Nintendo's stock prices in America have fallen to a two year low.

When the American stock market closed on Friday Nintendo's ADR stock sat at $30.10, the lowest figure for the company since 2009. Since the start of April the stock has fallen by 12%, seemingly over fear of 3DS stock levels and the continuing problems in Japan.

In spite of strong launch sales in all territories Nintendo's stock in Japan has also recently fallen. The console was also overtaken by the PSP in Japan last week, leading to comments that the prediction of worldwide shipments of 4 million units by the end of March will not be met according to GamesIndustry.

American charting company NPD are due to deliver their March charts on Thursday, which should hopefully give a clearer figure of how well the Nintendo 3DS has done in America. While no Nintendo factories were damaged in last month's earthquake and tsunami and Nintendo confirming stock levels will not be affected it appears that foreign investors are still cautious.
