Market-neutral stock selection that beat T-bill + 4%

Before and after costs, Jan 2021 – Aug 2026. Returns come from picking stocks, not from the market.

Thesis 1Rank, don't predict the market

Each month we rank ~3,000 U.S. stocks by expected return beyond what their market exposure delivers.

Thesis 2Five forecasters, one score

Ridge, LightGBM, a pre-trained neural net and two SEC 8-K filing signals make different mistakes; averaging cancels noise.

Thesis 3Matched on risk

Longs and shorts are paired inside 20 projected-beta groups, so the book carries almost no market risk.

Process

Investment process: from signal to execution

Every layer has a rationale grounded in published research. The signal fires at month-end, the book is rebuilt, and orders go out before the close.

Risk

Risk management process

Concentration, market cap, illiquid positions, drawdown and ratios, plus the tests that show the returns are not luck.

No single name, or small group of names, can sink the book.

Arcana, 31 Aug 2026
  • Near-equal weights (~0.43% of NAV) instead of an optimizer, so no estimate error concentrates the book.
  • Longs and shorts are spread across 20 risk groups, and no single name may exceed 4.9% of NAV.
  • Current book: 468 names, largest position 0.84% of NAV.

Agentic

Agentic workflow for factor-risk monitoring

An AI agent audits the pipeline and monitors exposures. It flags issues for the team and never produces forecasts, positions or trades.

ExecutionDraft

Execution: spread, flow and channel

How the month-end signal becomes orders, what each trade costs, and where it routes.

Month-end data

8-K filings count only if accepted before 15:30 New York time on the last trading day, leaving time to trade before the close.

Next stepsDraft

Next steps

Where the strategy goes from here.

New markets
  • CanadaTSX

    Same time zone and similar accounting data: the easiest first step.

  • EuropeSTOXX 600 exchanges

    Deep universe for a second, lowly correlated book.

  • JapanTSE Prime

    Large cross-section and governance-reform tailwinds.

Deployment for pensions
  • A market-neutral sleeve with beta ≈ 0 diversifies a pension's equity-heavy book.
  • Near-equal weights and a 230 + 230 structure keep capacity and liquidity transparent.
  • Every rule is pre-registered and auditable: a single program rebuilds the book from raw data.
For the portfolio manager
  • Agents as analysts: quote-verified 8-K events reviewed against each month's strongest picks.
  • Short-squeeze control: a crowding-aware short screen aimed at the 2024–2025 losses.
  • Stage-two alternative data plugs into the same leakage canary and placebo tests.
