Nintendo's Stock Soars Toward Best-ever Gain In The U.S.

The U.S.-listed shares of Nintendo Co. Ltd. soared 35% to a five-year high in very active trade Monday, as fervor over the Japanese gaming company's "Pokemon Go" app launched last week continues to grow. That would be the biggest one-day percentage gain since the shares started trading in the U.S. in June 1989, and would put them on course to close at the highest level since June 7, 2011. Volume in the stock, which trades on the OTC Pink marketplace, reached 2.7 million shares as of 11:30 a.m. ET, was nearly 27 times the full-day average, according to FactSet. The stock has run up 57% year to date, while Japan's benchmark Nikkei 225 Index has tumbled 17% and the S&P 500 index has gained 4.7%.
