Introduces practical use of entropy = sum p log p to measure uncertainty (coin = 1 bit, fair die ≈2.6 bits, rigged die ≈0.7 bits) and uses penalize mutual information with momentum to force AI trading signals to deviate from pure momentum. Shows portfolio weighting by maximum entropy gives equal weights, uses mutual information to filter redundant alternative-data signals, and reports an options-listing pilot where honoring rare events cuts peak daily volume loss (several days causing ~90% of loss) down to under 20% and improves listing efficiency.
