Application of mathematical model in the field of financial investment

With the vigorous development of the international financial industry, more and more new financial products and investment strategies have emerged. Mathematical models with their rigorous logic and accuracy, through in-depth analysis of various data in the financial market, can reveal the laws hidden behind the data and help investors make more intelligent decisions. The wide application of mathematical models not only enriches the theoretical system of finance, but also plays an important role in the actual financial market. It is increasingly recognized that the study of mathematical model has become a key technology in the study of finance, and has played a positive role in promoting the stability and development of financial market.
