It doesn't - assuming that there is, in fact, a correlation between digit ratio and testosterone levels, it probably implies nothing more than that high testosterone levels are necessary to impress the decision-makers in trading companies. It's an interesting correlation, but it pretty much follows from high testosterone levels -> low digit ratio and high testosterone levels -> high trader salary It makes sense that small differences in some personal characteristic leads to large differences between the compensation of traders. The interesting question is whether slightly higher testosterone levels cause ten times better performance over time (or even enough of a performance improvement to justify a ten times greater salary). This seems like a ludicrous claim. But it's really funny if this is, in fact, what the market implicitly expects from its traders.
