U.S. advisers who are not alert to the special investing needs of Muslims are missing an attractive segment of the investing populace. The U.S. Muslim population is expected to reach 6.2 million by 2030, almost three times the nation's 2.6 million Muslims in 2010. Muslim-Americans are younger and better educated than the average U.S. citizen. Moreover, they want to see a greater number of appropriate financial products. Meeting their investing needs is similar to working with clients who want socially responsible investments, but it requires additional expertise. But the main point is that advisers can help Muslims get in the market.
