How do you calculate the beta of two stocks in a portfolio?

Add up the value (number of shares multiplied by the share price) of each stock you own and your entire portfolio. Based on these values, determine how much you have of each stock as a percentage of the overall portfolio. Multiply those percentage figures by the appropriate beta for each stock.

What is the beta of a stock?

Beta is a way of measuring a stock's volatility compared with the overall market's volatility. The market as a whole has a beta of 1. Stocks with a value greater than 1 are more volatile than the market (meaning they will generally go up more than the market goes up, and go down more than the market goes down).Aug 21, 2021

How do you calculate alpha and beta?

Calculation of alpha and beta in mutual funds
  1. Fund return = Risk free rate + Beta X (Benchmark return – risk free rate)
  2. Beta = (Fund return – Risk free rate) ÷ (Benchmark return – Risk free rate)
  3. Fund return = Risk free rate + Beta X (Benchmark return – risk free rate) + Alpha.

How do I find high beta stocks?

  1. Get the historical prices for the desired stock.
  2. Get the historical prices for the comparison benchmark index.
  3. Calculate % change for the same period for both the stock and the benchmark index. ...
  4. Calculate the Variance of the stock.
  5. Find the covariance of the stock to the benchmark.

But there’s one reason to do it manually: the fact that different sources use different time periods in calculating returns. While beta always involves the measurement of variance and covariance over a period, there is no universal, agreed-upon length of that period.

What is beta in investing?

In financial/investment terminology, beta is a measurement of volatility or risk. Expressed as a numeral, it shows how the variance of an asset—anything from an individual security to an entire portfolio —relates to the covariance of that asset and the stock market (or whatever benchmark is being used) as a whole. Or as a formula:

What does it mean when a benchmark has a beta of 1?

If something has a beta of 1, then it really means that, given a change in the benchmark, its sensitivity of returns is equal to that of the benchmark.

How to find variance of an asset?

Find the variance of the asset using =VAR.S (all the percent changes of the asset).

How to calculate beta?

You could also calculate beta simply by plotting the benchmark returns against the stock returns, and adding a linear trendline. Beta is then simply the slope of the trendline.

What is beta in Excel?

This Excel spreadsheet calculates the beta of a stock, a widely used risk management tool that describes the risk of a single stock with respect to the risk of the overall market. Beta is defined by the following equation
