Which of the following best describes arbitrage?

• A. Investing in long-term assets
• B. Buying and selling securities simultaneously in different markets
• C. Leveraging investments through margin trading
• D. Buying securities with guaranteed returns

Answer: (B)

Arbitrage is best described as the practice of buying and selling securities simultaneously in different markets to take advantage of price discrepancies. This activity allows traders to profit from the difference in prices for the same asset across various markets, effectively ensuring a risk-free profit. The core principle behind arbitrage is that market inefficiencies create situations where an asset can be purchased at a lower price in one market while being sold at a higher price in another.

In this context, the other options do not accurately define arbitrage. Investing in long-term assets involves holding investments over an extended period, while leveraging investments through margin trading refers to borrowing funds to increase the potential return on investment. Buying securities with guaranteed returns is indicative of a low-risk investment strategy rather than a trading strategy that exploits market inefficiencies as seen in arbitrage. Therefore, the description of arbitrage aligns closely with the simultaneous buying and selling of securities across different markets.
