Questions & Answers

Q: Who should not invest in total market index funds?

Total market index funds are optimal for the average investor, so those who differ from the average or have specific considerations outside of their portfolio, such as retirees, may want to adjust their portfolio composition.

Q: What is the difference between the market portfolio and the tangency portfolio?

The market portfolio is optimal for the average investor, while the tangency portfolio is the risky portfolio with the highest Sharpe ratio. The tangency portfolio is used in portfolio theory to combine with a long or short position in the risk-free asset.

Q: Why do value stocks tend to be riskier than growth stocks?

Empirically, value stocks are found to be under distress, have high financial leverage, and face uncertainty in future earnings. They are more sensitive to market shocks and tend to deliver low returns in bad economic times.

Q: What are the challenges of deviating from the market portfolio?

Deviating from the market portfolio introduces challenges such as uncertainty about pricing factors, potential trades against skilled active managers, monitoring costs, and the need for more oversight to ensure efficient performance.
