It was welcome news for Koreans, among the leading investors in Britain during the past decade. Sure, the growth number was a long way from the 9.2% posted in the same quarter last year, when Seoul was rebounding from the financial crisis. But that was off a low base, from when the Korean economy took a huge tumble after the 1997-98 financial-crisis. Massive corporate conglomerates, or chaebols, have since been struggling for survival and Korea's stop-start efforts to reform the economy have put it in the caveat emptor basket for investors. Not any more. Korean stocks are up 15% so far this year to be one of Asia's best equity performers.
