TOKYO -- As the link between the yen and Japanese share prices seems to grow ever tighter, market watchers see a connection to attempts by foreign investors to beat currency risk.
The Nikkei Stock Average advanced nearly 600 points, or 3.68%, on Tuesday as it lurched back into forward gear following the previous day's reversal. The Japanese currency zigzagged in a range of nearly 1 yen against the dollar on a volatile day in Tokyo markets.
