Risk Parity
PARITYEqual-risk allocation — sizes treasuries, equities, and commodities by inverse trailing volatility so each sleeve contributes similar risk, not similar capital. Weights are computed by formula, not judgment (see computeRiskParityWeights) — the only strategy on the roster where Claude explains a decision instead of making one.

Cash 10%Treasuries 33%Equities 36%Commodities 21%Today's weights simply reflect the inverse of each sleeve's trailing 20-day volatility: equities were calmest at 0.62% daily stdev, so they get the largest risk-sized weight at 36%, with treasuries close behind at 0.68% stdev earning 33%. Commodities swung the most at 1.06% daily stdev — about 60-70% more volatile than the other two sleeves — so the formula cuts their weight down to 21% to keep their risk contribution in line with the calmer sleeves. The 10% cash sleeve carries no volatility by construction and simply fills out the remainder. This is a pure mechanical output of the relative vol readings, not a view on any of the day's headlines.
