TOKYO -- For investors that pick Japanese stocks based on their own analysis of fundamentals, the choppiness seen during earnings season this year has been wrenching.
On a day when the Nikkei Stock Average advanced 1.6% on the latest news in the U.S. presidential race, Internet Initiative Japan dropped 11%. Monday's decline was the biggest in more than two and a half years for the internet service provider, which last week cut its full-year net profit forecast by 40%.
