NEW YORK (Reuters) -Global stock markets extended their recent rout on Friday, with S&P 500 companies wiping out $5 trillion in stock market value since U.S. President Donald Trump unveiled sweeping tariffs on Wednesday, while investors fled to the safety of government bonds. The Nasdaq confirmed it was in a bear market, ending more than 20% below its record high close, while oil prices and other commodities plunged. That $5-trillion loss marked a record two-day decline for the S&P 500 benchmark, exceeding a two-day loss of $3.3 trillion in March 2020 when the pandemic ripped across global markets, according to LSEG data compiled by Reuters.
