Review Questions

• How does portfolio insurance utilize derivatives to manage risk in investment portfolios?
  • Portfolio insurance uses derivatives like options and futures to create protective strategies against significant losses. By purchasing put options, investors secure the right to sell their assets at a specified price, thus limiting their downside risk. This approach allows investors to dynamically adjust their hedge positions based on market fluctuations, ensuring that they can protect their portfolios while still participating in potential upside movements.
• Discuss the advantages and disadvantages of employing portfolio insurance as an investment strategy.
  • The main advantage of portfolio insurance is its ability to protect against steep market declines, allowing investors to limit their losses. However, this strategy comes with disadvantages, such as potentially capping gains during market recoveries. Additionally, dynamically adjusting positions can be costly in terms of transaction fees and may require constant monitoring of the markets. Furthermore, in extreme market conditions, the effectiveness of portfolio insurance may diminish as it could contribute to increased volatility.
• Evaluate the impact of portfolio insurance on market dynamics during times of economic stress and how it may influence investor behavior.
  • During times of economic stress, portfolio insurance can significantly impact market dynamics by contributing to heightened volatility and increased selling pressure. As investors execute their hedging strategies by selling assets to maintain their risk levels, it can lead to further declines in asset prices. This behavior can create a feedback loop where falling prices trigger more selling, potentially exacerbating market downturns. Consequently, while portfolio insurance aims to protect individual investments, its widespread use can influence overall market stability and investor confidence.
