The main purpose of this study is to investigate the effects of return interval and investment horizon under the adjustment techniques of both Blume and Vasicek on ISE.

Generally, as the return interval decreases from monthly to daily period, MSE decreases. Generally, as the investment horizon increases, MSE decreases.
