r= rf + B,MKT + B,BMS + B,HML
where B is beta for each respective factor
MKT is the standard market premium
BMS is the size premium factor; Big minus small (the return from shorting large caps and investing those in small caps)
HML is the Value Premium factor, High Minus Low (the return from shorting high market to book value stocks, and investing them in low market to book value ratio stocks)
Pasteur Strambaugh is the same thing, but it has a liquidity premium factor as well. As you could guess, that factor is the return that would result from shorting high liquidity investments, and investing them in low liquidity investments |
