Review Questions
How do arbitrageurs impact market efficiency?
Arbitrageurs impact market efficiency by exploiting price discrepancies between different markets. When they buy low in one market and sell high in another, they help eliminate these inefficiencies by driving prices towards their true value. This process ensures that information is quickly reflected in asset prices, ultimately contributing to a more efficient market where similar assets trade at similar prices.
Discuss the relationship between arbitrageurs and derivatives in financial markets.
Arbitrageurs often use derivatives as part of their trading strategies to enhance their ability to capitalize on price discrepancies. Derivatives allow them to take positions based on the expected future price movements of an underlying asset without having to own it outright. By utilizing options or futures contracts, arbitrageurs can effectively hedge their risks while simultaneously engaging in arbitrage activities across different markets.

This rapid execution allows traders to take advantage of fleeting price discrepancies before they vanish, maximizing potential profits. As a result, technology not only increases competition among arbitrageurs but also plays a crucial role in ensuring that financial markets remain efficient and responsive to new information.
