Summarize the concept of the firm-foundation theory in 3 sentences. 

Source Text: 
[The firm-foundation theory argues that each investment instrument, be it a common stock or a piece of real estate, has a firm anchor of something called intrinsic value, which can be determined by careful analysis of present conditions and future prospects. When market prices fall below (rise above) this firm foundation of intrinsic value, a buying (selling) opportunity arises, because this fluctuation will eventually be corrected—or so the theory goes. Investing then becomes a dull but straightforward matter of comparing something’s actual price with its firm foundation of value. 
In The Theory of Investment Value, Williams presented a formula for determining the intrinsic value of stock. Williams based his approach on dividend income. In a fiendishly clever attempt to keep things from being simple, he introduced the concept of “discounting.” Discounting basically involves looking at income backwards. Rather than seeing how much money you will have next year (say $1.05 if you put $1 in a savings certificate at 5 percent interest), you look at money expected in the future and see how much less it is worth currently (thus, next year’s $1 is worth today only about 95¢, which could be invested at 5 percent to produce approximately $1 at that time). 
Williams actually was serious about this. He went on to argue that the intrinsic value of a stock was equal to the present (or discounted) value of all its future dividends. Investors were advised to “discount” the value of moneys received later. Because so few people understood it, the term caught on and “discounting” now enjoys popular usage among investment people. It received a further boost under the aegis of Professor Irving Fisher of Yale, a distinguished economist and investor.]
