Aswath Damodaran – Session 9 (Undergraduate): Determinants of Betas

Published on Feb 24, 2016

Betas measure only non-diversifiable or market risk and not total risk (explaining why Harmony can have a negative beta and Philip Morris a very low beta).

1. Betas are determined in large part by the nature of your business. Products and services with elastic demand should have higher betas than products with inelastic demand. And if you do get a chance, try to make that walk down Fifth Avenue…
2. Your cost structure matters. The more fixed costs you have as a firm, the more sensitive your operating income becomes to changes in your revenues.
3. Financial leverage: When you borrow money, you create a fixed cost (interest expenses) that makes your equity earnings more volatile. Thus, the equity beta in a safe business can be outlandishly high if has lots of debt.
