Campbell and Company

Campbell & Company was running systematic futures programs in 1972, before most quant firms had founders, let alone computers. Five decades on, the Baltimore manager still trades client capital on models rather than hunches.

Its flagship spreads risk across trend following, systematic macro, short-term trading, and equity market neutral, with roughly half the budget now in relative-value approaches instead of pure trend. Campbell calls its method Collective Intelligence: human judgment wired into quantitative tooling. The firm has stayed small and notably loyal, much of its staff measured in decades rather than years, and it reaches allocators through both a US mutual fund feeder and a UCITS vehicle, broad distribution for a CTA of its vintage.
