Japan Stunned After Biggest Ever, $617 Billion “Fat Finger” Trading Error Slams Stocks

A few days ago, Bloomberg had a fascinating profile of the person, pardon degenerate Pachinko gambler, who goes under the name CIS, and who is the “mystery man who moves the Japanese market.” In a nutshell, CIS, a momentum day trader and living proof of survivorship bias in finance (because for every CIS who has, allegedly, made it some 999,999 have failed) has amassed a fortune that he says now exceeds 16 billion yen after having traded 1.7 trillion yen in his career, generating an after tax profit of 6 billion yen in 2013 alone. Of course, the numbers are likely wildly fabricated for pageview purposes becuase as Bloomberg itself admits, “CIS didn’t offer a complete accounting of his investing returns and his wealth for this story, and some of his claims can’t be verified.”

That said, it is indeed the case that Japan has increasingly become a cartoon market in which while days can go by without a single trade taking place in its rigged bond market, where the BOJ has soaked up all the liquidity, when it comes to equities, it has become a free for all for “Mr. Watanabes” who have never taken finance, accounting or economics, but who know all about heatmaps and chasing momentum, and as a result, in a rising market/tide environment, have all grown ridiculously rich.

The problem, of course, is that what some may call a market is anything but, and has become a fragile playground for a few technicians who move massive sums of money from Point A to Point B, hoping to outsmart the few remaining others, while in the process earning the rents that the BOJ is eagerly handing out by injecting liquidity at a pace that dwarfs what the Fed did for the past 2 years. The other problem is that it is a merely of time before everything crashes into a pile of smoldering rubble thanks to the unprecedented fragility that is now embedded in every market, although most likely in Japan first.

Which leads us to what just happened in Japan when as Bloomberg reports, stock orders amounting to a whopping $617 billion (yes Billion with a B) or more than the size of Sweden’s economy, were canceled in Japan earlier today, for reasons unknown although the early culprit is that this was one of the biggest trading errors of all time.
