Analysis (prediction) belongs to analysis and operation belongs to operation. It is difficult to make a lot of money by analysis and statistics alone.

Stock involves a wide range, so analyzing the stock market in different ways is essentially to study the law of stock price rise and fall from different angles.

And mathematics studies regularity from one angle. Further research (such as the model designed by rocket experts on Wall Street) is a matter of probability.

So many economists and mathematicians can be analyzed, but they can't make money in the stock market. This is because they only focus on some factors in the stock market, and the stock market specialty covers a wide range, and they need an all-rounder (including psychological quality) to become a winner.
