Conduct some research on behavioral finance and how it relates to investment decision-making and portfolio risk. Address the following:

• Present a theory related to behavioral finance (examples are herd mentality, castles in the air theory, or behavioral biases). Include the title of the theory, the theorist/founder (if known) and a brief overview of what the theory states.
• Explain how this theory applies to investment risks and return for a portfolio (for an individual) or an organization's overall financials (for a business).
• How does the behavioral side of finance relate to the quantitative data that we have reviewed this week? Is this a negative or positive relationship?
