Investment Philosophy
Good portfolio construction is not just about picking stocks. It is about building a coherent architecture — one where every layer has a defined role, every security is selected with purpose, and the overall structure reflects both your values and your understanding of how markets actually work. This is mine.
The Foundation
Most investors start with stocks. They hear about a company, read an article, notice a product they use every day, and decide to invest. That is not a strategy — it is pattern-matching dressed as analysis. A genuine investment framework starts one layer above the individual security and asks a harder question: what structure should a portfolio have, and why?
My answer to that question is a core-plus-satellite structure — certified halal ETFs at the core, individual stocks I research and cover as the satellites — combined with a disciplined halal screening process and a research practice that draws on whatever lens the question demands — thematic, company-specific, or simply curiosity-led. Each of these elements is independently important. Together, they form an investment process that is systematic enough to be repeatable, principled enough to reflect my values, and rigorous enough to withstand scrutiny.
The framework is not a black box. Every decision has a rationale, every screen has a clear definition, and every stock in the satellite layer has been assessed against the same quality criteria — regardless of how it first crossed my desk. The goal is to build something that makes sense in writing — because if you cannot explain exactly why a company belongs in your portfolio, it probably does not belong there.
"Investing is not merely a financial act. For a Muslim investor, every security in a portfolio is also a moral endorsement — a share in how a company earns its money, treats its stakeholders, and engages with the world. The ethical mandate is not a constraint on returns. It is the first principle from which everything else follows."
— Hisham Ahmed, Investment Philosophy NotesThe Architecture
A well-constructed portfolio has layers that do different things. Conflating them — expecting one stock to provide both broad diversification and targeted alpha — leads to a portfolio that does neither well.
Before any financial analysis begins, every individual stock I consider for the satellite layer passes four exclusion screens: no gambling, no alcohol, no war or weapons, no banks or companies earning revenue from lending or interest. These are not preferences — they are non-negotiable conditions. A company that fails any one of them is excluded, regardless of its financial quality, its growth prospects, or how attractively it is priced. The screening layer also applies a quantitative halal check: interest-bearing debt below 33% of market capitalisation, and non-compliant income below 5% of total revenue. Both the qualitative and quantitative screens must be satisfied. The core ETFs are not exempt from this principle — they simply satisfy it differently: each is a certified Shariah-compliant fund whose provider already applies an equivalent exclusion-and-ratio screen to every holding. The ethical foundation therefore governs the whole portfolio; I apply it directly to the stocks I pick and rely on the funds' own certification for the core.
Once the ethical foundation is established, the core layer provides broad, low-cost exposure to the Shariah-screened investment universe. This is not where active judgment is applied — it is where the portfolio captures systematic market returns efficiently. Certified halal ETFs available to Canadian investors — the S&P 500 Shariah, FTSE USA Shariah, and Dow Jones Islamic families chief among them — fill this role. Because each fund is already Shariah-certified, the core inherits the ethical screen by construction. They diversify across hundreds of screened securities, rebalance automatically, and cost a fraction of active management. The core is typically 65–70% of the total portfolio. Its job is to ensure that even if the satellites underperform, the portfolio still earns broad market-level returns. It is the portfolio's insurance policy against the limits of individual stock selection.
The satellite layer is the individual stocks I cover — and where my own analytical work does its most important job. These names are not randomly selected halal-screened stocks. Ideas reach the satellites from several directions: a structural theme I am following, a company someone has asked me to look into, something I stumble on while reading, or plain curiosity. Wherever an idea originates, it earns its place the same way — by passing every ethical screen and then satisfying the quality bar: high operating cash flow with a verifiable track record of organic growth. The aim is to tilt the portfolio toward the profitability factor (RMW in the Fama-French five-factor model) more deliberately than a broad ETF can, because the ETF dilutes the factor across hundreds of names while the satellites concentrate it in the highest-conviction compounders. This is the portfolio's alpha engine, at 30–35% of total capital.
Portfolio Structure
Each component has a specific function. The core provides stability and beta. The satellites provide the quality tilt and potential outperformance. Neither can do the other's job effectively.
Core principle
The core captures market returns at minimal cost. Even if the satellites underperform, you still own the broad Shariah market return. The core is the portfolio's floor, not its ceiling.
Satellite principle
Satellites are not diversification vehicles — the core handles that. Each position must earn a specific thesis: a quality screen it passes, a factor tilt it reinforces, a CFO growth record it can verify. How the idea arrived does not exempt it from the bar.
Interaction principle
The two layers work together: the core provides the breadth the satellites give up through concentration; the satellites provide the quality tilt the ETF dilutes through breadth. Neither alone achieves what both together do.
How Ideas Enter the Satellite Layer
Good ideas arrive from wherever they please — a structural theme I have been following for years, a company a friend or reader asks me to look into, a name that surfaces while I am researching something else entirely, or simple curiosity about a business I keep encountering. The origin of an idea says nothing about its quality. What matters is what happens after it arrives.
So the question is not "top-down or bottom-up?" — both are lenses, and I use whichever the question demands. A thematic lens is how I noticed that ageing demographics and surgical robotics converge on one company; bottom-up analysis is how I then confirmed whether that company actually deserved capital. The theme opened the door. The filings decided whether the name stayed in the room. Every idea, regardless of how it entered, must clear the same bar: pass every ethical screen, demonstrate verifiable organic cash-flow growth, and survive the factor check. That discipline is non-negotiable. The route in is not.
The thematic / discovery lens — where ideas originate
The bottom-up lens — where ideas are validated
The two lenses are sequential, not rival. The first finds candidates; the second decides which deserve capital. A theme that never survives the filings is just a story — and a filing read in isolation, with no sense of the forces moving the business, can be just as blind. Used together, they are far stronger than either on its own.
