TO: Ishkabibble,
Well, people generally are willing to pay a premium on top of market value for something that is good. This is true regardless it is short term, mid-term and long term. This is true regardless it is stock or not. It can be a cars, coffee, houses, computers, ipod, and wiis. Why is that? I am not sure. Maybe pride, self-identity, or culture related. I don't know. I believe this Psychological element has something to do with the stock market's behavior. AND, it is not factored into stock analysts appraisal value calculation.
My point is this premium is keep increasing and therefore, when I sell Nintendo later on, I will get a margin plus whatever the increasing in the value of the company.
Sure, the standard investing guideline still applies...for long term, and diversify your portfolio.
You can tell because people are just willing to buying Nintendo at very expensive prices. Back in the summer when I bought NTDOY at 40, I really do not care if it is really worth $40. I did not check its P/E ratio or other statistics. I only know that it is a growing industry, and Wii will win the third generation market(because people like my mother-in-law is buying one) and thanks to this Forum. That's enough for me. Regardless the stock analysts says it is worth 20 or 30, people will be happy to pay big bucks on top of that.
I still don't know today if it is really worth 40, but the market is willing to pay 73 for it.
On to the fact that investing in stock is for long term...I believe it does not mean buy a stock and leave it there for a long time. It is that you are WILLING to leave it there for a long term. However, if something permanently bad is happening to the company, or some economical event occurred, then you should re-adjust your position. I am WILLING to hold NTDOY for 5 years or when it hits 500, whichever come first. BUT if the general industry are turning South or Nintendo failed its earning targets for a few quarters straight, I may start to sell.
