Session 9: Estimating Hurdle Rates - Betas and Fundamentals

New Section

In this section, the speaker discusses the importance of estimating betas in corporate finance and how various company decisions can impact beta values.

Estimating Betas and Company Decisions

• Estimating betas involves fundamental decisions that companies make, such as their choice of business, operational strategies, and financing decisions.

• Regression beta analysis was discussed in the previous session using Disney as an example. The speaker expresses skepticism about relying solely on regression for beta estimation.

• Regression betas are noisy due to standard errors, leading to a range of possible beta values around the estimated figure. This uncertainty is highlighted through examples like Tata Motors' beta ranging from 1.5 to 2.2 based on regression analysis.

• The speaker emphasizes the impact of choosing different market indices for regression analysis by comparing two regressions for Vale against Bovespa and S&P 500, showcasing significant variations in beta estimates.

• Highlighting the variability in beta estimates based on index choices, examples with Deutsche Bank and Baidu are provided to underscore how selecting different market indices can lead to diverse beta outcomes.

Economic Fundamentals Driving Betas

This segment delves into the economic factors influencing betas by examining specific companies' betas alongside their underlying stories.

Economic Factors Shaping Betas

• The discussion shifts towards understanding betas from an economic perspective rather than relying solely on regression outputs by analyzing companies like Bulgari, Seaquest Communications, Microsoft, Fauji, and ExxonMobil to illustrate how business characteristics influence beta values.

• Companies with discretionary products like Bulgari tend to have higher betas due to revenue volatility during economic fluctuations.

• Telecom companies such as Seaquest Communications exhibit high betas attributed to fixed cost structures and substantial borrowing practices that amplify equity earnings volatility across market cycles.

• Microsoft's decreasing beta over time is linked to its growth, diversification, and cash accumulation post-IPO period despite retaining a moderate level of risk exposure.(272s)

Understanding Beta in Business

In this section, the speaker delves into the concept of beta in business, explaining how it is influenced by various factors such as macro risks, product nature, cost structures, and borrowing.

Factors Influencing Beta

• Negative beta acts as a hedge against macro risk.

• Product addiction leads to stable revenues and lower beta.

• Cyclical products result in higher betas; discretionary products lead to higher betas in good times.

• Higher fixed costs amplify company betas during both good and bad times.

• Identifying fixed costs helps determine a company's cost structure impact on beta.

Impact of Debt on Beta

This segment explores the influence of debt on beta, distinguishing between levered and unlevered beta and highlighting the role of debt-to-equity ratios in determining equity betas.

Debt Influence on Beta

• Borrowing introduces fixed costs, impacting a company's beta.

• Levered beta reflects equity risk with debt factored in; tax benefits are considered.

• Regression beta implicitly includes leverage effects based on historical debt-to-equity ratios.

New Section

In this section, the speaker discusses the impact of debt on beta calculations for a company like Disney.

Calculating Beta with Different Debt Levels

• The levered beta for Disney is computed at various debt to equity ratios from 0% to 900%. At 0% debt, the levered beta equals the unlevered beta due to no debt in the capital structure.
