Shares have opened sharply higher in Asia after a rebound on Wall Street, while oil prices resumed their upward climb. South Korea's Kospi gained as much as 12% after its worst plunge ever the day before. In Tokyo, the Nikkei 225 surged 2.4%. U.S. stocks rebounded Wednesday as oil prices paused their ascent due to the war in the Middle East. Reports also gave encouraging updates on the American economy. The S&P 500 rose 0.8% and the Dow industrials added 0.5%. The Nasdaq composite climbed 1.3%. Uncertainty about the war has rattled financial markets this week, with most taking their cues from what the price of oil is doing.
