# Why are raw and adjusted betas different?

## Why are raw and adjusted betas different?

Betas calculated purely based on historical data are unadjusted betas. However, this beta estimate based on historical estimates is not a good indicator of the future. If the historical or unadjusted beta is greater than 1, then the adjusted beta will be lesser that unadjusted beta and closer to 1, and vice versa.

The adjusted beta is an estimate of a security’s future beta. It uses the historical data of the stock, but assumes that a security’s beta moves toward the market average over time. It weights the historic raw beta and the market beta. The formula is as follows: Adjusted beta = (.67) * Raw beta + (.33) * 1.0.

### Is raw beta levered beta?

Understanding Unlevered Beta A key determinant of beta is leverage, which measures the level of a company’s debt to its equity. Levered beta measures the risk of a firm with debt and equity in its capital structure to the volatility of the market. The other type of beta is known as unlevered beta.

How do you calculate raw beta?

Beta could be calculated by first dividing the security’s standard deviation of returns by the benchmark’s standard deviation of returns. The resulting value is multiplied by the correlation of the security’s returns and the benchmark’s returns.

## What is the Blume Adjustment?

The Blume method is a method used to adjust the market beta. It corrects the estimated market beta of security for its tendency to revert to 1. It adjusts the beta in such a way that the market beta is closer to the expected beta in the future. The Blume adjusted beta is usually referred to as the forecasted beta.

Is Bloomberg raw beta levered or unlevered?

When you look up a company’s beta on Bloomberg, the default number you see is levered, reflecting the debt of that company.

### What does a beta of 0.5 mean?

A beta of less than 1 means it tends to be less volatile than the market. If a stock had a beta of 0.5, we would expect it to be half as volatile as the market: A market return of 10% would mean a 5% gain for the company.

What is a good beta?

A stock that swings more than the market over time has a beta above 1.0. If a stock moves less than the market, the stock’s beta is less than 1.0. High-beta stocks are supposed to be riskier but provide higher return potential; low-beta stocks pose less risk but also lower returns.

## Is levered beta higher than unlevered?

Generally, Unlevered beta is lower than the levered beta however, it could be higher in some cases especially when the net debt is negative (meaning that the company has more cash than debt).

How do you interpret beta?

The beta coefficient can be interpreted as follows:

1. β =1 exactly as volatile as the market.
2. β >1 more volatile than the market.
3. β <1>0 less volatile than the market.
4. β =0 uncorrelated to the market.
5. β <0 negatively correlated to the market.

### What is the fundamental beta?

What is Fundamental Beta? Conversely, a fundamental beta (also know as predicted beta) is derived from current and predicted fundamentals of the company. Different models incorporate various risk factors, such as company size, volatility, momentum, and other value factors, in calculating a company’s fundamental beta.

How do you calculate beta adjusted return?

β = r*sA/sM r is the correlation coefficient between the rate of return on the risky asset and the rate of return on the market portfolio; sA is the standard deviation of the rate of return on the risky asset. sM is the standard deviation of the rate of return on the market portfolio.
