In the days following the launch of "Pokemon Go," shares of the company behind the incredibly popular mobile game were on a tear.
Yet just as Nintendo stock hit highs not seen in six years, so did interest in the stock's short positions, or investors making bets that the price will fall. The stock dropped slightly from its high this week but is still way up from two weeks ago.
While the stock price has more than doubled this month, short interest in the gaming company's shares has tripled in the last 10 days. That suggests that "Pokemania" has attracted plenty of doubters when it comes to the mobile game sustaining Nintendo's current stock level.
In fact, since the launch of the game, Nintendo's U.S.-traded ADR more than doubled in market value, soaring as high as $18 billion just in a span of two weeks.
