Behavioral Finance

A field of study that looks to explain stock market activity (especially anomalies) thru investor psychology.

As a behavioral finance analyst, Anthony wanted to better understand why stock markets tend to underperform on the first trading day of a week. So, he asked 100 stock traders, "Do you have a case of the Mondays?"

While he did learn 14 new vulgarities and how to dodge eight cups of coffee thrown in his direction, Anthony never was able to explain the Monday Effect anomaly.
