## Calculate beta of stock online

A stock beta (b) is used to describe the relationship between the individual stock versus the market. Stock Beta is used to measure the risk of a security versus the market by investors. The risk free interest rate (Rf) is the interest rate the investor would expect to receive from a risk free investment.

What is Stock Beta? Step 1 – Download the stock prices and NASDAQ index prices for the past couple of years. Step 2 – Sort the data in the requisite format. Step 3 – Prepare an excel sheet with stock price data and NASDAQ data. Step 4 – Calculate percentage change in Stock Prices and NASDAQ. Calculate the stock’s Beta by dividing the covariance of all of percentage change values for both the stock and the index by the variance of the percentage change values for just the stock. To determine the beta of an entire portfolio of stocks, you can follow these four steps: Add up the value (number of shares x 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 Multiply those percentage The Beta is calculated in the CAPM model (Capital Asset Pricing Model) for calculating the rate of return of a stock or portfolio. The Beta calculation in excel is a form analysis since it represents the slope of the security’s characteristic line i.e. straight line indicating the relationship between the rate of return on a stock and the return from the market. Then we need historical stock prices for both. I used this spreadsheet for downloading historical stock data from Yahoo to get daily closing prices for BP and the FTSE index between 3 rd January 2011 and 1 st July 2011. Then we simply calculate the fractional daily returns, as described in the picture below. Note that cell range E8:E108 contains the stock returns and the cell range F8:F108 contains the index returns. Beta Calculation The stock beta definition is the covariance of the stock's price and a broad market index's price divided by the variance of the index price. A stock more volatile than the market has a beta value greater than 1, and one that's less volatile than the market has a beta value less than 1.

### 25 Feb 2016 We have downloaded the historical prices of a stock X and the S&P 500 (date, price) from online and calculated the beta on SQL:

b = (R - Rf) / (Rm - Rf) R = Expected Rate of Return Rf = Risk Free Interest Rate Rm = Expected Market Return b = Stock Beta  A common benchmark used to compute beta is the S&P 500. However, the calculator does not support actual S&P 500 prices, but it does support monthly S&P 500  11 Jun 2019 The overall market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market.
