A REAL, codeable strategy that reuses the strongest LIVE, non-decayed, non-options deployed winner — cross-sectional relative-strength momentum rotation (majors version Sharpe 2.6) — but on a genuinely DIFFERENT, materially-larger-edge OPPORTUNITY SET: deep-history liquid MID-CAP USD-M perps rather than the 8 majors. This is more than an L24 re-weight: mid-cap crypto exhibits substantially STRONGER cross-sectional momentum and much larger return DISPERSION than the majors (winners and losers separate by tens of percent per week vs single digits for majors), so the relative-strength premium per rotation is far larger relative to the ~0.10% USD-M round-trip — the fee headroom the majors version only marginally has. To control the higher mid-cap drawdown/blowup risk that killed naive long-only baskets, it adds an ABSOLUTE-momentum cash gate (a held slot goes to CASH if that name's own trailing momentum is negative), so in broad mid-cap bear phases the book de-risks toward cash rather than holding falling knives, and conservative per-name caps prevent single-name blowups. Universe = 10 liquid, multi-year-history mid-caps (LTC, ETC, ATOM, ALGO, FIL, EOS, XLM, AAVE, SAND, MANA) — deep enough for a valid backtest, liquid enough to trade. This diversifies the portfolio's heavy majors concentration (single/majors dominate) into a distinct symbol set. NOT the deployed majors rotation (different universe with a documented stronger effect), NOT funding/order-flow/options/reversion. Long-only, diversified top-3, weekly, USD-M. 2 core parameters (momentum lookback, number held).
