Introduction
• The market βs of Sharpe-Litner, and Breedon’s c onsumption βs show little relation of the Cross-S ectional average returns on U.S common stocks.
• Empirical variables determined average returns are: – Size, Leverage, E/P, BE/ME [Banz(1981), Bhandari(19
88), Basu(1983), and Rosenberg, Reid, and Lanstein(1
985)]

Introduction
• If the market is aggregated, there must be so me common factors which can explain both t he common stock market and bond market .
• But for bond market, the factors used to explai n common stock market may not appropriate.
– So, the new variables are introduced in this paper

The Steps for the Experiment
Choose the Data from Database

Sort the data by
“Size” and “BE/ME”

Test the bond factors on market excess return

Test the market factors on market excess return

Test the stock factors on market excess return

Test the stock factors + market factors on market excess return

Test all factors on market excess return Test the adjusted market factors on market excess return To be continued…
