Review Questions

• How does portfolio insurance utilize put options to protect an investment portfolio from market downturns?
  • Portfolio insurance employs put options as a protective measure against declines in the value of assets within an investment portfolio. By purchasing put options, investors acquire the right to sell their underlying assets at a predetermined price, effectively setting a 'floor' for potential losses. This strategy allows investors to remain invested in their assets while safeguarding against significant market declines, ensuring that their capital remains protected.
• Evaluate the advantages and disadvantages of using portfolio insurance as part of a broader investment strategy.
  • The advantages of using portfolio insurance include the ability to limit losses while still participating in market gains, providing peace of mind during volatile periods. However, disadvantages include the costs associated with purchasing put options, which can eat into overall returns. Additionally, in rapidly falling markets, the demand for put options may increase, potentially leading to higher premiums and reduced effectiveness of the strategy. Thus, while it offers risk mitigation, investors must weigh these factors carefully.

  • Changes in market conditions can significantly influence the effectiveness of portfolio insurance strategies. In highly volatile markets, there may be increased demand for put options, resulting in higher premiums and potentially diminishing returns on investment protection. Additionally, liquidity constraints could hinder timely execution when investors need it most. Therefore, when implementing portfolio insurance, investors should consider factors such as market volatility, option liquidity, and their overall investment goals to ensure that they are adequately protected without incurring excessive costs.
