The Principled Portfolio Framework: The Full Picture

Eight issues in. You now have the full diagnosis.

You know that a Shariah screen doesn’t produce a filtered market — it produces a structurally different one, with its own sector weights, its own geographic concentrations, and its own behaviour across market cycles.

You know how the screening rules work and what happens when they change. You know why the debt screen provides real crisis protection. You know the bond gap is real and that no single instrument fills it cleanly. You know that Islamic capital is concentrated in specific places — the GCC, Malaysia, the US — and almost entirely absent from others. You know what each instrument actually does, and that compliance is the starting point, not the ending point. 

Now we put it all together. 

The Principled Portfolio Framework — or PPF — is MizanMacro’s systematic approach to building and governing a Shariah-aligned portfolio. It has three layers: Foundation, Construction, and Stewardship. Each one does a distinct job. Together, they turn a collection of halal investments into a portfolio that has been deliberately designed, clearly understood, and properly maintained over time. 

This issue walks through all three layers. And then applies them to a single hypothetical portfolio — from blank page to finished structure — so you can see exactly how it works in practice.

The Three Layers at a Glance 

The PPF is not complicated. Three questions. Three answers. Each one building on the last. 

Foundation comes first because you can’t build well on a foundation you haven’t examined. Construction comes second because knowing your universe is not the same as knowing how to use it. Stewardship comes third because a portfolio is not a snapshot — it’s a living system that needs to be maintained. 

Let’s go through each one.

Layer 1: Foundation — Know Your Universe 

The Foundation layer is about getting honest answers to one question before you touch the allocation: what is my investable universe, really? 

Not “what’s halal in general.” Specifically: which companies, which funds, which instruments, in which geographies, screened by which methodology, at what thresholds — are actually available to you right now? 

This sounds obvious. It almost never gets done properly. 

Most investors choose a halal ETF because it was the first one that appeared in a search, or because someone recommended it, or because it was the easiest to buy on their platform. They don’t know which screening methodology it uses, whether that methodology uses market-cap or total-assets as its denominator, or what the actual sector composition looks like. 

The Foundation layer requires you to find out.

Three Foundation Questions 

1. Which screening standard are you following — and do you know what it actually contains? 

SPUS uses S&P’s methodology with a market-cap denominator. HLAL uses FTSE’s methodology with a total-assets denominator. These are not the same. Since DJIM dropped two of its three financial tests in September 2023, the universe each standard produces has shifted. If you don’t know which one you’re following, you don’t know what you own. 

2. What does your universe actually look like, sector by sector and geography by geography? 

Your Shariah-compliant equity universe is roughly 55% technology (in the US portion), has almost no financial companies, has a quality tilt toward low-debt businesses, and is concentrated in the US, GCC, and Malaysia. That’s not a neutral representation of the global economy. It’s a specific, structured set of exposures with identifiable concentrations and identifiable gaps. Mapping it before you allocate means you make deliberate decisions instead of accidental ones. 

3. Are the instruments you’re considering compliant — or just assumed to be? 

Not every product marketed as “Islamic” or “halal” has the same rigour behind it. Some ETFs have strong, regularly audited Shariah boards. Others have lighter oversight. Some sukuk structures are universally accepted; others are contested. The Foundation layer requires you to check, not assume. 

Layer 2: Construction — Build Deliberately 

The Construction layer takes your mapped universe and turns it into a deliberate portfolio structure. 

Deliberate is the key word here. Most Shariah-aligned portfolios aren’t built — they’re accumulated. An ETF here, a sukuk fund there, some commodity murabaha because it was easy to set up. The result is a collection of compliant instruments without any coherent logic connecting them. 

Construction thinking is different. It asks three questions at the portfolio level, not the instrument level. 

What factors does this portfolio have — and are they intentional? 

As Issue 8 showed, Shariah-compliant portfolios automatically carry three factor exposures: low leverage (from the debt screen), a quality tilt (from what’s left when high-debt companies are removed), and specific sector exclusions (almost no financials, very little consumer staples, heavy technology). These factors are why Islamic portfolios outperformed in 2008 and 2020. 

