Constructing multi-assets option portfolio is an efficient way of risk management and gain profit. This article focuses on the Black-Scholes-Merton(B-S-M) option pricing method of rainbow option and spread option and fits the ARIMA price prediction model. The data for one year is collected as the training set for ARIMA model and the historical volatility estimation. The B-S-M model takes historical and future forecast data into consideration, and find a good estimation for parameters. The Monte Carlo method is utilized for option pricing which contains the measure transform form risk-neutral measure to reality measure. ARIMA models fit subseries well with overall residuals evaluated as normal and the significant model parameters. According to the analysis, investors can forecast the market trend accurately and find the best portfolio. These results offer a guideline for the portfolio design with large net price gap in futures market.
