Most people find "true religion" and go on professing that that's the only way forward, be it some technical indicator or high frequency trading.
I flew to Asia recently and the dude sitting next to me was some sort of professional fighter (don't ask who he was since I have no idea, but people were asking him for autographs, so he must be OK at what he does). We chatted for a while and he said something interesting - "I learned judo as a kid and got good at it. But it teaches you to learn other things. You need to learn everything. If you wanna win, you have to kick, punch and grapple. You gonna be better at something, but you need to learn it all."
It sounded to me like a true recipe for success. In finance, you can get good at something specific (quant, fundamental etc), but you have to know that other ways exist and try to internalize/learn as much as you can. Eventually, you will come up with your own unique way that includes bits of everything. It struck me that very few people in any field are willing to adopt this synthetic approach since it pushes them out of their comfort zone.
How exactly do you think "quant guys" cheat?
There is a good reason why everyone is so tight lipped about their methods (btw that covers most market players, including fundamental long short or macro trades). The only real edge in the market is doing something that others aren't and the best way to ensure that is to keep information from spreading around. If you see someone giving away gold, either it's not real gold anymore or they are somehow trying to swindle you.
