What is it about?

The paper explores risk ad return performance, efficiency of and co-movement between Islamic and unrestricted portfolios in developed and emerging markets.

Why is it important?

Unlike unrestricted portfolios, Islamic portfolios have a narrow opportunity set for investment. They also face trading restrictions due to the prohibition of futures, short selling, options and day trading which can potentially create significant limits to arbitrage. This research explores comparative performance, efficiency and co-movement of Islamic and unrestricted portfolios.
