I look at the stock market the same as I look at gambling, like Mike said. If you can afford to lose it, then play.
The way I see it is that they are at nearly their lowest point in 5 years right now as far as stock value is concerned. If you dont' think that they'll "close down", then right now, this stock is seriously "on sale".

(Excuse the shopping analogy.. it's in my blood as a woman). If you're willing to sit on it then I say buy it. Right now the stock is trading at $2.73 a share... you invest $10K and the stock just jumps to $10.00 a share after a year or so... that's a $26,600 profit... not too shabby.
Again, my two cents...

and totally not my field of expertise! haha
Any financial planners or stock brokers on here??
