We concluded that the traditional financing model provides a poor description of financial behavior. In contrast, the main idea in behavioral finance is that investing behavior exists and differs from what the traditional financing model assumes. And it affects the financial markets, and improves our understanding of financial decisions and their impact on market prices. That proves that in many cases behavioral finance is better at predicting the behavior of financial markets.enBehavioral financeTraditional financeInvestor behaviorInvestment decisionsArticle
