Actually, besides the basic neccesities of life, very little does.
Common stocks, those that pay no dividend in particular, are certainly in the catagory of thingspeople buy that are essentially without intrinsic value. Because all you're buying in essense is a bet on someone else's willingness at some later date to buy your ticket to the magic show. Without that prospect there'd be no market. Why we allow ourselves to be taken in by all the fooh foe rah of earnings, blance sheets, inventories, interest rates, fluctuations in sales and inventories cuz if you ever did stop to think about what a share of stock is really worth in actual terms you'd shun the stock market the same way you'd avoid stepping in front of a bus.
