Barra Risk Factor Analysis

What Does Barra Risk Factor Analysis Mean?
A multi-factor model created by Barra Inc., which is used to measure the overall risk associated with a security relative to the market. Barra Risk Factor Analysis incorporates over 40 data metrics including: earnings growth, share turnover and senior debt rating. The model then measures risk factors associated with three main components: industry risk, risk from exposure to different investment themes and company-specific risk.

Investopedia explains Barra Risk Factor Analysis
The Barra Risk Factor Analysis model measures a security's relative risk with a single value-at-risk (VaR) number. This number represents a percentile rank between 0 and 100, with 0 being the least volatile and 100 being the most volatile, relative to the U.S. market. For instance, a security with a value-at-risk number of 80 is calculated to have a greater level of price volatility than 80% of securities in the market and its specific sector.
