My major is medicine, but later, because I like securities investment, I switched to a securities company and am currently engaged in investment business.

Your situation is similar to mine. I really want to meet a bosom friend. I changed careers after work. I advanced to a securities company, and I am a graduate student in statistics.

I haven't graduated yet, and I want to take the postgraduate entrance examination, which is easier to handle and take the postgraduate entrance examination in economics. Financial engineering is very hot now. With your skills in microelectronics, it should be no problem to learn some basic economics, especially western economics, including macro and micro, with the previous pre-test review.

If you have graduated, it is convenient to change careers. At present, researchers in securities companies are recruiting not only graduate students in economics, but also talents in various professional fields, such as agricultural researchers, and farmers. Similarly, at present, all listed companies have microelectronics, so it is not a big problem to find researchers in this field. You should learn some basic economics.

The direction of economics is very broad, and financial engineering is the hottest now, because it can be used in stock index futures, quantitative investment and hedging transactions.

In addition, the statistics departments of general economic colleges all have securities and futures majors. Counterpart securities and futures companies.

If you want to work in a bank, you usually study finance, and monetary banking is the most important.

There are also insurance majors, accounting majors and so on.

Personally, I think you have more opportunities to learn from microelectronics to securities investment.
