The field of behavioral finance has seen incredible growth over the past half century as it has explored the effect that cognitive psychological biases can have on investors’ financial decisions. Behavioral finance stands in stark contrast to the efficient market hypothesis, as it attributes market inefficiencies to investors who are not perfectly rational human beings. It offers a solution to the observed 3.5% gap that active equity investors miss out on in the market compared to passive index funds, which it attributes to their emotions and psychological biases. These common human biases can be grouped into five major categories: heuristics, prospect theory, overconfidence, misperceiving randomness, and herding. This thesis will conclude with applications drawn from the field of behavioral finance that can be applied to both the individual investor and the financial advisor to help achieve better investment returns.
