Introduction
Econometric models are statistical models in econometrics. Investors can use alpha and beta to judge manager’s performance but fund managers had style timing opportunities apart from market timing, such as size, growth and momentum timing. (Car hart, 1997)
The six portfolios meant to minimize underlying risk factor in returns related to size& book-to-market equity. (Fama, et al. 1993)
The variable name and description for regression of CAPM, 3-factor, 4-factor and 5- factor models are:
Variable Names
Description
MF1_RF
Returns of the mutual fund 1
MF2_RF
Returns of the mutual fund 2
RM
Market Index
RF
Risk free rate
RM_RF
CRSP index 1-month T-Bill
SMB
Small (market capitalization) minus big factor
HML
High (book-to-market ratio) minus low factor
MOM
Momentum factor
TRADEDLIQ
Traded liquidity factor
Car hart, Mark M. employed two models of performance measurement: CAPM and 4-factor model. 4-factor model is consistent with a model of market equilibrium. (Car hart, 1997)
CAPM uses a single factor, beta to compare a portfolio with the market as a whole. (Car hart, 1997) RI - RF = αI + βI (RM - RF) + €I
RI : return on stock I
RM : return on market portfolio
RF : risk free rate
