Asset management salary progression in London

Hello, I am an ambitious student with a passion for investing. I was wondering what is the total comp for an equities analyst in a large AM in London (think Schroders, Axa Investors, Aviva Investors... etc.). I know starting salaries are slightly less than IB, but how about salaries 5-10 years in? How about total comp once you make it to PM?

I have always wanted to be an investor and I am now in my final year at a target school in London and have got full-time job offer from a large asset manager in London. However, given the shift to passive and the voices I heard, I am scared that one cannot truly make it big when starting in asset management, I am passionate about investing but would want to earn ps1m+ in my late 30s and 40s. Can one do that by being a top performer in AM? I also have an M&A offer from a BB bank (Citi/BAML/Credit Suisse) and an invitation to an assessment center for jpm/ms/gs. Should I choose M&A over AM?

I also wondered how easy is the transition from AM to fundamentally driven HF versus doing that switch from IB. If AM comp is capped then moving to an HF could be a way to make more money when performing well and still being in an investing role but I wonder if banking could be better for that than asset management. Given my objective to become a HF PM and eventually starting one, should I start off at a reputable AM or in M&A?

Thank you all!
