The Capital Asset Pricing Model is a model that describes the relationship between risk and expected return. Beta is a measure of how sensitive a firm's stock price is to an index or benchmark. Follow these steps to calculate β in Excel: Obtain the weekly prices of the stock; Obtain the weekly prices of the market index (i.e. Therefore, from a portfolio management or investment perspective, one wants to analyze any measures of risk associated with a company to gain a better estimation of its expected return. On the other hand, higher beta stocks are selected by investors who are keen and focused on short-term market swings. This beta calculator allows you to measure the volatility of returns of an individual stock relative to the entire market. The function was first introduced in Excel 2010 and so is not available in earlier versions of Excel. Volatility measures how much the price of a security, derivative, or index fluctuates. Microsoft Excel serves as a tool to quickly organize data and calculate beta. Multiple factors, such as the duration of the period taken into account, are included in the computation of the beta, which creates various results that could portray a different picture. It is an online tool for calculating the probability using Beta Distribution. It may seem redundant to calculate beta, since it's a widely used and publicly available metric. Comment/Request Increase amount of possible repetitions. CAPM formula shows the return of a security is equal to the risk-free return plus a risk premium, based on the beta of that security, Download free financial model templates - CFI's spreadsheet library includes a 3 statement financial model template, DCF model, debt schedule, depreciation schedule, capital expenditures, interest, budgets, expenses, forecasting, charts, graphs, timetables, valuation, comparable company analysis, more Excel templates. Now that we have the results of our regression, the coefficient of the explanatory variable is our beta (the covariance divided by variance). If the opposite is the case, its beta will be a value less than one. Beta Distribution calculator can calculate probability more than or less than values or between a … With Excel, we can pick a cell and enter the formula: "SLOPE" which represents the linear regression applied between the two variables; the first for the series of daily returns of Apple (here: 750 periods), and the second for the daily performance series of the index, which follows the formula: Here, we have just computed a beta value for Apple's stock (0.77 in our example, taking daily data and an estimated period of three years, from April 9, 2012, to April 9, 2015). Templates include Excel, Word, and PowerPoint. This is because their market correlation was much lower, and thus the swings orchestrated through the index were not felt as acutely for those low beta stocks. The second method is to perform a linear regression, with the dependent variable performance of Apple stock over the last three years as an explanatory variable and the performance of the index over the same period. A beta greater than 1 indicates that the firm's stock price is more volatile than the market, and a beta less than 1 indicates that the firm's stock price is less volatile than the market. Download the free Excel template now to advance your finance knowledge! Employing beta strategies can be useful as part of a broader investment plan to limit downside risk or realize short-term gains, but it's important to remember that it is also subject to the same levels of market volatility as any other trading strategy. A beta may produce different results because of the variations in estimating it, such as different time spans used to calculate data. Figure 1 – Beta Distribution. Therefore, incorporating low beta stocks versus higher beta stocks could serve as a form of downside protection in times of adverse market conditions. βa=Cov(ra,rb)Var(rb)\begin{aligned} &\beta_a = \frac { \text{Cov} ( r_a, r_b ) }{ \text{Var} ( r_b ) } \\ \end{aligned}βa=Var(rb)Cov(ra,rb).

The Excel Beta.Dist function calculates the cumulative beta distribution function or the probability density function of the Beta distribution, for a supplied set of parameters. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPMCapital Asset Pricing Model (CAPM)The Capital Asset Pricing Model (CAPM) is a model that describes the relationship between expected return and risk of a security. To get this data, go to: We only provide a small snippet of the data over 750 rows as it is extensive: Once we have the Excel table, we can reduce the table data to three columns: the first is the date, the second is the Apple stock, and the third is the price of the S&P 500. The first is to use the formula for beta, which is calculated as the covariance between the return (ra) of the stock and the return (rb) of the index divided by the variance of the index (over a period of three years). This is a special case of the pdf of the beta distribution. The Cboe Volatility Index, or VIX, is an index created by Cboe Global Markets, which shows the market's expectation of 30-day volatility. Google Finance provides a beta for this company of 5.48, which means that with respect to the historical variations of the stock compared to the Standard & Poor's 500, US CORP increased on average by 5.48% if the S&P 500 rose by 1%. The price-to-earnings ratio (P/E ratio) is defined as a ratio for valuing a company that measures its current share price relative to its per-share earnings. Low beta stocks are much less volatile; however, another analysis must be done with intra-industry factors in mind. The Capital Asset Pricing Model (CAPM) is a model that describes the relationship between expected return and risk of a security. Yahoo! Generally, the index of one is selected for the market index, and if the stock behaved with more volatility than the market, its beta value will be greater than one.
