Nintendo stock rises following 3DS announcement

You may have been a bit bewildered by Nintendo's out-of-nowhere announcement of a new DS a week before the North American launch of the DSi XL, but one group seems to have no issues with the timing or technology of the Nintendo 3DS: investors.

Marketwatch reports that Nintendo stock rose 9.7 percent yesterday in response to the hardware announcement. While it's hard to gauge exactly what it is about the 3DS that has inspired such confidence among investors, we would guess it's less about the current 3D trend and more about the fact that Nintendo announced a new thing, and Nintendo things have been good for stocks in the last five years or so.
