In Europe, the Stoxx 600 index, the broadest measure of regional share prices, was marked 0.23% higher in the opening 90 minutes of trading as the DAX performance index in Germany gained 0.44% to scale back over the 13,000 mark and France's CAC-0 added 0.4% as investors took advantage of modestly weaker euro, which slipped below the 1.18 mark against a resurgent greenback.
