A financial analyst is reviewing a multiple regression analysis where the dependent variable is the annual return of a stock, and the independent variables include market return, interest rates, and firm size. The regression output shows the following coefficients for the independent variables:
Market Return Coefficient: 0.75
Interest Rate Coefficient: -0.10
Firm Size Coefficient: 0.50
If the analyst wants to interpret the Market Return Coefficient, how should it be understood in the context of the regression analysis?
