I like Wikipedia, packrat1...Lemme give you a Wikipedia definition back that is certainly relevant to some RRGI trade strategies. Ever heard of this?...
""Bigger Fool Theory"...From Wikipedia
The bigger fool theory or greater 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 higher price."
