It depends on what you do, banks, investment banks, bond arbitrage, interest rate trading, options and so on. It's good to do all kinds of intermediate business mathematics.

If you don't need any mathematical knowledge, such as stock investment, venture capital and strategic mergers and acquisitions, most of them are qualitative analysis of the project. Philosophy may be more useful.

You don't need to be good at math, but you need to master the basic principles and use them skillfully.

I hope I can help you.
