TOKYO, Oct. 27 (Xinhua) -- Japan's key Nikkei stock index closed above the 50,000-point line for the first time on Monday, ending at a new all-time high, amid eased concerns over world trade tensions and hopes for new Japanese Prime Minister Sanae Takaichi's policies.

The benchmark Nikkei stock index, the 225-issue Nikkei Stock Average, ended up 1,212.67 points, or 2.46 percent, from Friday to close at 50,512.32.

The broader Topix index, meanwhile, finished 55.60 points, or 1.70 percent, higher at 3,325.05, also hitting a new record high.

On the stock market, sentiment was lifted by receding fears of escalating world trade tensions. High approval ratings for Takaichi's government was also a positive factor, which boosted investor confidence about political stability and fueled expectations for aggressive fiscal policy, analysts said. ■
