01How the Top 50 is built

Six stages of statistical and fundamental filtering.

The universe of US-listed equities is enormous — but only a fraction are tradeable as a pair, and only a fraction of those clear our statistical, backtest, fundamental and diversification filters. Which leg is long and which is short is decided by the signal, so every candidate pair is tested once.

1 IN 690candidate pairs makes the final cut≈ 34,500 candidates → 50 selected
  1. 12,000+ equitiesAll NYSE, NASDAQ and AMEX listings
  2. 2,086 equities$2 bn+ market cap, $2 m+ daily traded value, easy to borrow
  3. ~34,500 candidate pairsSame sector and industry sub-sector only (144 sub-sectors)
  4. ~350 pairsCointegration, correlation and five-year layered backtest record
  5. ~150 pairsBusiness fundamentals and valuation metrics fit
  6. 50 Top pairsDiversified across sectors and tickers — no stock appears twice

Equity and candidate-pair counts are from the September 2026 screen. The statistical stage applies an Augmented Dickey–Fuller cointegration test (p-value 0.10 or less), a 50%+ correlation target and the backtest thresholds listed below; the fundamental stage is a hand review for a genuine economic link between the two businesses. A few Wild Cards that miss the statistical filters but show exceptional five-year backtests are added for further study.

02Backtest parameters and results filters

Securities universe & backtest parameters

  • USA-exchange-traded (NYSE / NASDAQ / AMEX), > $2 bn market cap, > $2 million a day average traded value, easy to borrow
  • Fundamentally correlated: same national market, same sector, usually same industry sub-group. Preference for beta- and market-cap-similar pairs
  • Five-year backtest lookback period
  • 60-day standard deviation and moving average of Core Ratio lookback settings
  • Backtested with two layers: Leg 1 at ±2.5σ entry stretch for $5,000 per leg; Leg 2 at ±3.25σ for a further $5,000 per leg. Both exit together at a ±1.0σ exit stretch on the moving average of the Core Ratio
  • Position-sized at $5,000 per leg for each layer. We suggest you paper-trade first, or lower leg size substantially, while learning the software and the system
  • 0.10% commission and slippage per trade, based on Interactive Brokers’ average execution costs
  • Maximum 50 days in trade — our time stop

Results filters applied

  • Cointegration: Augmented Dickey–Fuller test; we generally select only pairs with a p-value of 0.10 or less. UA3 shows this as Reverse Cointegration (1 minus the p-value), so we look for 0.90 or greater; 0.88+ is within tolerance
  • Correlation: target 50%+. Lower correlation is tolerated if the pair is strongly cointegrated and scores highly on every other criterion, or for Wild Cards
  • Minimum average profit per trade: $200, preferably $300+. Minimum 8 trades over five years. Compound annual growth rate of net profits, self-financed (before leverage), preferably in excess of maximum drawdown — positive reward-to-risk. Maximum drawdown < 20%, preferably < 15%
  • Win rate: at least 70%, target above 80%
  • Total commission and slippage: less than 20% of gross profit
  • Wild Card pairs: a few pairs that miss our correlation and cointegration filters but show exceptional in-sample backtests over the last five years. We think they merit further study of their signals
Autoload in UA3: Upper Watchlist Toolbar → Autoload → “Autoload US Equities Pairs.” The September 2026 vintage downloads to your instance immediately and sits alongside the previous set. Before trading a pair that is new to you, open its five-year history in UA3 and satisfy yourself that you agree with our selection. Familiarity is part of the edge.

03What the fifty did in the backtest

Hypothetical backtest results — not live trading, not out-of-sampleEvery figure below comes from backtested signals over the same period in which these pairs were selected. No account traded these results, and nothing here is an out-of-sample or walk-forward test. Live trading rarely matches a backtest: fills, slippage, data errors and regime changes reduce returns and increase drawdowns.

$5k legs, profits swept (no compounding), after 0.10%/leg costs and margin interest. S&P 500 = SPY with dividends reinvested. Backtest results, not promises.

We measure the vintage the conservative way: a $100,000 account, fixed $5,000 legs (5% of equity; 10% when the second layer fires), profits swept as made so returns never compound, after 0.10% per leg commission and slippage and IBKR margin interest. The S&P 500 comparison is buy-and-hold with dividends reinvested — it compounds, the pairs are not allowed to.

On that basis the fifty produced 817 closed trades over five years, a win rate of 89.4%, and an average return of 50.3% a year on $100,000 — positive in every twelve-month period, including 2022, when the S&P 500 lost 16.6%. The book ran at 0.98x average leverage and never exceeded 2.7x.

The four-page tear sheet has the year-by-year table, the equity curve against SPY, the leverage profile, a Monte Carlo risk-of-ruin analysis, the tail scenario a backtest cannot show, and a partial out-of-sample check on the nine pairs carried over from earlier vintages.
