PART A Briefly discuss the results from the study. 

PART B What is the relationship between book-to-market and average monthly returns? 

PART C What is the relationship between firm size (that is, market equity) and average monthly returns? 

PART D Which cell in a two-way sort of stocks on size and B/M ratio provides the highest average monthly return? 

PART E What type of problems might an investor expect to face in attempting to purchase stocks in the highest return cell?
