Buffett used this allegory to illustrate the irrationality of stock price as compared to true intrinsic value.Graham believed that an investor's worst enemy was not the stock market,but oneself. Superior training could not compensate for the absence of the requisite temperament for investing.Over the term,stock price should have a strong relationship with the economic progress of the business.but deaily market quotations were heavily influenced by momentary greed or fear,and were an unreliable measure of intrinsic value.
