Behavioral Finance

Background & Context Behavioral finance examines how psychological factors such as emotions, cognitive biases, and social influences affect financial decisions – thereby disproving the assumption of rational market participants.

Added to this is the anchoring effect: we are dazzled by numbers once mentioned (e.g., the purchase price) and ignore new information. Overall, behavioral finance shows that we are not perfect calculating machines, but rather make systematic …
