Paper trading. Current rules (from 2026-10-31): fixed-January walk-forward 231.31% a year on the research basis, CAGR 214.0%, maximum drawdown -59.8%, on data through 2026-10-28. The inventory-versus-revenue screen was removed on 2026-10-31; the rules before that measured 247.87% on the same data, a gain we no longer trust (see the changelog on the paper page).

A momentum rotation in S&P 500 and Nasdaq-100 stocks with accelerating revenue, plus a gated 3× Nasdaq-100 ETF sleeve, then a quality strip on the stock book.

Flow at a glance

Stages

1. Universe and filters. Point-in-time S&P 500 and Nasdaq-100 members. Trend, accelerating revenue, and balance-sheet screens, using only filings available at the time.
2. Rank. A medium-term over long-term moving-average ratio, highest first.
3. Four stock sleeves. Equal size. Each sleeve re-ranks its picks on its own staggered schedule, less often than it re-weights; on the re-weight days in between it keeps its picks and only resets weights and volatility scaling. A daily check can exit a held name at any time; an admission rule can bring a new leader in without waiting for a drop-out.
4. TQQQ sleeve with a volatility gate. A fixed share of equity while the gate is on, resized monthly. The gate turns the sleeve off when QQQ volatility rises past a set level. It turns back on after volatility falls, or sooner on a FAST re-entry once volatility has come far enough off its off-period peak. Those gate states (on / off / FAST) are the only published TQQQ modes; nothing else is named.
5. Quality strip. A hard balance-sheet screen removes failing names. A softer balance-sheet and accrual screen, plus a gross-margin screen, can cut weight on other failing names; a name already held is immune to that soft cut.

Exact parameter values are not published. Weights in the trade log are % of equity only — no prices or account amounts.
