The most common objection to halal investing is: "Don't you sacrifice returns by restricting your universe?" The S&P 500 Shariah Index — which applies Shariah screening to the standard S&P 500 — has been running since 2007. Here's what the data actually shows.
Performance Comparison
| Metric | S&P 500 (Conventional) | S&P 500 Shariah | Difference |
|---|---|---|---|
| 1-Year Return (2025) | +24.1% | +27.3% | +3.2% Shariah |
| 3-Year Annualized | +10.8% | +12.1% | +1.3% Shariah |
| 5-Year Annualized | +13.5% | +15.2% | +1.7% Shariah |
| 10-Year Annualized | +12.1% | +13.8% | +1.7% Shariah |
| Since Inception (2007) | +10.2% | +11.5% | +1.3% Shariah |
| Max Drawdown (2020) | -33.9% | -31.2% | +2.7% Shariah |
| Sharpe Ratio (10yr) | 0.78 | 0.85 | Better risk-adjusted |
The S&P 500 Shariah Index has outperformed the conventional S&P 500 over 1, 3, 5, 10-year, and since-inception periods. This isn't a sacrifice — it's an advantage.
Why Does the Shariah Index Outperform?
1. Tech Overweight
Shariah screening excludes banks, insurance companies, and other financial sector stocks (which make up ~13% of the conventional S&P 500). This mechanically increases the weight of technology stocks, which have been the best-performing sector over the past decade. The Shariah index is ~45% technology vs ~30% in the conventional index.
2. Low-Debt Bias
Companies with excessive debt are excluded. Research consistently shows that low-debt companies outperform high-debt companies over long periods. The Shariah screening acts as a quality filter, selecting for financially conservative companies.
3. No Financial Sector Drag
Banks and insurance companies have underperformed the broader market since 2008. Excluding them has been a net positive for the Shariah index. During the 2008 financial crisis, the Shariah index fell less because it had no exposure to the banks that caused the crisis.
When Does the Shariah Index Underperform?
The Shariah index is not always the winner. It underperforms when:
- Banks rally hard — if interest rates rise and banks profit (like late 2016), the conventional index benefits from bank exposure
- Tech corrects — the Shariah index's tech overweight amplifies tech drawdowns
- Value rotations — deep value/cyclical rotations can favor the conventional index since the Shariah index is growth-tilted
However, over full market cycles, the Shariah index's low-debt quality bias has consistently provided an edge.
Sector Comparison
| Sector | S&P 500 Weight | S&P 500 Shariah Weight | Difference |
|---|---|---|---|
| Technology | ~30% | ~45% | +15% |
| Healthcare | ~13% | ~16% | +3% |
| Consumer Discretionary | ~10% | ~12% | +2% |
| Financials | ~13% | ~1% | -12% |
| Energy | ~4% | ~5% | +1% |
| Utilities | ~3% | ~1% | -2% |
What This Means for Your Portfolio
The data is clear: halal investing does not mean sacrificing returns. In fact, the Shariah screening criteria — excluding highly leveraged companies and prohibited industries — act as a quality filter that has produced superior risk-adjusted returns.
You can replicate S&P 500 Shariah Index exposure through the SPUS ETF (SP Funds S&P 500 Sharia), which tracks this exact index.
