The typical person owns a part of a company in order to gain some financial advantage.
The financial reward is either a dividend or an increase in the share prices (or both).
Many naive investors (and many who are forced into baskets of stocks in 401Ks in the US) own shares in what amount to moribund companies that are both not growing (in the stock valuation sense) and not throwing off dividends. This is folly, a sheer waste of investment, one might as well stuff the mattress with euros and greenbacks.
Indeed, with the pathetically low cost of borrowing today, it is an excellent investment to use borrowed cash to buy stock in companies throwing off reliable dividends. Do you sense a bubble? Indeed you do, but few investors, even the "hot cash" ones, have a big enough todger to take the plunge (for foolish reasons they seem to still cower in the negative return Treasuries). Well, she is waiting-- and if you can borrow long it is nearly a no lose situation (one can hedge out the potential for a base stock loss, but this reduces the fat bottomed payback).
One can be a fluffy being fleeced, or be a wolf running through the emasculated sheep flock. If you don't ride the bubble up you'll miss out-- AGAIN! If the FED and the ECB and the BoJ want to load money at far less than the dividend pay back rate, well, what is anyone waiting for?
