I'd say to hold on Nintendo until shortly before one of their big announcements.
When did they say that they would begin breaking even on 3DS?
And when is their next quarterly?
And when is e3 this year?
Might want to wait a month or two on this.
Then you get to see how the exchange rate is faring, and hopefully, e3's wiiU will explode, 3ds 2d mario will explode, presidential elections here always make stocks go up, etc. This could be a good year to make some money on Ninty stock, but specifically right now might not be a good choice.
But, I'd keep a close eye on them everyday for the next couple months. You want to buy it as low as possible, and if it starts going up suddenly, I'd say to jump in.

Apple is at $454.23 right now, even if the stock gains $20 that's only a 4.4% gain.

Nintendo is at $17.01 right now, a $20 gain would represent a 115% gain, even a $5 gain would represent a 29% gain. So for the same amount of money invested, the Nintendo stock is the one with the greater potential for gain right now.

Uh.... sort of. Any loss at this point which be a greater loss, yes... but you have to keep in mind the perspective of time, here. It's a long-term sort of thing. The likelihood of Nintendo's stock failing to rise above $17 over the course of the next few years is remote, if one has any confidence in their software success (which many do, and reasonably so).

That's why it's a "super mega buy". The idea that it would stay this low, full-stop, for years on end? Not very likely

Those aren't displaying for me, would you mind explaining what you're illustrating?

The price of a stock in all reality has absolutely nothing to do with whether a stock can grow more or not.  Apple has simply chosen not to do all sorts of splits throughout the days to keep their stock price down (which I still don't get the point of).  Nothing restricts Apples stock from going to 600 anymore than something limits Nintendo from going up to 20.

Warren Buffets stock, last I checked, actually has a price of like 19,000 or 20,000.

That's a very good chart, but it illustrates exactly why they feel now is the time to buy Nintendo stock. If you think it might go up at all in the next few years, you stand to make serious gains!

Stock splitting is actually super neat in that it lets more and smaller investors (like me) jump onto the good ship Investment. I couldn't buy a reasonable amount of Apple stock even if I wanted to.

It would be very, very, very surprising if Apple stock increased to over $1200 a share in the same timeframe that Nintendo's stock could double in value.

For smaller investors, but if somebody is going to invest, say $5000 in a stock, it generally isn't going to be a big difference whether the stock is $200 or $20.  I'm not particular knowledgeable on the subject, but it MIGHT even be possible in some instances to purchase fractions of a stock.

Yes, I would be baffled for something like this to happen.  But I would also be much less surprised to see Nintendo stock go down to 8 versus Apple decreasing to 200.

While one may be able to make more investing in Nintendo, one has to determine whether the increased risk is worth it or not.  The plain and simple truth is that Apple is a much less risky investment than Nintendo.
