After word that Nintendo had topped sales of the original Wii with the newer Wii U after 41 days and a strong performance from the Nintendo 3DS, reports have indicated that Nintendo's stock has climbed 5.6 percent to 9,070 Yen, according to a Bloomberg.
The increase is the biggest gain since September 18th 2012.
There were concerns after the Wii U had failed to match its predecessor's figures after the first month on sale, but thanks to a push during the holiday season and a greater demand for the higher-priced Premium bundle, Nintendo pulled through.
