Yilin Wang, MIT mathematician and one of the leading minds on the geometry of randomness:
“there is a precise number for how far a shape is from pure chance. Citadel pays $500,000 to people who compute it instead of guessing it.”
her field is the mathematics of random curves. flip enough coins and the path they trace is not shapeless. it has a precise geometry, and a number, the Loewner energy, that measures how far a curve sits from pure chance.
a circle scores zero. it is the most natural thing randomness can draw. almost every shape you see on a chart scores near zero too. it is noise wearing a costume.
this is the entire quant problem in one idea. the market draws millions of random curves, and only a vanishing few carry real structure. the edge is a rigorous way to tell the costume from the signal.
Citadel pay $500,000 a year for people who can measure that difference instead of feeling it.
the trader who falls in love with a pattern is admiring a curve that randomness would have drawn anyway.
the shape was never the edge. the odds that randomness did not draw it were.
