After that, the study of financial investment risk is extended further by constructing the GAS-factor Copula model, and when the parameters of the model are extrapolated, a two-step estimation method is used, i.e., the parameters of the marginal distribution and the parameters of the Copula model are extrapolated separately. Finally, with the help of the GAS-Factor Copula model, the financial investment risk analysis of ML Company can shows that the return on net assets, return on total assets and cost-expense margin of ML Company are lower than the industry average since 2020, and the growth rate of operating income has changed greatly, ranging from -354.88% to 54.3%.