But “automatically” is not the same as “deliberately.” If you don’t know you have a quality tilt, you can’t maintain it intentionally. You can’t check whether it’s drifting. You can’t explain why your portfolio behaved the way it did. 

Construction makes these factors explicit. You name them, you measure them, and you decide whether to lean into them or moderate them. 

How does each instrument fit into the whole? 

The wrong question is: “Is this a good ETF?” The right question is: “How does this fit into the portfolio I’m building?” 

A Malaysian sukuk fund might be excellent on its own. But if your portfolio already has heavy ASEAN equity exposure, adding it increases concentration rather than reducing it. The instrument isn’t the unit of analysis. The portfolio is. 

What is the portfolio designed to do when conditions change? 

A constructed portfolio has thought about what happens if tech corrects by 30%. Or if oil falls sharply and drags both GCC equities and GCC sukuk down at the same time. Or if a specific holding drifts out of compliance. 

Screening alone doesn’t do this thinking. Construction does. 

Layer 3: Stewardship — Maintain What You Built 

Construction is a snapshot. Stewardship is the system that keeps it working over time. 

Markets move. Companies drift in and out of compliance. Your own life changes — your income, your time horizon, your need for liquidity. A portfolio that was well-constructed on day one can become poorly positioned over years of neglect. 

Stewardship is the set of habits and rules that prevent this from happening. It has four components. 

None of these tasks is complicated. What makes them effective is doing them consistently — on a schedule, with a system, rather than reactively when something has already gone wrong.

Why Stewardship Is Different for Shariah-Aligned Portfolios 

Conventional investors have to think about rebalancing and drift too. But Shariah-aligned investors have two additional maintenance tasks that conventional portfolio management simply doesn’t have. 

The first is compliance monitoring. A conventional investor who holds a company doesn’t need to check whether it’s still “eligible” for their portfolio. A Shariah-aligned investor does. Companies can drift in and out of compliance as their financials change. An ETF that uses market-cap-based screening may automatically remove holdings during a market downturn — which is itself a form of compliance drift you need to understand and track. 

The second is purification accounting. Most Shariah-compliant funds hold companies that earn a small portion of their income from impermissible sources — up to the permitted threshold. As an investor, you are responsible for donating that proportion of any income you receive to charity. This is a small amount in most cases, but it’s your obligation, and it needs to be tracked. 

These two tasks have no equivalent in conventional portfolio management. They’re specific to the architecture of Shariah-aligned investing, and they’re why Stewardship is a distinct layer of the PPF rather than just “maintenance.” 

The PPF in Practice: A Complete Portfolio Walkthrough 

Theory is useful. A concrete example is better. Let’s walk through the three PPF layers applied to a hypothetical investor building a Shariah-aligned portfolio from scratch. 

The investor: Amir. 34 years old, based in London. Works in technology. Has £50,000 to invest with a 15–20 year time horizon. Comfortable with moderate-to-high equity exposure. Wants Shariah compliance throughout.

Step 1: Foundation 

Amir starts by mapping his universe. 

He chooses SPUS as his primary US equity ETF and reads the fund fact sheet. He learns it uses S&P’s methodology with a market-cap denominator, carries roughly 55% technology, and has essentially zero financial company exposure. He notes the denominator issue: in a sharp market downturn, some holdings could get automatically removed as their market-cap-to-debt ratios shift. 

He looks at his non-equity options. WSHR gives him international halal equity exposure outside the US. There are several GCC-and-Malaysia sukuk funds available through his broker. He can access a commodity murabaha fund for liquidity. A Malaysia-focused equity fund is available but requires a higher minimum — he notes it for later. 

He maps the sector exposure: heavy US technology (SPUS), manufacturing and trade-linked economies (WSHR), oil and real-asset-backed income (GCC sukuk), export-driven and more diversified income (Malaysian sukuk). 

One thing Amir notices at the Foundation stage: he works in tech. His salary, his career prospects, and — if he follows the default path — his portfolio are all going to move together. That’s not diversification. He decides to moderate his US tech exposure slightly. 

