The man who turned the Japanese stock exchange upside down

On February 4, the Tokyo stock exchange opened for 6 minutes, but dozens of major stocks still had no transactions.

Suddenly, an order appeared on the market to buy 300,000 SoftBank shares with a total value of more than 2 billion yen (nearly 20 million USD).

The person who turned things around for SoftBank was still wearing pajamas, sitting in a room full of comic books.

CIS is describing how he tracks the stock market.

Expecting this code to increase again is very risky.

90 minutes later, this former video game champion and pachinko gambler with the nickname CIS made a profit of 140.6 million yen.

After a decade of playing stocks, starting from a novice, CIS said he has built a fortune of over 16 billion yen.

Only a few people knew his real name, and no one had ever seen him work.

CIS means death in Japanese.

CIS does not want to reveal its identity for fear of becoming a target for criminals.

Last year was a very prosperous year for Japanese investors.

CIS’s first big hit was in December 2005, thanks to a typing error by an employee of Mizuho Securities Company.

CIS is also famous for its bold statements on 2channel – Japan’s largest forum.

In 2011, CIS appeared on TV, in the show It’s OK to Laugh.

The bankers probably don’t know who is being interviewed on TV.

In high school, CIS often skipped class to play pachinko – a popular slot machine in Japan.

While in college, CIS spent most of her time playing the role-playing game Ultima Online.

Superior keyboard skills are a must if you want to win.

This is also the strategy he applies in the stock market.

CIS started playing stocks when he was in his 20s and working for a small company.

Instead, he just listens to news from forums and attentively monitors electronic boards on the stock exchange to predict market trends.

According to Hersh Shefrin, Professor of Behavioral Finance at Santa Clara University, the human mind tends to bet on the opposite.

2 years after learning this principle, CIS was earning 80 million yen per day just during his time at the company.

Since then, he has made millions of transactions, CIS said.

The majority of CIS assets are stocks and cash.

Murakami believes that CIS’s success comes from its ability to detect flaws in the trading algorithms used by banks.

This year, as the effects of Mr. Abe’s policies are gradually fading, and the Nikkei index fell 5% in the first eight months, many investors who made good profits last year are gradually withdrawing from the market.

But CIS doesn’t think so, even though by the end of the summer, he barely earned any money.
