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

  2. @Ann I’ve emailed you a spreadsheet. The old spreadsheet I had up was corrupt so I removed it, then promptly changed laptops and lost it.

    In the meantime the best spreadsheet I’ve found for Beta Coefficient Calculation is at Money-Zine.com. You can download a spreadsheet from there.

  3. May you please send me your excel spreadsheet with formulas to calculate beta coefficient. Thanks in advance for your help. Rgds

  4. Hey Paul Zag! Long time no speak!
    Was wondering if you still had that beta spreadsheet. Finishing off my BBus (Financial Planning) and need to calculate Beta for a company… and do all the other gear. Anyways, if you could shoot thru an email, it’d be great. I checked the website you suggested, but it’s just got the CAPM calculator that requires you to already have a value for beta…. which of course is what I’m trying to ascertain.

    Hope to hear from you soon mate.
    Cheers

  5. Hi Paul, could you please email me the spread sheet on beta coefficient. Hope to hear from you soon, any thanks.

  6. I’ve just about finished rebuilding the spreadsheet and am making available for testing. Everyone who’s left a comment so far should have received a spreadsheet from me, but the latest version has only been available this week so @Allan and @kim got it.

    Anybody else who wants to test it can comment here and I’ll email them the current version.

    Once it goes live it will be available for free but you’ll have to register with a valid email address to get it. I wont be spamming you, just want to know who’s using my work.

  7. Hi Paul. Would you mind resending the beta spread sheet please to my new email address above, my partner mistakenly deleted it. Many thanks Kim
