True. In financial markets, even small inefficiencies and impedance mis-matches can be exploited due to liquidity, fine-granularity, high transaction volumes, and uniform standards of measurement. The same principles don't down-scale to the individual athlete or small-group (team) dynamics. Put another way, financial market strategies (in theory) can be constructed on matching/measuring against a continuous variance in capital efficiencies. Human performance is simultaneously less consistent, discrete, and difficult to measure. Put another way, think of matching the torque/horsepower vs. rpm curves for a typical family sedan's engine versus a high-compression race engine. The former can get good performance with an automatic transmission, the later requires a stick shift and an experienced hand on the till.
