periods of time, it is evident that peaks in this index generally present good buying opportunities. Another example of a simple contrarian strategy is Dogs of the Dow. When purchasing the stocks in the Dow Jones Industrial Average that have the highest relative dividend yield, an investor is often buying many of the "distressed" companies among those 30 stocks. These "Dogs" have high yields not because dividends were raised, but rather because their share prices fell. The company is experiencing difficulties, or simply is at a low point in their business cycle. By repeatedly buying such stocks, and selling them when they no longer meet the criteria, the "Dogs" investor is systematically buying the least-loved of the Dow 30, and selling them when they become loved again eventually. When the Dot com bubble started to deflate, an investor would have profited by avoiding the technology stocks that were the subject of most investors' attention. Asset classes such as value stocks and real estate investment trusts were largely ignored by the financial press at the time, despite their historically low valuations, and many mutual funds in those categories lost assets. These investments experienced strong gains amidst the large drops in the overall US stock market when the bubble unwound. The Fidelity Contrafund was founded in 1967 "to take a contrarian view, investing in out-of-favor stocks or sectors", but over time has abandoned this strategy to become a large cap growth fund. Relationship to behavioral finance Contrarians are attempting to exploit some of the principles of behavioral finance, and there is significant overlap between these fields. For example, studies in behavioral finance have demonstrated that investors as a group tend to overweight recent trends when predicting the future; a poorly performing stock will remain bad, and a strong performer will remain strong. This lends credence to the contrarian's belief that investments may drop "too low" during periods of negative news, due to incorrect assumptions by other investors, regarding the long-term prospects for the company. Furthermore, Foye and Mramor (2016) find that country-specific factors have a strong influence on measures of value (such as the book-to-market ratio). This leads them to conclude that the reasons why value stocks outperform are both country-specific and behavioral.
