This study evaluates the effect of three factors: firm’s profitability, interest rate, and beta, toward the stock prices movement of 32 property stocks listing at Jakarta Stock Exchange (BEJ). Path analytical model was designed with interest and return on asset (ROA) profitability as the exogenous, stock beta became an intervening variable and average rate of stock prices movement became an endogenous variable. Daily prices for the stocks, BEJ Composite Index, profitability, and interest rate were obtained from BEJ and Bank Indonesia tapes for January 2000 to December 2004 period. This analysis indicated that the stock prices movement was the most dominant influenced by beta followed by interest rate (negative) and firm’s profitability.
