Currently an analyst at a boutique working on a multi-asset strategy team. While its interesting to research and understand asset classes from a broad top-down perspective, I think I'm getting to the point where I'd like to branch out and specialize in a particular asset class (i.e. equity or credit). I still have limited experience under my belt (~1 yr on the job after graduating from a semi-target, and passing CFA L1 last June).
So my questions are: How doable is it do make this move, and would it warrant moving to the sell-side? Would it require me to re-brand myself by acquiring an MBA? How would potential employers view me?
