Portfolio Construction · Small-Cap Value · Three-Statement Quality
A second book within the satellites, built on the small-cap value premium — screened for halal compliance, filtered through a strict balance-sheet rule (debt/equity below 30%), and assessed with deep three-statement analysis across the balance sheet, income statement, and cash flow statement. Validated, as always, with the Fama-French five-factor model.
The Rationale
The original 20-stock book of the sleeve is a large-cap quality book. Its Fama-French regression showed a strong positive RMW (profitability) loading of +0.33, a negative SMB (it tilts large, not small), and a slightly negative HML (it leans growth, not value). That portfolio deliberately gives up the size and value premia in exchange for a concentrated quality and profitability tilt.
This second portfolio is designed to be its complement. Where the first book is large-cap and quality-focused, this one targets the two factors the first one gives up: the size premium (SMB) and the value premium (HML). Both are well-documented in the Fama-French literature — the CFA curriculum notes that Fama and French formally outlined value investing by proposing the book-to-market ratio, and that small-cap companies tend to be less mature with potentially greater room for future growth and a lower degree of analyst and public scrutiny. That lower scrutiny is precisely where a disciplined bottom-up investor can find mispricing.
But small-cap value is also where the most value traps live — cheap companies that are cheap for good reason. The CFA curriculum is explicit that the value premium may exist partly to compensate investors for the greater likelihood that these companies will experience financial distress. That is exactly why this portfolio inverts the previous screening emphasis. Instead of leading with cash-flow quality, it leads with balance-sheet strength — a strict debt/equity ceiling of 30% — and then requires all three financial statements to confirm quality. In small-cap value, a fortress balance sheet is the single most effective defence against the value trap.
Selection Criteria
Applied in strict sequence. A company that fails any filter is excluded before the next is considered. The balance-sheet rule is the defining feature of this portfolio.
Filter 01
No gambling, alcohol, weapons, tobacco, or conventional financial institutions. Applied at the business-model level. This is why the otherwise-rich small-cap banking universe is entirely excluded.
Qualitative · pass/failFilter 02
Non-compliant income below 5% of revenue; interest-bearing debt below 33% of market cap (DJIM/AAOIFI). Note: our balance-sheet rule below is far stricter than the halal debt ceiling.
Debt < 33% mkt capFilter 03 · DEFINING RULE
The hard rule. Total debt divided by shareholders' equity must be below 30%. This single filter eliminates most of the small-cap universe and is the primary defence against the value trap and financial-distress risk.
D/E < 0.30 — hard ceilingFilter 04
Positive and growing net income; durable gross and operating margins; revenue quality (recurring preferred); no persistent divergence between reported earnings and operating cash flow.
Profitable + margin stabilityFilter 05
Positive operating cash flow that converts cleanly from earnings. Low accruals (the Sloan earnings-quality factor). Free cash flow generation, not just reported profit.
CFO > 0 · low accrualsFilter 06
Reasonable valuation relative to book, earnings, or cash flow — the HML (high book-to-market) tilt. Not deep value at any cost; value with quality, to avoid the trap.
Reasonable P/B · P/E · P/FCFFilter 07
Regression confirms the intended tilts: positive SMB (small), positive HML (value), with quality factors (RMW, CMA) confirming the balance-sheet discipline shows up in the return history.
SMB+ · HML+ · RMW≥0The Analytical Framework
Each financial statement answers a different question about the durability of a business. Reading all three together — and reconciling them against each other — is the core of the bottom-up process, structured around the financial-statement analysis framework in the CFA curriculum.
For small-cap value, the balance sheet is the first and most important lens because the value premium is partly compensation for distress risk. A company that is cheap and financially fragile is a value trap waiting to spring. The defining rule of this portfolio — debt/equity below 30% — lives here. A low-leverage small cap can survive a recession, refinance on its own terms, and use a downturn to take share from over-levered competitors.
The income statement tests whether the company makes real money and whether those profits are durable. For value names, the danger is declining profitability masked by a cheap headline multiple. The focus is on margin stability and trend, not just level — a company with stable or expanding gross margins has pricing power; one with eroding margins is often a structurally challenged business that looks cheap because it deserves to be.
Cash flow is the lie detector. The CFA curriculum highlights Sloan's seminal earnings-quality research — the finding that the market fails to fully distinguish the accrual and cash-flow components of earnings, and that high-accrual (low cash-conversion) earnings are lower quality and tend to reverse. If a company reports strong earnings but weak operating cash flow, the earnings are suspect. This statement confirms or refutes the income statement.

The debt-free core
The three strongest balance-sheet names are entirely debt-free with net cash positions and ROEs near or above 28%. Powell Industries (electrical equipment for data centres and energy) and Exponent (asset-light engineering consulting) are textbook examples of low-leverage compounders trading at value multiples. These form the high-conviction core of the sleeve.
Why the bank universe is empty
Most small-cap value screens are dominated by community banks and regional financials — they are perennially cheap on book value. Every one is excluded here by the halal lending screen. This is the single largest difference between this portfolio and a conventional small-cap value index, and it removes a major source of the value factor's historical return.
Borderline cases — flagged, not hidden
UFP Technologies sits at a debt/equity of 0.29 — inside the 30% ceiling, but only just, and after recent acquisition activity. It is included with that flag visible. AAON, a quality HVAC name, was excluded precisely because its D/E rose to 0.42–0.88 after acquisitions. The rule is applied consistently, even when it costs a good business.
