Tokyo, June 12 (Jiji Press)--Japan's benchmark Nikkei 225 stock average temporarily surged over 2,800 points Friday morning, reflecting rising anticipation that the ongoing armed conflict between the United States and Iran would end. After rising as high as 67,065.94 in the early morning, the index of 225 major issues listed on the Tokyo Stock Exchange's top-tier Prime section finished the morning at 66,442.95, up 2,225.68 points, or 3.46 pct, from Thursday's closing. Risk appetite grew among Tokyo market participants, following climbs in major U.S. stock indexes on Thursday and a drop in crude oil futures. Investor sentiment brightened after U.S. President Donald Trump said on social media Thursday that he canceled planned strikes and bombings against Iran after Iranian leaders gave their approval in ongoing talks to end their conflict. On the TSE, artificial intelligence-linked names and semiconductor and electronic parts makers drew heavy buying. Memory maker Kioxia Holdings jumped more than 8 pct to finish the morning with market capitalization of 44.59 trillion yen, exceeding Toyota Motor's 43.77 trillion yen to become the biggest stock listed on the TSE.
