It has something to do with mathematics, but it is not absolute obedience?
First of all, the compilation of technical indicators needs mathematics?
Secondly, when doing fundamental analysis, we need to use mathematical knowledge to build a model, and then calculate its theoretical value as a reference for investment. ?
Finally, the reason why we need mathematical knowledge to calculate some commonly used price rises and falls is because we don't absolutely obey mathematics, because any index or stock valuation model can't accurately calculate the value of the stock itself, because there are many uncertain factors in the future, and these uncertain factors can't be reflected in the model, so stock investment should not be superstitious about the results of theoretical stock models such as mathematics, but should judge whether the stock has purchasing value according to experience and various knowledge.
