The results show that: 1. In the selected four funds, the theoretical risk of three funds is less than that of the actual portfolio fund, and only one fund's risk is higher than that of the actual portfolio fund; 2.

On the foundation of standard UKF algorithm, the ratio of the theoretical value to the practical ones of the innovation's covariance was taken as the input of the FLAC to reduce the dependency of FLAC on the filter model, the generality of the fussy adaptive UKF algorithm was intensified; In the procedure of adjusting the measurement noise's covariance dynamically, the adjusted range could be amplified or minified to different extent by setting the exponential adjusting parameter, so the adjusting velocity and precision of the algorithm was controlled.
