Two days, Nintendo has a big wave on Wall Street.

Two days in a row, Nintendo's shares have raised waves on Wall Street.

The game company's shares traded at $23.30 a day, up more than $5 trillion, or about 28%, compared with yesterday's closing price of 18.22 dollars. Yesterday, after Nintendo announced a move to develop a mobile game with Dena, a Japanese distributor, investors raced to buy the company's shares through the over-the-counter market, often called the pink single market. But today, as investment bank Jefferies Jefferies the company's ratings to "buy", the stock has continued to rise. That makes Nintendo's total market capitalisation at $20.65 billion trillion, and yesterday the company's total market capitalisation was about $16 billion trillion.

"In the end, Nintendo has taken a strategic transition and put its game series into the arms of smart devices." "We've been arguing about whether we need to adjust the company's rating," said Atul Goyal, an analyst at Jerry Attu Gauyere Group. Now, the company has launched a new business and has formed a capital alliance with Dena. We believe Mario, Zelda, Pokemon and King Kong, which landed smartphones and tablets, would greatly increase the company's profits. ”

Jefferies also sharply increased the standard prices of Nintendo, up from $12.70 trillion to $30.45.

Nintendo has long avoided letting its games land on other companies ' platforms. The company sees its own software as a way to sell its own hardware, but in recent years it has been struggling to make a profit. Investors are pleading with Nintendo to embrace the mobile platform, a request that has finally come true.

As part of a deal with Dena companies, the two companies will launch games that are only released on mobile platforms based on Nintendo's existing game series. No game series or characters are excluded, but Nintendo does not want to accept the business models common to mobile platforms. Nintendo also said it would not launch any of its existing games on smartphones or tablets.
