Top algorithmic/quantitative HFs in London?
Which algorithmic/quantitative hedge funds with offices in London belong to the set of most prestigious (with the best reputation) HFs world-wide? (i consider "hedge fund" in a broader sense: prop shop, investment manager, market maker, ...)
From some recruiters I got impression that Jane Street, GETCO, G-Research and GSA Capital top the list in London, but out of these 4 only Jane Street and GETCO are in fact international. I would like to hear other opinions.
Which one do you think would be the "safest" first career option for after a PhD?
