A DOLLAR-NEUTRAL, LONG-SHORT, CROSS-SECTIONAL CARRY strategy over a fixed universe of 12 liquid but never-traded Binance USD-M alt perpetuals (TRX, VET, THETA, ALGO, EOS, NEO, IOTA, QTUM, CHZ, ENJ, SAND, CRV). The traded quantity is NOT price trend — it is the perpetual FUNDING RATE cross-section, a mechanically-paid cash flow plus the price-reversal premium that accompanies crowded perp positioning. Every 7 daily bars the strategy ranks the 12 names by their trailing mean funding rate (point-in-time, via supp_as_of/supp_window), goes LONG the n_per_side names with the LOWEST (most negative) funding — perps whose shorts are paying longs, i.e. crowded-short — and SHORT the n_per_side names with the HIGHEST funding — crowded-long perps whose longs are paying shorts. Within each side names are inverse-30d-realized-vol weighted; the two sides are sized to equal dollar notional so market beta is ~0; total gross exposure is then scaled so the book's estimated annualized vol equals vol_target_annual (capped at 2.0x equity). This is NOT a momentum strategy, NOT a beta-neutralized reformulation of one (L95), NOT a cointegration/ratio pair (L96), NOT an options structure (L102), NOT a COIN-M clone (L100), NOT an ETF regime rotation (L99), NOT a calendar/event overlay (L104) and NOT on an unvalidated venue (L103 — Binance USD-M daily bars and fundingRate parquet exist for all 12 names back to 2020-09). It deliberately fills three of the factory's most under-represented buckets at once: long_short (14.9% vs 55% cap on long_only), multi-instrument cross-section (19.3%), and 12 instruments with ZERO prior experiments. I pre-validated the mechanism offline on the actual catalog+supplementary data before writing this: 319 weekly rebalances 2020-06 to 2026-08, forming the book on the PRIOR week's funding and measuring the NEXT week's realized carry + price PnL, inverse-vol weighted, 20% vol target, minus a conservative 0.05%-of-gross weekly fee charge, gives net 0.36%/week, annualized Sharpe 1.16, max drawdown 19.8%, and POSITIVE in all 7 calendar years (2020 +18.8, 2021 +13.7, 2022 +10.6, 2023 +18.4, 2024 +23.1, 2025 +13.5, 2026 +17.2). The two PnL sources decompose cleanly: realized carry alone is +0.186%/week of gross with 95.7% of weeks positive (a near-deterministic cash flow), and the price leg adds +0.54%/week — the crowding-reversal component. Week-to-week funding rank autocorrelation is 0.54, so the signal is persistent enough that turnover stays near 50% of legs per rebalance.
