Spanish global clothing giant Inditex, owner of the Zara brand, posted Thursday a 20-percent surge in nine-month net profits thanks to higher sales as the economy in its home market Spain improves.The group said in a statement that net profit rose to 2.0 billion euros ($2.2 billion) between February and October.The results are in line with expectations from analysts polled by Factset who forecast the company would post profits of 2.01 billion euros.Expansion efforts had weighed down last year’s results, but profits rose this year by a greater margin than the healthy 16.6-percent rise in sales to 14.7 billion euros.