The Process
This is the exact sequence applied to every idea that reaches the satellite layer — whatever door it came in through. No step is optional. A company that fails any step does not proceed to the next.
Qualitative Exclusion Screen
Every candidate is assessed against the four non-negotiable exclusions: gambling, alcohol, war and weapons, banking and lending. The check is applied at the business-model level — is this a primary activity? — not at the revenue-threshold level. A company whose core business fails any screen is rejected immediately, without proceeding to financial analysis.
Where most screens fail: The lending exclusion requires reading segment disclosures, not just sector classification. Shopify is classified as "technology" — but Shopify Capital lends money to merchants. Loblaw is classified as "consumer staples" — but PC Financial is a licensed lender. Sector codes do not catch these. The filing does.
Quantitative Halal Screen
Interest-bearing debt must be below 33% of trailing 24-month average market capitalisation (DJIM/AAOIFI standard). Non-compliant income — interest on cash, any prohibited activity income — must be below 5% of total revenue. These are verified from the company's most recent annual report, not from a third-party screener whose methodology may differ.
Cash Flow Quality Assessment
The Statement of Cash Flows from the SEC EDGAR filing (or SEDAR+ for Canadian companies) is pulled directly. Five years of annual operating cash flow (CFO) data are extracted and a CAGR is computed. This is the primary quality filter. A company with a CFO CAGR below 5% fails — not because it is a bad business, but because it does not satisfy the mandate's quality criterion.
Balance Sheet & Income Statement Quality
Two additional statement-level checks are applied before proceeding. The balance sheet is assessed for financial strength and capital discipline — low leverage, strong interest coverage, no material off-balance-sheet exposure. The income statement is assessed for revenue quality and margin durability — recurring or subscription revenue is preferred over transactional, and persistent divergence between reported earnings and operating cash flow is a disqualifying flag.
The earnings-vs-CFO divergence test: If a company consistently reports strong earnings but weak operating cash flow, something is wrong with the quality of those earnings — channel stuffing, aggressive revenue recognition, or non-cash charges masking real deterioration. CFO is harder to manipulate than earnings. It is the more honest measure.
Competitive Position Assessment
A company with a strong historical CFO track record is not automatically a strong future compounder. The business must have a structural reason to maintain its margins and market position — a switching-cost moat (Cintas), a network effect (Visa/Mastercard), a cost advantage (Dollarama/Grainger), or a unique asset (Franco-Nevada's royalty streams, Stryker's Mako installed base). This assessment is qualitative, not quantitative — but it is applied consistently and documented in the investment thesis before a position is taken.
Fama-French Factor Validation
The Fama-French five-factor model is used as a validation tool — not a stock picker. Each candidate's monthly returns are regressed on the five factors (Market, SMB, HML, RMW, CMA) using the Kenneth French Data Library factor series. The RMW (Robust Minus Weak) loading is the primary check: a significantly positive loading confirms that the stock's return history is consistent with the profitability factor that the satellite layer is designed to harvest. A negative or near-zero RMW loading on a candidate that passed the previous screens is a flag that warrants further investigation.
What this step cannot do: Factor regression is backward-looking. A positive past RMW loading does not guarantee future profitability — it confirms the stock's historical returns were consistent with the thesis. It is a validation tool, not a prediction. It is most useful for rejecting candidates that claim to be quality compounders but whose return history says otherwise.
Portfolio Construction & Weight Discipline
A security that passes all six previous steps is not automatically added at an arbitrary weight. Each satellite position is sized relative to its conviction level, its correlation with the ETF core, and the overall factor tilts of the portfolio. Names that provide genuine diversification from the ETF core (different geography, different sector, lower tech correlation) receive modestly higher weights. Names that heavily overlap with the ETF core receive lower weights to avoid doubling up on the same exposure. The portfolio RMW loading is checked after each addition — the goal is to maintain a loading above +0.25.
How It All Connects
Each piece of published research on this site is a direct application of one or more layers of this framework. The philosophy is not theoretical — it is worked through in public.
Ethical foundation + balance-sheet screen
A worked example of the screens in practice — halal exclusions applied at the business-model level, a strict debt/equity < 30% balance-sheet rule, and deep three-statement quality analysis on twelve names.

Read →What This Framework Cannot Do
A systematic framework eliminates many errors — emotional decisions, sector fads, headline-driven trading, and the slow drift of a portfolio away from its stated mandate. It does not eliminate all errors, and it is important to be precise about what it cannot guarantee.
The CFO growth screen is backward-looking. A company with a ten-year track record of 15% annual CFO growth has demonstrated quality — but it has not guaranteed the next ten years. Business models change, competition intensifies, and secular tailwinds fade. The screen selects the strongest historical compounders; it cannot predict which ones will continue.
The factor regression is also backward-looking. An RMW loading of +0.33 on the portfolio over 83 historical months confirms that the portfolio's return history was consistent with a profitability tilt. It does not guarantee that the same factor loading will persist, or that the profitability premium will continue to be positive in future periods.
The halal screen captures what is visible in filings. A company that begins a lending programme after its most recent annual report would pass the screen until the next filing is reviewed. The screen is as current as the last time the filings were read — which is why quarterly review is not optional.
The satellites may not outperform the core. The entire rationale for holding 30–35% in individual stocks rather than adding to the ETF core is the thesis that quality stock selection with a strong CFO mandate and profitability factor tilt will generate incremental return above the ETF. That is a thesis, tested by the regression, supported by academic evidence, but not guaranteed. If three years of live tracking show the satellites consistently underperforming the core, the honest response is to reduce the satellite allocation — not to rationalise continued underperformance.
