Monthly data are used. MKT is the benchmark’s excess return over one-month LIBOR USD; HML is the difference in monthly performance between the S&P 500 Value and Growth Indices; SMB is the difference in monthly performance between the smallest 30% and the biggest 30% of stocks in the index (in terms of weights); and Intercept is a monthly excess return.
