Market crash

Review Questions

• How does investor sentiment influence the occurrence and severity of a market crash?
  • Investor sentiment significantly impacts both the occurrence and severity of a market crash. When investors lose confidence in the market due to negative news or economic indicators, they may engage in panic selling. This rush to sell can lead to a rapid decline in stock prices, creating a feedback loop where falling prices further diminish confidence and provoke even more selling. Understanding this relationship is crucial when assessing risk and return potential during volatile periods.
• Discuss the regulatory measures that can be implemented to mitigate the effects of a market crash and their effectiveness.
  • Regulatory measures like circuit breakers are designed to mitigate the effects of market crashes by temporarily halting trading when prices drop dramatically within a short period. These measures aim to prevent panic selling and give investors time to assess information before making decisions. While they can help stabilize markets temporarily, their effectiveness often depends on the underlying causes of the crash and investor behavior once trading resumes.
• Evaluate the long-term implications of a market crash on investor behavior and risk-return dynamics in financial markets.
  • A market crash can have profound long-term implications on investor behavior and risk-return dynamics. Following a crash, many investors may become more risk-averse, opting for safer investments like bonds rather than equities. This shift can alter capital allocation within financial markets, potentially leading to lower overall returns in the stock market as capital flows out during periods of uncertainty. Additionally, investors' experiences during crashes often lead to lasting changes in investment strategies and preferences for risk management.
