Although computers and finance are easily associated with quantitative investment, remember that quantitative investment is only one direction in the financial field! Its essence is to find a strategy with statistically positive expectation. Then you can't avoid the tearing of Bayesian and frequency school. No matter what guiding principle you use to invest, remember, this is definitely dirty work. You have to endure the pain of strategic failure, you have to know yourself every day and deny yourself. I feel anxious every day. Any qualified graduate can produce a large number of strategies in a short time. But putting money into management is a qualitative leap, and how many researchers died here. Some time ago, I chatted with Feng Bo, a generous boss. He said that the essence of the secondary financial market is a semi-information market. In the places where the public is right and the old woman is right, some people make money from the Book of Changes, some people make money from inside information, and some people make money from quantitative tools. Finally, it depends on the results, so all posted strategies need time to verify. If you are not a confident person in adversity like Hanamichi Sakuragi, you might as well calm down and do something for this industry. On the contrary, it is easier to live a sense of wealth and accomplishment. The financial industry is the place that needs the most time to verify the value.
