I just watched a quant documentary and everyone of them said that they can't use math to predict the stock market and those who try with equations just overcomplicate it to the point where they don't even understand what is going on.

They do use math, it's not advanced math but maybe a linear regression of two variables, which makes them a fuck ton of money. The hard part is figuring out the data and what to regress. 'simple' strategies are only simple mathematically. Coming up with them quick enough before they expire is difficult.
