There are people who believe that "technical analysis" works. I believe in semi efficient markets and do not believe technical analysis works, especially at scale.
I think that quantitative analysis can work in rare casis and generate alpha, but i do not believe that i can predict those cases or generate that alpha myself.
Technical analysis is a bit of a voodoo for me as well, but quantitative analysis works indeed, you just need to spend the time and work on it (as with any other skill in life)
It does until it doesnt. There are very few quant funds that have figured out how to navigate a rapidly changing economic environment. The problem with quant is that it is backward looking. When the market changes most quantitative funds do not have a good method of accounting for the change. They do not properly account for conditioning information and they end up completely hammered.
I am confident that there are people who have at least partially figured out how to invest this way, but i believe it is very, very few. Like less than 10 funds/people on earth.
