Reuters - Inditex, the world's biggest fashion retailer, will accelerate investment in 2014 to open more new stores after results last year were hit by falling currencies outside the euro zone and the cost of revamping flagship stores. The owner of the Zara brand reported on Wednesday that core annual profit in the 12 months ending Jan. 31 was flat at 3.9 billion euros ($5.4 billion), the first time growth has stalled since it went public in 2001, but meeting analyst expectations.
