First, girls' mathematical operation ability is relatively weak, but now financial research does not leave mathematical modeling and statistical measurement, and even needs to master various programming skills to deal with complex and difficult operations, so girls have no advantage (unless you are super good at science, talented girls rule out this concern);
Second, girls lack professional sensitivity to finance, because we pay too little attention to economic hotspots. We don't read books or newspapers, but only watch entertainment news and talk about shopping online. It is rare to find girls staring at financial news and the stock market.
The last thing I want to tell you is, don't say whether it is suitable for any major, but whether you like it or not. I was very ignorant when I chose my major in the past. I felt that finance was hot and my future employment prospects were good. I chose this major without knowing anything, but later I found that I really didn't like it. Teachers around me often say that girls should not learn this, because they are too tired and bored. If you really want to study, you can study financial history. Choose others carefully!
