Guessing Stock Prices

I reckon that, if one stares at historical stock prices, one can have a fun time trying to guess where the price goes next. Indeed, if we have weekly stock prices for some DOW stock (for example), over, say, 32 weeks ... then it'd be great fun to see if we can stare at the price chart, look carefully at the prices themselves, apply one or more of the sexy techniques we find here ... then guess at the price 4 weeks into the future. It's a game, eh? Anyway, it's entertainment for me and the game is described here.
