The document discusses Islamic asset allocation and whether Islamic investment methodology provides superior risk diversification compared to conventional investing. It notes that Islamic investing excludes interest-based businesses and companies with substantial non-compliant income. This limits the investment universe but may result in more stable portfolio values with less systemic risk due to prohibitions on excessive leverage. Overall, the document examines how modern portfolio theory can still be applied to Islamic investing while acknowledging faith-based investors may not always make choices solely based on rational risk-return considerations.
