On some stock markets, there's reportedly a "Ramadan Effect," a month-long rally. "During the Holy Month, we find that on average, stock returns are almost nine times higher in predominantly Muslim countries than during other times of the year," finance professor Ahman Etebari recently told the Voice of America.
However the holy month also means holy food, such as dates which Muslims are encouraged to break their fast with.
In the U.S., the market for halal-certified foods has soared in the past decade. The Islamic Food and Nutrition Council of America (IFNCA) recently estimated an 80% growth in the market for halal-certified ingredients and food products since 2005. "This increased interest for U.S. halal market ingredients and products," according to the IFNCA statement, "may reflect the overall estimated $170 billion U.S. dollar purchasing power of American Muslims."
In the Muslim world. this month also means new clothing, homewares, furniture and special entertainment. Ramadan ends with Eid Al Fitr, a celebration of feasts and gift-giving. Like Hanukkah or Christmas, Eid and other Muslim holidays have become major sales opportunities for retailers.
But the main highlight of Ramadan is the pilgrimage to Mecca. Pilgrimage visas are 1.1 million up on 2010 making for an unprecedented rise in one of Saudi Arabia's most important sources of non-oil revenue.
