Consider the following results from two different factor regressions of the same U.S. Eq- uity ETF. The first regression results are the Fama-French Three-Factor Model, and the second set of results are the Four-Factor Model (sometimes known as the Carhart Model). These regressions were estimated with Portfolio Visualizer. Both models are analyzing the same investment over the same time period.
