Modern portfolio theory is based on the concept that less than perfectly correlated assets can be combined to maximize what?

• A. Wealth accumulation
• B. Return for a given level of risk
• C. Number of assets in a portfolio
• D. Market efficiency

Answer: (B)

Modern portfolio theory (MPT) fundamentally revolves around the idea of effectively managing investment risk while striving for effective returns. This theory posits that a portfolio composed of less than perfectly correlated assets can lead to a more efficient risk-return scenario, allowing investors to achieve higher expected returns without necessarily taking on a proportional increase in risk.

By combining assets that do not move in perfect tandem with each other, investors can mitigate the volatility associated with any single investment. This means that if one asset's value decreases, another might increase, creating a more stable overall portfolio return. The objective is to optimize the portfolio by selecting a combination of assets that maximizes the expected return for a given amount of risk.

In contrast, wealth accumulation is a broader goal of investing but not a direct focus of MPT, while the number of assets in a portfolio does not inherently correlate with maximizing risk and return efficiency. Market efficiency, on the other hand, pertains to how quickly and accurately information is reflected in asset prices rather than focusing solely on the relationship between risk and return in a diversified portfolio. Therefore, the correct understanding of MPT emphasizes the relationship between return and risk, making the focus on maximizing the return for a given level of risk the correct approach in the context of this
