How can the variance of a portfolio be reduced?
Modern portfolio theory says that portfolio variance can be reduced by choosing asset classes with a low or negative correlation, such as stocks and bonds, where the variance (or standard deviation) of the portfolio is the x-axis of the efficient frontier.
What does minimum variance portfolio mean?
Minimum Variance Portfolio is the technical way of representing a low-risk portfolio. It carries low volatility as it correlates to your expected return (you’re not assuming greater risk than is necessary).
How do you find the variance of a three stock portfolio?
To calculate the portfolio variance of securities in a portfolio, multiply the squared weight of each security by the corresponding variance of the security and add two multiplied by the weighted average of the securities multiplied by the covariance between the securities.
What is the mean-variance efficient portfolio?
Mean-variance analysis is one part of modern portfolio theory, which assumes that investors will make rational decisions about investments if they have complete information. In modern portfolio theory, an investor would choose different securities to invest in with different levels of variance and expected return.
What is efficient portfolio?
An efficient portfolio, also known as an ‘optimal portfolio’, is one that provides that best expected return on a given level of risk, or alternatively, the minimum risk for a given expected return. A portfolio is a spread of investment products.
What is variance efficiency?
Mean-variance analysis is the process of weighing risk, expressed as variance, against expected return. Mean-variance analysis allows investors to find the biggest reward at a given level of risk or the least risk at a given level of return.
Where does the minimum variance portfolio take place?
The minimum variance portfolio rests where the line starts to curve and risk is at its lowest level as it relates to return. Anything falling on the efficient frontier line above the MVP is considered an optimal choice (i.e., the expected return lines up with the level of risk).
How can I reduce the variance of my portfolio?
Modern portfolio theory says that portfolio variance can be reduced by choosing asset classes with a low or negative correlation, such as stocks and bonds, where the variance (or standard deviation) of the portfolio is the x-axis of the efficient frontier.

Which is the best example of portfolio variance?
Example of Portfolio Variance For example, assume there is a portfolio that consists of two stocks. Stock A is worth $50,000 and has a standard deviation of 20%. Stock B is worth $100,000 and has a standard deviation of 10%.
How is the level of risk measured in a portfolio?
The level of risk in a portfolio is often measured using standard deviation, which is calculated as the square root of the variance. If data points are far away from the mean, the variance is high, and the overall level of risk in the portfolio is high, as well.
