Shariah

The 30-Second Summary

What is Shariah? A Plain English Definition

Imagine you're building a house. You wouldn't build it on a shaky foundation of sand, nor would you use toxic, flammable materials, no matter how cheap they were. You'd want solid ground, strong materials, and a design that's built to last through storms. In the world of investing, Shariah (pronounced “Sha-ree-ah”) is like a very old, time-tested architectural blueprint for building just such a portfolio. It's an ethical and moral code derived from Islamic teachings that provides a comprehensive framework for all aspects of life, including finance and commerce. When applied to investing, it's often called “Shariah-compliant investing” or “Islamic finance.” At its heart, this isn't about religious dogma; it's about a set of principles that promote fairness, social welfare, and real economic activity over pure speculation. Think of it less as a restriction and more as a quality filter. The framework is built on a few core prohibitions that have profound implications for an investor: 1. Riba (Interest): Shariah prohibits earning or paying interest. The philosophy is that money should not make money on its own; it should be used to create real-world value in the economy. This leads to a deep skepticism of debt-laden companies and conventional banks, whose business model is built on interest. 2. Gharar (Excessive Uncertainty or Ambiguity): This is the prohibition of speculative transactions where the outcome is overly uncertain or the terms are unclear. It's a direct stand against gambling and complex derivatives where one party's gain is directly tied to another's loss without creating any underlying value. It pushes investors toward businesses with clear, understandable operations. 3. Haram (Forbidden Activities): Shariah screens out companies that derive significant income from industries considered harmful or unethical. This includes alcohol, pork products, gambling, conventional financial services (due to riba), and entertainment (like pornography or nightclubs). So, a Shariah-compliant investment is simply a share in a company that has passed these ethical and financial checks. It's a business that engages in a permissible activity and does so with a strong, healthy balance_sheet that isn't dependent on the “toxic material” of excessive debt.

Why It Matters to a Value Investor

For a value investor, the principles of Shariah finance aren't foreign; they are a different dialect of the same language spoken by Benjamin Graham and Warren Buffett. The overlap is not just coincidental; it's fundamental. Here’s why this framework is so powerful from a value_investing perspective:

Essentially, applying a Shariah screen is like having a very strict, disciplined analyst working for you, automatically discarding the financially weak and the speculatively dangerous, leaving you with a smaller, more robust universe of companies to analyze further.

How to Apply It in Practice

Applying Shariah principles is a systematic, two-stage screening process. An investor can perform a basic version of this screening themselves to vet potential investments.

The Method

Imagine you're the bouncer at an exclusive club for high-quality companies. You have a two-part checklist. Step 1: The Business Activity Screen (The “What Do You Do?” Test) First, you check what the company actually does for a living. To be Shariah-compliant, a company must not derive significant income from prohibited activities. A common benchmark, used by index providers like MSCI and FTSE, is the “5% rule”: a company fails the screen if it gets more than 5% of its total revenue from any of the following:

If a company passes this first test (e.g., a software company, a healthcare provider, or a manufacturer of consumer goods), it moves to the next stage. Step 2: The Financial Ratio Screens (The “Financial Health Check-up”) Next, you examine the company's financial statements. This is where Shariah’s aversion to debt and impure income comes into play. The goal is to ensure the company's finances are sound and not reliant on interest-based mechanisms. While the exact thresholds can vary slightly between different standards bodies 2), the most widely accepted benchmarks are:

Financial Ratio Screen Rule of Thumb (Must be less than…) What It Measures
Debt-to-Total Assets 33% Tests the company's reliance on borrowed money. A low ratio indicates a strong, self-sufficient balance sheet.
Cash & Interest-Bearing Securities-to-Total Assets 33% This screen limits how much of a company's assets are held in interest-bearing accounts or securities. It ensures the company isn't acting like a bank.
Accounts Receivable-to-Total Assets 33% Checks how much of the company's assets are tied up in money owed by customers. It's a measure of liquidity and business quality.

Additionally, there's a final check on “impure” income. The total interest and other non-compliant income a company earns should not exceed 5% of its total revenue. If it does, this income must be “purified” by donating a proportional amount of the investment gains to charity.

Interpreting the Result

A company that passes both the business activity screen and all the financial ratio screens is considered “Shariah-compliant” or “Halal” for investment purposes. From a value investor's perspective, a “pass” is a strong positive signal. It suggests:

A “fail,” especially on the financial screens, is a clear red flag that would concern any value investor, regardless of their ethical framework. A company with debt exceeding 33% of its assets is taking on significant financial risk that could impair its long-term intrinsic_value.

A Practical Example

Let's compare two hypothetical companies to see the screening process in action: “Global Spirits & Foods Inc.” and “Precision Robotics Corp.”

Company Analysis Global Spirits & Foods Inc. Precision Robotics Corp.
Business Activity Produces food products, but also owns a major wine and spirits division. Designs and manufactures surgical robots for hospitals.
Step 1 Result FAIL. Revenue from alcohol is 25%, far exceeding the 5% threshold. The analysis stops here for a Shariah investor. PASS. The company's core business is in the healthcare sector, which is permissible.

Since Global Spirits failed the first test, we don't even need to look at its financials. But let's assume for a moment it was a pure food company and examine the financials of both.

Financial Health Check-up Global Spirits & Foods Inc. Precision Robotics Corp.
Debt / Total Assets 45% 15%
Cash & Int. Bearing Sec. / Total Assets 10% 20%
Accounts Receivable / Total Assets 20% 25%
Step 2 Result FAIL. Its debt-to-assets ratio of 45% is well above the 33% limit. This indicates high leverage and financial risk. PASS. All of its financial ratios are well within the acceptable 33% limits.

Conclusion: Precision Robotics Corp. would be considered a Shariah-compliant investment. A value investor would also be far more attracted to Precision Robotics. Its permissible business is complemented by a rock-solid balance sheet, making it a much safer long-term investment compared to the highly leveraged Global Spirits, even if we ignored the alcohol business. This example shows how the Shariah screen naturally guides you toward the type of financially conservative companies that value investors seek.
