Stock prices are weird. The current value is where half the people think the price is too low and half the people think the price is too high. Of course everyone who still has Yahoo stock think that the price is too low--because everyone who thinks the price is too high has already sold their shares.
So everyone who still holds any given stock thinks that the market price is too low.
A simpler explanation is that everyone holding a stock wants it to go up so they can profit. When it goes up to a point where they don't think it's too low, they sell it, and hence no longer own it. So everyone that owns a stock thinks it's too low.
>So everyone who still holds any given stock thinks that the market price is too low.
Only true in a limited sense. For instance, a majority holding the stock up until today might have just thought that the market price was way too high for how the company is performing, but that the presence of one or more misguided, irrational, drowing-in-money, potential aquirers out there meant that there was a large chance they might get a large upside off one of the fools--turns out they were right =).
So everyone who still holds any given stock thinks that the market price is too low.
