Rare Day of Red Amid Global Gains

European stocks opened lower again Friday as investors continue to eye developments in global crude markets and prepare for a series of key activity data releases from the currency area.

Britain's FTSE 100 is poised to slip around 17 points, or 0.24%, at the opening bell, according to financial bookmakers IG, with gains being held down by both a firmer pound and softer oil and energy stocks.

The slip will likely erase all of the benchmark's U.S. dollar adjusted gains for the past year, on the anniversary of Britain's decision to leave the European Union, putting it firmly behind Germany's DAX performance index, which has risen 22.3% and Spain's IBEX 35, which has gained 18% in U.S. dollar terms.
