TOKYO -- Many Japanese stocks made wild price swings after the companies released April-December earnings this season. But calls to curb the short-term trading blamed for these fluctuating shares could damage market liquidity.
Electronic equipment maker Ulvac surged 17% Tuesday after upgrading its full-year forecast following Monday's close. Minebea Mitsumi, which also lifted its fiscal 2016 projection, soared 19% at one point. By contrast, Nikon plunged 15% after saying it expects to sink deeper into red ink.
