Greater fool theory

Greater fool theory

The greater fool theory (sometimes the bigger fool theory, also called survivor investing) is the belief held by one who makes a questionable investment, with the assumption that they will be able to sell it later to "a bigger fool"; in other words, buying something not because you believe that it is worth the price, but rather because you believe that you will be able to sell it to some one else for an even better price.

It might be on some occasions a valid method of making money in the stock market – however, the market participants eventually realize that the price level is too outrageous (too high or too low) and the speculative bubble pops. The bigger fool theory relies on market optimism concerning a particular stock, an industry, or the market as a whole.

The opposite of the bigger fool theory is value investing, which tries to discount market psychology. Value investors such as Warren Buffett believe that it is corporate profits which are the normal returns from stock investments, and any higher return is only possible due to the bigger fool theory.
