Stock market today: World shares slide after Wall St rout driven by high yields, mixed earnings

Shares have skidded in Europe and Asia after Wall Street tumbled as bond yields tightened their chokehold. Sentiment also dimmed after some of the most influential companies turned in mixed profit reports. Tokyo's Nikkei 225 and the Kospi in Seoul were more than 2% lower. U.S. futures slipped and oil prices also fell. On Wednesday, the S&P 500 tumbled 1.4%, falling back to where it was in May. Some of the heaviest losses hit Big Tech stocks, which dragged the Nasdaq composite to its second-worst drop of the year, at 2.4%. The Dow Jones Industrial Average fell 105 points. The yield on the 10-year Treasury jumped.
