Efficient frontier maximizes return for a given risk level
Efficient frontier
Efficient frontier maximizes return for a given risk level
The efficient frontier represents the optimal set of investment portfolios. Each point on this frontier offers the highest expected return for a specific level of risk. Investors aim to select portfolios that lie on this frontier to achieve the best possible risk-adjusted returns.
Example
Suppose an investor chooses a portfolio on the efficient frontier with a standard deviation of 10%. This portfolio provides the highest expected return among all portfolios with the same level of risk (standard deviation).
Understanding the efficient frontier helps investors make informed decisions, optimizing their portfolios for maximum return per unit of risk.
