With an expense ratio less than 0.4?

Screening Filters

1. themes: ['Sharia', 'Islamic', 'Sharia-compliant', 'Emerging Markets']

   • Purpose: To find ETFs that are both:
     • Sharia-compliant (or marketed as Islamic)
     • Focused on Emerging Markets
   • Rationale:
     • Many databases don’t have a single “Sharia-compliant” boolean flag, so using multiple related themes (Sharia, Islamic, Sharia-compliant) increases the chance of capturing all relevant Islamic/halal products.
     • Adding Emerging Markets in the same theme filter narrows the results to funds whose mandate is to invest in emerging market equities/bonds, matching your request for EM exposure.

2. expense_ratio: { max: 0.4 }

   • Purpose: To limit results to ETFs with an expense ratio below 0.40% per year.
   • Rationale:
     • You explicitly asked for “expense ratio less than 0.4”, so this cap excludes higher-cost Sharia EM funds and keeps only relatively low-cost options.
     • This helps you compare truly cost-efficient Sharia EM ETFs rather than seeing the full range of (often more expensive) Islamic products.

Why Results Match:

• The Sharia/Islamic/Sharia-compliant themes address your requirement that the ETF must follow Islamic/Sharia principles.
• The Emerging Markets theme ensures the ETF’s investment universe is EM, not global or developed markets.
• The expense_ratio ≤ 0.4 filter directly enforces your cost constraint (“less than 0.4”).

All requested aspects (Sharia-compliant, Emerging Markets focus, and expense ratio < 0.4) are represented in the filters, so the screen is aligned with your query as closely as the data allows.
