Construction: 

The
Fama/French 5 factors (2x3) are constructed using the 6 valueweight portfolios formed on
size and booktomarket, the 6 valueweight portfolios formed on size and operating profitability,
and the 6 valueweight portfolios formed on size and investment. (See the description of the 6
size/booktomarket, size/operating profitability, size/investment portfolios.)






SMB
(Small Minus Big) is the average return on the nine small stock portfolios
minus the average return on the nine big stock portfolios,







SMB_{(B/M)} =
SMB_{(OP)} =
SMB_{(INV)} =
SMB = 
1/3 (Small Value + Small Neutral + Small Growth)
 1/3 (Big Value + Big Neutral + Big Growth).
1/3 (Small Robust + Small Neutral + Small Weak)
 1/3 (Big Robust + Big Neutral + Big Weak).
1/3 (Small Conservative + Small Neutral + Small Aggressive)
 1/3 (Big Conservative + Big Neutral + Big Aggressive).
1/3 ( SMB_{(B/M)} + SMB_{(OP)} + SMB_{(INV)} ).








HML
(High Minus Low) is the average return on the two value portfolios minus the
average return on the two growth portfolios,







HML =

1/2 (Small Value +
Big Value)
 1/2 (Small Growth + Big Growth). 







RMW
(Robust Minus Weak) is the average return on the two robust operating profitability portfolios minus
the average return on the two weak operating profitability portfolios,







RMW =

1/2 (Small Robust + Big Robust)
 1/2 (Small Weak + Big Weak). 







CMA
(Conservative Minus Aggressive) is the average return on the two conservative investment portfolios
minus the average return on the two aggressive investment portfolios,







CMA =

1/2 (Small
Conservative + Big Conservative)
 1/2 (Small Aggressive + Big Aggressive). 







RmRf,
the excess return on the market, valueweight return of all CRSP firms
incorporated in the US and listed on the NYSE, AMEX, or NASDAQ that have a CRSP
share code of 10 or 11 at the beginning of month t, good shares and price data
at the beginning of t, and good return data for t minus the onemonth Treasury bill rate (from
