Stocks closed broadly higher on Wall Street for a second day as worries continued to ease over Britain's vote to leave the European Union, the AP reports. The gains over Tuesday and Wednesday erased more than half of the losses US markets suffered in the fallout from last week's vote. Banks, which had taken the brunt of the selling, rose more than the rest of the market Wednesday. Citigroup jumped 4%. European markets also posted solid gains and the pound edged up against the dollar following its plunge after the British vote last week. The Dow Jones industrial average rose 284 points, or 1.6%, to 17,694. The Standard & Poor's 500 index gained 34 points, or 1.7%, to 2,070. The Nasdaq composite climbed 87 points, or 1.9%, to 4,779.
