TOKYO -- As Nintendo continues to soar on the runaway success of "Pokemon Go," some market watchers are sounding the alarm over the stock's equally runaway valuation.
"I trade 5 billion yen to 7 billion yen [$47.1 million to $65.9 million] in daily value, and I earned a total profit of about 50 million yen," a retail investor here said of Nintendo. Turnover of the video game company accounted for about 30% of Friday's total on the first section of the Tokyo Stock Exchange. The stock price has roughly doubled since July 8.
