Advice: Top Tier US Business School > London Asset Management Role

WSO, I'm currently an MBA at a top tier US school trying to switch into investment management (either MF or HF, public equities). I had an investing summer internship (at a strong brand name), but that was my first professional investing experience. I'd like to move back to London after school (I'm from the UK), but I'm concerned that MBAs aren't as valued in applying to investing jobs in London or there aren't the same opportunities. Do you think this is true? Do any of you have advice for me in targeting my search?

Best, C
