This article applies BEKK express constructive condition in same variables matrix of multi-variables GARCH model from Engle and Kroner (1995) and get the un-equal investment weighted to establish an adjusted un-equal investment portfolio allocation, and then compare to the equal weighted investment portfolio allocation. The real examination researches discover that through the assets combination of NASDAQ index, British Pound vs. US dollar and NYMEX light crude oil futures portfolio, the adjusted un-equal weighted investment portfolio has the phenomenon of volatility grouping and the character of high narrow peak allocation compare to the equal weighted investment allocation, so it has better ability in forecasting the risks than the equal weighted investment portfolio.
