How to Calculate Volatility
- Find the mean of the data set.
- Calculate the difference between each data value and the mean.
- Square the deviations.
- Add the squared deviations together.
- Divide the sum of the squared deviations (82.5) by the number of data values.
What is the expected return and volatility?
Volatility risk is the unpredictability of investment returns. Volatility risk is measured statistically using standard deviation, which is an estimate of the possible future variance of the actual returns to be generated by the asset class or portfolio around its estimated expected return rate.
How do you calculate expected return and volatility for a stock portfolio?
The expected return of a portfolio is calculated by multiplying the weight of each asset by its expected return and adding the values for each investment. For example, a portfolio has three investments with weights of 35% in asset A, 25% in asset B, and 40% in asset C.
How do you calculate the expected volatility of a portfolio?
The correlation coefficient for Stocks ABC and XYZ returns is 0.64014. Using the formula given above we can now calculate the portfolio volatility: Portfolio volatility = Root(89%2×0.141%+11%2×0.578%+2×89%×11%×0.64014×3.76%×7.60%)=3.93%. Note that this is daily portfolio volatility.
Is a high volatility good?
The speed or degree of change in prices (in either direction) is called volatility. The good news is that as volatility increases, the potential to make more money quickly also increases. The bad news is that higher volatility also means higher risk.
How is volatility calculated?
Volatility is the up-and-down change in the price or value of an individual stock or the overall market during a given period of time. Volatility can be measured by comparing current or expected returns against the stock or market’s mean (average), and typically represents a large positive or negative change.
Is volatility good for returns?
Stock market volatility is generally associated with investment risk; however, it may also be used to lock in superior returns. Larger standard deviations point to higher dispersions of returns as well as greater investment risk.
How to calculate the volatility of a return?
The variance of is now easily derived using the calculated expected value and the variance formula: with for all as the historical probability for each realization equals as written above, thus Using this we can calculate the standard deviation of the random variable or equivalentely the “volatility” of the single-period return by
How to calculate expected return for stock portfolio?
Expected Return for Portfolio = ∑ Weight of Each Stock * Expected Return for Each Stock Expected Return for Portfolio = 25% * 10% + 25%* 8% + 25% * 12% + 25% * 16% Expected Return for Portfolio = 11.5% Let’s take an example of portfolio of HUL, HDFC and 10 year government bond. Expected Return is calculated using the formula given below
How to calculate expected return in Excel template?

How to calculate daily and annualized volatility formula?
The formula for daily volatility is computed by finding out the square root of the variance of a daily stock price. Further, the annualized volatility formula is calculated by multiplying the daily volatility by a square root of 252. How to Provide Attribution? Article Link to by Hyperlinked
