The factory's one robust long-only survivor is momentum rotation (majors weekly, Sharpe 2.6), but every equal-weight VARIANT this session died the SAME way — not on the signal, on RISK: the mid-cap equal-weight rotation hit 81.6% max drawdown (hard-abandon), the single-name long-shorts liquidated at -100%. The fix is not a new signal, it is RISK MANAGEMENT. This hypothesis keeps the proven momentum edge but replaces the two things that blow equal-weight rotations up: (1) it ranks by RISK-ADJUSTED momentum (return/volatility, a Sharpe-like score) so it prefers smooth, durable trends over spiky high-vol names that crash; (2) it sizes holdings by INVERSE VOLATILITY and scales total exposure to a fixed PORTFOLIO VOL TARGET, so a single volatile name can never dominate risk and the whole book's drawdown is bounded by construction. It runs on BINANCE_SPOT — filling the under-represented spot venue AND making it LIQUIDATION-IMMUNE (CASH account cannot be liquidated, unlike the three -100% perp blowups). It is genuinely distinct from the pending equal-weight spot rotations (different SIGNAL: risk-adjusted; different SIZING: vol-targeted risk-parity) and from the low-vol rotation (that ranks by vol alone, ignoring trend; this ranks by return-per-unit-vol). Avoids all dead classes: not carry (dead ex-BTC), not a grid (fat-tail), not single-name L/S (liquidation), not options (fragile), not pairs (-82%). Only 3 parameters.
