Quantitative investment is based on the result of rational analysis of data. In fact, the market is irrational most of the time. For example, the historical data of A futures is very good, and it is worth buying after quantitative analysis, but the market trend is always irregular (short-term and long-term). You don't know that a heavy rain may cause corn to fall.

The data made by quantitative investment is very beautiful, but in fact, few people dare to follow the strategy, because the changes in the market are strange and unpredictable.

Quantitative investment in stocks is more reliable (basically no one uses it, at first glance, the income is very high, and the actual operation is very miserable), and the futures risk is too great. The reason is that stocks are backed by listed companies. As long as the fundamentals and finances of listed companies are fine, some fluctuations are controllable at most.

Futures are different, just like crude oil a while ago, which fell into negative numbers. Who dares to think? Without a reliable futures endorsement, no one can guarantee that your corn will be flooded before the contract expires.
