Smart Mobs namechecked us earlier in the week, so we are returning the favor. It appears that the big dive in Tokyo stocks last week due to allegations against Japanese Internet company Livedoor were fed by mobile traders reacting to market news.

According Business Week, who ran the original story, Japanese traders equipped with clamshell phones (don't know why the design makes a difference) traded over ¥1 trillion in volume for the first time back in November of last year. The trend is so strong that Matsui Securities expects up to 20% of its traders in the next year to be connecting by mobile alone, not using other online or physical trading channels.

chalk up another one for the ability of mobiles to provide on-the-spot reaction from users. Imagine if most of those traders last week had been out in a car or somewhere else without access to a single push-button trade what the volumes may have been?
