Nintendo's shares lacking GO

You've got to catch them all ....

But Nintendo's announcement that Pokemon go won't net them big profits has seen their shares catch a cold.

The news sending stocks tumbling almost 18% Monday

The game's release triggered massive buying in Nintendo's shares, so as Reuters Markets correspondent Vikram Subhedar says they're still looking healthy.

Vikram Subhedar, Chief Correspondent, European Stock Markets, said: "Even with today's fall they're up about 60 percent since the day before Pokemon Go launched in the US."

Nintendo's announcement came on Friday, with a warning that the smash hit game would only have a limited impact on earnings.

Pokemon go was developed by a US affiliate, And Nintendo says income from licensing and fees will be limited.

But that might just be the short term outlook.

Independent market analyst, Darren Sinden, said: "I think as a test case it has done very well. Ten million downloads in a day in Japan, of course the hard part of all of these things is monetising them, I believe Nintendo have set a precedent and I hope they will be able to capitalise on that going forward."

Pikachu and co may have largely eluded Nintendo's balance sheet at the moment.

But with the Kyoto-based gaming company set to report first-quarter earnings on Wednesday, investors will be looking to see where they may pop up next.
