Which beta should we use in different scenarios?

What determines our choices of beta when calculating cost of capital? When should we use levered beta and when should we use unlevered beta? Besides, say a company has a historical beta, under what circumstance can we just use it instead of using industry beta??

we usually (work at a valuation boutique) use forward looking betas, but understand many banks don't do so.

you get the levered beta when looking for it in any popular internet service. What you want to do after that is to unlever the beta - you want to check what is the risk of the firm should it have no debt and be all equity. After that, in your model, either select the average or the median and relever the beta. You would use that beta to calculate the cost of equity.

In general the industry beta is such median or average (make sure to use some sort of choose function in your model)

Hope this helps?

Thanks a lot. Still have a question and would appreciate if you could help. I always wonder why we usually don't use historical beta. I understand that we use industry beta(the unlevered one) as it is a benchmark, implying the average/median risk level the of the players in the industry. By levering it with target firm's current or forwarding capital structure, we get the final beta we use in CAPM model. However, when looking for a benchmark, isn't a firm's historical beta more relevant than the industry one? Why can't we just unlever the firm's historical beta and then lever it with the forwarding equity/debt structure.?

To summarize: you get levered beta from Bloomberg or your own regressions. You unlever the beta's of your peergroup. Take the average/median and subsequently relever with the capital structure of your target company.

If company's activities have changed significantly I agree you could use forward looking beta. Check this website on that under paragraph 4: http://people.stern.nyu.edu/adamodar/New_Home_Page/AppldCF/derivn/ch4de…</a">http://people.stern.nyu.edu/adamodar/New_Home_Page/AppldCF/derivn/ch4de…
