Review Questions

• How do arbitrageurs contribute to market efficiency, and what impact do they have on price discrepancies?
  • Arbitrageurs contribute to market efficiency by identifying and exploiting price discrepancies across different markets. When they buy an asset in one market and sell it in another at a higher price, they help align the prices of that asset across markets. This activity reduces the likelihood of sustained price differences, ensuring that markets react quickly to new information and maintain consistency in asset valuations.
• Discuss the tools that arbitrageurs use and how derivatives can enhance their strategies in capitalizing on market inefficiencies.
  • Arbitrageurs often utilize derivatives such as options and futures to enhance their strategies in capturing arbitrage opportunities. These financial instruments allow them to take positions in an underlying asset without needing to commit large amounts of capital upfront. By using derivatives, arbitrageurs can hedge their risks while simultaneously profiting from discrepancies in pricing across various markets, thus leveraging their trades for maximum efficiency.
• Evaluate the risks associated with arbitrage trading, particularly in relation to market volatility and execution issues.
  • While arbitrage trading is generally perceived as low-risk due to its nature of exploiting price discrepancies, it is not without its challenges. Market volatility can rapidly change the price dynamics, leading to potential losses if an arbitrageur is unable to execute trades at expected prices. Additionally, execution risk arises when there are delays or failures in order placements, causing missed opportunities or unfavorable pricing outcomes. Thus, while arbitrageurs aim for risk-free profits, they must be mindful of these inherent risks.
