Calculate the Beta Coefficient of a stock

Beta CoefficientAs part of the Corporate Finance subject of my MBA we have to calculate the beta coefficient (aka Beta) of a company’s share price. The is applied economics and market mathematics, but it simply is a number which indicates how closely (or not) a company’s share price moves in relation to a broader market (or an index like the S&P ASX200 or the Dow Jones Industrial Average).

Anyway, part of the process is to create an excel format spreadsheet to aid with the calculation. I’ve done it and thought I share it with you. It will work with any spreadsheet program that can open .xls files

    1. The zip file contains a single excel spreadsheet. The first tab of the spreadsheet contains notes.

      Read the notes, follow the instructions, update the data and it will show you the Beta Coefficient of your security.

  8. Please leave a comment if you can’t get the spreadsheet. I’m reviewing the delivery method. Ideally I want to email the spreadsheet to you, but the plugin I use doesn’t do that well..

    Most comments will be moderated so wont show up immediately. But I do see them all.
