Greater fool theory

In finance and economics, the greater fool theory states that the price of an asset is determined by whether you can sell it for a higher price, at a later point in time. On assets where the theory applies, it is implied that the asset's intrinsic value is less important than the increase in demand, however irrational it might be. The person buying the overpriced asset later on, for a higher price, is deemed the greater fool.[1][2][3][4]


In times of hyper-inflation and in remote regions the price of necessities is so exorbitant that relative to normal markets these prices may seem arbitrary. Yet the local cost of doing business relative to the price in these regions, as well as the necessity to feed and shelter one's self in a hyper-inflationary crisis, justifies through profit or actual benefit the "foolish" price.

In real estate, the greater fool theory can drive investment through the expectation that prices always rise.[5][6] A period of rising prices may cause lenders to underestimate the risk of default.[7]

In the stock market, the greater fool theory applies when many investors make a questionable investment, with the assumption that they will be able to sell it later to "a greater fool". In other words, they buy something not because they believe that it is worth the price, but rather because they believe that they will be able to sell it to someone else at an even higher price.[8] It is also called survivor investing. It is similar in concept to the Keynesian beauty contest principle of stock investing.[citation needed]

Art is another commodity in which speculation and privileged access drive prices, not intrinsic value. In November 2013, hedge fund manager Steven A. Cohen of SAC Capital was selling at auction artworks that he had only recently acquired through private transactions. Works included paintings by Gerhard Richter and Rudolf Stingel and a sculpture by Cy Twombly. They were expected to sell for up to $80 million. In reporting the sale, The New York Times noted that "Ever the trader, Mr. Cohen is also taking advantage of today’s active art market where new collectors will often pay far more for artworks than they are worth."[9]

Cryptocurrencies have been characterized as examples of the greater fool theory.[10][11][12] Numerous economists, including several Nobel laureates, have described cryptocurrency as having no intrinsic value whatsoever.[13] [14][15][16]
