# Learn about Barra Risk Factor Analysis.

Barra risk factor analysis is a statistical technique used to identify and quantify the risks associated with investments. The technique is based on the premise that the prices of securities are determined by a variety of factors, including economic, political, and market conditions.

The Barra risk model consists of two components: a factor model and a covariance model. The factor model identifies the underlying risk factors that affect security prices. The covariance model quantifies the relationships between the security prices and the underlying risk factors.

The Barra risk model is used by investment professionals to identify and quantify the risks associated with investments. The model can be used to develop investment strategies and to make decisions about asset allocation. What does Barra stand for? "Barra" is a financial analysis and consulting firm. It is headquartered in New York City.

How long is a Barra? A Barra is a unit of time equivalent to 0.01 seconds.

### How do you calculate Factor return?

There are a few different ways to calculate factor returns. One common method is to use regression analysis to estimate the return associated with each factor. For example, if you are looking at the size and value factors, you would regress the excess return of a portfolio on these two factors. The size factor would be the intercept, and the value factor would be the slope.

Another common method is to use a factor model. In this approach, you would start with a set of return data for a number of assets. You would then estimate the factor exposures for each asset using regression or some other method. Finally, you would use the factor exposures to estimate the return for each asset.

There are a number of different ways to estimate factor returns, and there is no one "correct" way to do it. The approach that you use will depend on your specific circumstances and objectives.
