Constraint checks

How this book measures against the concentration and liquidity rules — as implemented here

How this book was built

These are UNCONSTRAINED factor sleeves: the construction pipeline sorts on a signal and cap-weights the top bucket, applying no issuer cap, no industry cap and no liquidity screen beyond the universe filter. A failing test therefore reports a constraint that was never applied during construction — it is not a defect in the strategy and not an error in the data. The same signal can be solved subject to these constraints.

7 independent checks plus 1 arithmetically implied by another check (RIC / IRC 851(b)(3)(A) 50% bucket), which is reported separately so the tally cannot overstate scrutiny.

1 of 7 checks could not be tested. Those are neither passes nor failures — they are gaps in what the data can answer, and they are excluded from the passed count above rather than folded into it.

Engineering approximation of the cited rules for a DRAFT / HYPOTHETICAL model portfolio that is not a registered fund. This reports whether the portfolio passes the stated test AS IMPLEMENTED HERE; it is not a compliance opinion and is not a statement that any fund is compliant. Real filings need securities counsel.

No verdict sits within 1.0pp of its limit.

Data version — panel=20260719T025334 rows=2239262 asof=202607 issuers=20260719T014536 rates=20260804T224700

Measured on the 2026-07 formation date across 111 holdings (cap-weighted). A different formation date can produce different verdicts.

Derivatives risk (Rule 18f-4)

Whether this long-only book is subject to the VaR tests at all

This assessment describes the long-only book this fund holds — the top bucket only.

Governing rule
Rule 18f-4(c)(4) limited derivatives user exception

This fund QUALIFIES for the limited-derivatives-user exception, so it is excepted from the VaR tests; the ratio below is informational, not the operative limit.

Limited derivatives user exceptionby construction

Rule 18f-4(c)(4): a fund whose derivatives exposure (gross notional, including the value of assets sold short) is <= 10% of net assets is excepted from the VaR tests and the full derivatives risk management program.

Qualifies
Required
<= 10% of net assets
Exposure
0% of net assets
Margin
+10pp

No confidence interval: this follows from portfolio construction, not from an estimate.

Rule 18f-4(c)(2)(i): fund VaR at 99% over 20 trading days must not exceed 200% of the designated reference portfolio's VaR on the same basis.

Informational — does not govern

This fund is excepted from the VaR tests, so the ratio below is context rather than the operative limit. It is shown because it is still a description of the book’s risk, not because it decides anything.

The research long-short construction behind this factor does not qualify for this exception — a dollar-neutral book counts its full short notional, which is 100% of net assets against a 10% threshold. This product sidesteps that by holding the long leg alone, which is also why the long-leg Sharpe is reported separately throughout the site.

Since publication

Did the edge survive the paper coming out?

published 1981
Entirely since publication
All 331 months of our record post-date the 1981 paper.
Sharpe 0.142.0% p.a.January 1999July 2026

There is no “before” to compare against — the predictor was already public when our data begins, so every month shown is out-of-sample relative to the original study.

Split at January of the year after the factor was published. The post-publication stretch IS genuinely out-of-sample relative to the original study -- the predictor was public by then -- so it speaks to whether the effect survived being known. Nothing is fitted here, so this is performance SINCE PUBLICATION, not validation of a model. Note the 'pre' side is our data before publication (our panel starts ~1999), NOT the study's original in-sample period, which usually ran decades earlier; a decay figure compares before-vs-after within our sample and is not a comparison against the published result.

3-year rolling windows, stepping 1 year (26 windows). Dispersion is the spread of window Sharpes — higher means the record depends more on which era you look at.

Rules-based factors fit no parameters, so these windows are not out-of-sample tests and do not validate a fitted model. They show whether the factor's record is consistent across eras or driven by one regime.

Long leg = the top bucket this fund holds; long-short additionally shorts the bottom bucket and is not achievable in a long-only vehicle. Trailing figures run through July 2026: 1 year is a plain cumulative 12-month return (cum.), 3 years and longer are annualised (p.a.). Years marked with a month count are partial. These match the fact sheet’s tables by construction. Hypothetical backtest, gross of the placeholder expense ratio and trading costs — not investor results.

Methodology

The Foundry Financial Services Small Size Factor ETF tracks a rules-based model that ranks Financial Services common stocks each month by a Small Size signal and holds the top quintile with the lowest values. Signals are computed from point-in-time Sharadar fundamentals and total-return prices. The portfolio reconstitutes monthly and is cap-weighted within the long leg.

This is a hypothetical model portfolio for research display only — not a registered fund, not an offer, and not investment advice.
