What does quantitative trading in the stock market mean?

Quantitative trading refers to the use of advanced mathematical models instead of artificial subjective judgments, and the use of computer technology to select a variety of "high probability" events that can bring excess returns to formulate strategies, which greatly reduces the impact of investors' emotional fluctuations and avoids making irrational investment decisions under extremely enthusiastic or pessimistic market conditions.

First of all, from the perspective of participants in the global market, according to the scale of assets under management, five of the top six asset management institutions in the world in 20 18 relied on computer technology to make investment decisions, and the scale of funds managed by quantitative and programmatic exchanges was further expanded in 20 19.

Secondly, more than 70% of global capital transactions are conducted by computers or programs, and half of them are managed by quantitative or programmed managers. There will be more than 330,000 related positions when recruiting financial engineers (including keywords such as quantification and data science) on websites abroad.

Third, from the perspective of the training direction of colleges and universities, more than 450 American universities have set up financial engineering majors, and the number of graduates of related majors reaches 6.5438+0.5 million each year. There is a big gap between the market demand and the number of graduates. Therefore, data science, computer science, accounting and related STEM (basic science) students enter the financial industry to engage in quantitative analysis and application development after graduation.

At present, the scale of domestic quantitative investment is about 350-400 billion RMB, including Public Offering of Fund120 billion RMB, and the rest are private quantitative funds, accounting for 3% (more than 9,000 private managers), with an amount of about 200 billion RMB. The overall scale of China securities funds exceeds 16 trillion, of which 14 trillion is public offering and 2.4 trillion is private offering. Optimistically, the scale of quantitative fund management accounts for 1% ~ 2% of domestic securities funds, less than 1% of public securities funds and about 5% of private securities funds. Compared with foreign countries, more than 30% of the funds come from.
