Surging Single Currency Caps Regional Gains

European stocks opened higher Wednesday, with U.S. equity futures pointing the Dow Jones Industrial Average over the 22,000 market at the start of trading, after a robust set of quarterly earnings for tech giant Apple Inc. (AAPL) - Get Report  boosted sector sentiment and helped lift markets across Asia.

Britain's FTSE 100 gained at the start of trading, with similar percentage gains around the region. However, the surging European single currency, which was marked 0.16% higher at 1.1816 against the U.S. dollar at the start of trading, capped gains around Europe.
