Ma Jinfeng's analysis of soybean and soybean meal futures contracts in 2011 showed that there is a strong correlation between the two, so there is a certain causal relationship between their price changes, so they judge the opportunity for arbitrage in the two varieties and use the unit root The test verifies that the first-order single-integer relationship is consistent between the two varieties. The cointegration analysis shows that there is a strong cointegration relationship between the two, which meets the effective equilibrium condition, and the price difference between the two varieties changes significantly. Therefore, the price difference between the two has a long-term stable regression characteristic, which can be arbitrage through asset portfolio Trading investment.

Ma Jinfeng in 2011 through the analysis of soybean and soybean meal futures contract, indicating that there is a strong correlation between the two, so there is a certain causal change in the price change, so judge the opportunity of arbitrage in the two varieties, and use unit root detection to verify the two varieties in line with the one-order single-order relationship. Through the cointegration analysis, there is a strong cointegration relationship between the two, in line with the effective equilibrium conditions, and the spread between the two varieties change significantly, so the spread between the two has the characteristics of long-term stable regression, through the portfolio and carry out arbitrage trading investment.