Foundation output: Amir now has a clear picture of what’s available, what each instrument contains, and one specific concentration risk to address. He hasn’t allocated anything yet. He’s ready to construct.

Step 2: Construction 

Amir builds his allocation deliberately. Here is what he arrives at, and why. 

Walk through the logic: 

SPUS at 45% (not 60–70%, which is what a default allocation might look like) because Amir’s career is already heavily tied to the US tech sector. He wants equity growth from SPUS, but he’s deliberately pulled back from the default concentration. 

WSHR at 15% brings in international exposure — European, Asian, and emerging market companies that aren’t driven by the same forces as US technology. This also partially addresses the geographic concentration issue from Issue 5. 

The sukuk fund at 20% is the income and stability sleeve. Amir has chosen a fund that holds both GCC and Malaysian sukuk — because GCC sukuk alone would be too tied to oil prices, as Issue 4 and Issue 5 both explained. 

The Malaysian equity fund at 10% is deliberate geographic diversification within equities. Malaysian Shariah equities are tied to different economic forces than US tech or Gulf oil. They introduce genuine diversification into the growth sleeve. 

Commodity murabaha at 10% is the liquidity buffer. Amir isn’t treating this as an investment — he knows it’s effectively cash earning a small return. He keeps it at 10% because he wants the flexibility to deploy it over the next 12–18 months as he refines the portfolio. 

Construction output: A deliberate portfolio where every position has a purpose. Amir knows what each allocation is doing, why it’s sized the way it is, and what factors the overall portfolio has. Nothing is there by accident.

Step 3: Stewardship 

Amir sets up his maintenance system before he invests a single pound. He decides on three rules. 

First, he will review the portfolio allocation every quarter. If any allocation has drifted more than 5% from its target, he will rebalance — by adding new money proportionally, not necessarily by selling. 

Second, after any market move of more than 15%, he will check whether any of his ETF holdings have drifted out of compliance due to the market-cap denominator issue. This is particularly relevant for SPUS. 

Third, at the end of each tax year, he will calculate his purification obligation from the dividend income received and donate that amount to charity. His ETF fund fact sheets publish the required purification ratios. 

Stewardship output: A set of rules that keeps the portfolio working the way Amir intended — not just on day one, but over the 15–20 years he plans to hold it. 

What Makes This Different From Just Buying Halal ETFs 

A fair question at this point: is all of this necessary? Can’t you just buy SPUS and a sukuk fund and leave it alone? 

You can. Many investors do. And they will get broadly decent results, because the Shariah screening process automatically builds in some structural advantages — the low leverage, the quality tilt, the sector exclusions. 

But “automatic” is not “deliberate.” And the difference between automatic and deliberate shows up in three specific places. 

It shows up when tech corrects by 30% and you have 70% of your portfolio in SPUS because no one told you about the concentration risk. 

It shows up when GCC sukuk and GCC equities fall together during an oil shock and you realise your “balanced” portfolio was actually a single concentrated bet on the Gulf economy. 

It shows up when a company in your fund drifts out of compliance and you don’t notice for two years because you had no monitoring system in place. 

The PPF doesn’t protect against all losses. No framework does. What it does is make sure that when your portfolio behaves a certain way, you understand why — and that the behaviour is the result of deliberate choices, not accidental ones. 

Where We Are in the Series 

Eight issues built the structural diagnosis. This issue brought it together into a framework. 

The remaining issues in this series build on the PPF in two directions. Issue 10 goes deeper into a specific Stewardship challenge: the cash drag problem — why Islamic portfolios structurally hold more cash than they should, how that drag accumulates, and what to do about it. Issue 11 zooms out to the macro picture: why the modern financial system is built on debt, what that means for systemic fragility, and why Islamic finance’s structural refusal to participate in interest-based capital formation is more than a religious position. 

The framework is complete. Now we go deeper.

Foundation. Construction. Stewardship. The architecture is different. The framework is built for it.
