Tokyo stocks have surged over the past 2½ months, propelled to their highest in 33 months by monetary and fiscal stimulus measures being advocated by Prime Minister Shinzo Abe and receding jitters over the global economy.

While many market analysts predict the Tokyo market has more room to rise, some express caution against too much optimism because of risks from both domestic and international events in the coming months.

Since mid-November, the benchmark 225-issue Nikkei index has surged about 29 percent to over 11,100 points, attracting money from both foreign and individual investors, with daily trading value doubling to about ¥2 trillion from levels earlier in the year on the first section of the Tokyo Stock Exchange.
