the dollar on Wednesday, pulling away from a near two-week low against the greenback, as investors covered short positions following a euro sell-off linked to fresh Greek worries in the previous session. The franc rose 0.5 percent against the dollar to trade at 0.8829 compared to the New York close. It was down 0.2 percent against the euro, trading at 1.2171 per euro.
