## Variance of stock return calculator

Portfolio variance is a measure of risk, more variance, more risk involve in it. Usually, an investor tries to reduce the risk by selecting negative covariance assets to calculate the standard deviation, variance, mean, sum, and margin of error. For example, in comparing stock A that has an average return of 7% with a 13 Feb 2020 That's the lowest level of risk at which a target return can be achieved. The correlation between the two assets is 2.04. To calculate the covariance What are you trying to find? Usually people want to predict future variance, in which case you should use all of that information, but things like daily high and low

One The term “portfolio variance” refers to a statistical value of modern investment theory that helps in the measurement of the dispersion of average returns of a portfolio from its mean. In short, it determines the total risk of the portfolio. It can be derived based on a weighted average of individual variance and mutual covariance. Variance Calculator Instructions. This calculator computes the variance from a data set: To calculate the variance from a set of values, specify whether the data is for an entire population or from a sample. Enter the observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. You may also copy In the example below, we will calculate the variance of 20 days of daily returns in the highly popular exchange-traded fund (ETF) named SPY, which invests in the S&P 500.

A stock with a lower variance typically generates returns that are Variance calculator and how to calculate. That is not to say that stock A is definitively a better investment option in this scenario, since standard deviation can skew the mean in either direction. While Stock A has a higher probability of an average return closer to 7%, Stock B can potentially provide a significantly larger return (or loss).
