Getting to a good SM from SS ER?
So I'm thinking a bit ahead here but humour me. Right now, if I convert my SA this summer, I will end up in FT SS ER (MS/JPM). If I aspire to work in a decent L/S SM HF one day, will I need to lateral into IB first or is it actually possible from ER?
Also, is it possible to go ER -> MM -> SM? I know MM and SM investment styles tend to be different, so I'm steering towards no.
Edit: I'm in UK if that matters.
