>>11939499If you want to be a quant, you need to get good at python programming for data science/machine learning, SQL, then learn some C++.
/sci/ has the most “academic” perspective on wall st quants. In real life it involves a lot of hands-on coding, data wrangling and machine learning. Only once you’ve mastered that (and had a few years experience doing it) can you move to more theoretical stuff.
Before you worry about stochastic processes and Brownian motion just get good at statistics for data science and understanding time series. Understanding stats, time series, and the essentials of the financial world is needed for understanding Black Scholes.
I recommend Hull’s Options and Derivatives. It’s not very quantitative but you need to understand like everything in it before you’re actually any use to a financial company.
