CFA is virtually a necessity these days if you want an analyst role or PM role at a mutual fund or other buy-side shop, but do prop trading firms really place any value on it? Can it help you get your foot in the door at one of these firms? For example DRW, or one of the prop trading groups at one of the ibanks? Seems like these types of groups put a greater emphasis on people who are more quants, have a high level of math/physics/engineering, can program and use databases etc. What about a sales trading desk?