Worked Examples
The bottom-up process applied in full to the three highest-conviction names — reading each through the balance sheet, income statement, and cash flow lens.
Balance Sheet
Entirely debt-free with roughly $389M in cash and short-term investments against zero debt. Short-term assets ($810M) exceed both short-term ($405M) and long-term ($19M) liabilities by a wide margin. This is the strongest possible balance sheet — it passes the 30% rule with a 0% reading.
Income Statement
ROE of ~29.5% and operating margin around 22%, both exceptional for an electrical-equipment manufacturer. Revenue has grown strongly on data-centre and LNG infrastructure demand. Operating profit grew ~22% year-over-year. Margins have expanded, not contracted — the mark of genuine pricing power rather than a cheap-for-a-reason value trap.
Cash Flow
The net cash position confirms strong cash generation — a company cannot accumulate $389M in net cash without converting earnings to cash efficiently. Capital-light relative to its order book. The combination of debt-free balance sheet, high ROE, and strong cash generation at a reasonable multiple is the ideal small-cap-value-with-quality profile.
Balance Sheet
A fortress balance sheet — roughly $100M in cash and zero debt. For a company of NAPCO's size this is an enormous cushion, giving it the flexibility to invest through cycles and weather any downturn in equipment sales. Passes the 30% rule at 0%.
Income Statement
The story here is the mix shift: recurring SaaS revenue from StarLink cellular radios has grown at a ~34% CAGR since 2019 and now represents nearly 80% of gross profits. Net margin of ~25% and ROE of ~28%. The shift from one-time hardware to recurring subscription revenue is exactly the revenue-quality improvement the income-statement screen rewards — though recent equipment-sales softness is a near-term watch item.
Cash Flow
Simply Wall St flags NAPCO's earnings as high quality — meaning reported earnings are backed by cash, with low accruals (the Sloan test passes). The recurring-revenue base produces predictable, high-margin operating cash flow. The combination of zero debt and high-quality recurring cash flow makes this a low-distress-risk value-and-growth name.
Balance Sheet
Debt-free, asset-light professional-services model. Exponent's balance sheet carries minimal fixed assets — its value is in its PhD-level scientific staff, not capital equipment. This means it passes the 30% rule trivially and requires very little reinvestment to grow. The downside is that book value is low, so it scores less on a pure price-to-book value screen — its value characteristic comes from cash-flow and earnings multiples instead.
Income Statement
EBITDA margins around 24% with a diversified revenue base across failure analysis, regulatory consulting, and litigation support. The business is counter-cyclically resilient — dispute and failure-analysis work often increases during economic stress, providing a natural hedge. Revenue is project-based but recurring at the client-relationship level.
Cash Flow
Asset-light consulting converts earnings to cash extremely efficiently — minimal capex, low working-capital needs. Exponent has a long record of returning cash through dividends and buybacks rather than accumulating it unproductively or making dilutive acquisitions. High, clean cash conversion is the hallmark of the model.
Factor Validation · Actual Regression
Run on the final 12 equal-weighted holdings over 83 monthly observations (Jan 2019 – Dec 2025), using the Kenneth French factor series. The regression confirms the size tilt cleanly — and is honest about where the value and quality tilts fell short.
The complementarity thesis — partly confirmed
The original 20-stock portfolio loads negative SMB (large-cap), negative HML (growth), and strongly positive RMW (+0.33 profitability). This book was built to be its mirror. The regression confirms the most important half of that thesis: SMB came in at +0.43 (t = 2.50) — a real, significant small-cap tilt that the large-cap book lacks. The value tilt is present but weak (HML +0.17, not significant), the predicted cost of excluding the banking sector where value lives. And the profitability tilt did not materialise at the portfolio level (RMW +0.05) — a low debt/equity balance sheet, it turns out, does not guarantee a positive RMW loading. The honest read: this book genuinely diversifies the sleeve on size, but it is more a small-cap book than a clean small-cap-value book, and should not be counted on to add profitability exposure.
What to Verify Before Acting
This is a candidate list, not a finished portfolio. Every name here must have its current debt/equity ratio, halal compliance, and three-statement quality re-verified against the latest filings before any allocation. Small-cap financials change faster than large-cap ones, and a debt-funded acquisition can push a name over the 30% ceiling between filings — exactly what happened to AAON, which is why it was excluded.
The Canadian names need SEDAR+ verification. Celestica and Calian are included as candidates but their debt/equity ratios must be confirmed from Canadian filings, and their halal compliance verified — Celestica in particular serves diverse end markets that need segment-level review.
Small-cap value carries real risks the large-cap book does not. Lower liquidity, wider bid-ask spreads, higher volatility, and greater sensitivity to economic cycles. The size premium is real but it is not free — it compensates for exactly these risks. Position sizing should be smaller per name than in the large-cap sleeve, and the whole small-cap value book should be a minority of the total sleeve allocation.
The halal screen meaningfully reduces the value-factor opportunity set. By excluding all banks and financials — which dominate conventional small-cap value indices — this portfolio gives up a large portion of where the value premium has historically lived. The names that remain are higher quality on average, but the sleeve will not behave like a standard small-cap value index. That is a deliberate trade-off, consistent with the mandate.
