Bill Gates has returned to the top of Forbes magazine's annual list of the world's richest people, as rising stock markets swelled the ranks of billionaires, which included a record number of women. With a net worth of $76 billion, the Microsoft Corp co-founder reclaimed the top spot after a four-year hiatus, toppling Mexico's telecommunications mogul Carlos Slim Helu, who placed second at $72 billion, Forbes said in announcing the list on Monday. Amancio Ortega, the Spanish founder of clothing conglomerate Inditex SA, which includes the Zara fashion chain, ranked third at $64 billion.http://www.reuters.com/article/2014/03/03/us-forbes-billionaires-idUSBREA2222L20140303
