You asked for it: New download on the ‘pitfalls of beta’

BVWireIssue #124-1
January 3, 2013

Prompted by a subscriber’s request, we asked the editor of the Journal of Applied Corporate Finance to republish an article from its current issue, “The Pitfalls of Levering and Unlevering Beta and Cost of Capital Estimates in DCF Valuations,” that was cited in the most recent BVWire.

As you’ll recall, the article, by Robert Holthausen (University of Pennsylvania) and Mark Zmijewski (University of Chicago), reviews the “routine steps” of quantifying beta in common cost of capital models and concludes that the “levering and unlevering formulas … are not appropriate for valuing many companies.” In fact, the authors say, substantial valuation errors can result from assuming the betas of debt and other preferred securities are equal to zero and/or ignoring the effects of equity-linked securities, such as employee stock options.

The editors and authors graciously agreed to our request, and the complete article is currently available at our free downloads page. By the way, the authors will have a new release of their book Corporate Valuation: Theory, Practice and Evidence (Cambridge Publishers) coming in February 2013. We’ll feature more information and a link to the hardcover edition soon.

Please let us know if you have any comments about this article or enhancements you would like to see.
