Mystery Gamer Makes Millions Moving Markets In Japan

HughPickens.com writes Jason Clenfield writes in Businessweek that tax returns show that a former video game champion and pachinko gambler who goes by the name CIS traded 1.7 trillion yen ($15 Billion) worth of Japanese equities in 2013 — about half of 1 percent of the value of all the share transactions done by individuals on the Tokyo Stock Exchange. The 35-year-old day trader whose name means death in classical Japanese says he made 6 billion yen ($54 Million), after taxes, betting on Japanese stocks last year. The nickname is a holdover from his gaming days, when he used to crush foes in virtual wrestling rings and online fantasy worlds.

"Games taught me to think fast and stay calm." CIS says he barely got his degree in mechanical engineering, having devoted most of college to the fantasy role-playing game Ultima Online. Holed up in his bedroom, he spent days on end roaming the game's virtual universe, stockpiling weapons, treasure and food. He calls this an early exercise in building and protecting assets. Wicked keyboard skills were a must. He memorized more than 100 key-stroke shortcuts — control-A to guzzle a healing potion or shift-S to draw a sword, for example — and he could dance between them without taking his eyes off the screen. "Some people can do it, some can't," he says with a shrug. But the game taught a bigger lesson: when to cut and run. "I was a pretty confident player, but just like in the real world, the more opponents you have, the worse your chances are," he says. "You lose nothing by running." That's how he now plays the stock market. CIS says he bets wrong four out of 10 times. The trick is to sell the losers fast while letting the winners ride. "Self-control is so important. You have to conserve your assets. That's what insulates you from the downturns and gives you the ammunition to make money."

    No.. $15 billion volume not investment. He could have started with 1M and traded 15000 times.

    As Warren Buffet says, in the short run the stock market is a voting machine, in the long run a weighing machine.

    In the long term, the value of a stock is it's future free cash to shareholders, discounted by time and
    risk. Over time this has been proven to be true. P/E is backwards looking, so the fact that you can find a few companies without P/E ratio doesn't prove much. (but yes, it is easier to model and discount cash flows when you have a stable and positive P/E ratio.)

    Short run – yeah – the market runs off on supply and demand, and tends to go with what is popular.

    So who is selling when he is buying? Wouldn't he constantly be behind the curve? Paying too much for the stock and selling for too little?

    You are touching on one of the great debates. Momentum trading is one of those anomalies that should not work in theory but does in practice. Why? Ideas have been kicked around for the last 20 years. Here is a link to a possible explanation.
