Investors brave enough to dip their toes into the Egyptian stock market have been rewarded handsomely this year.

Egypt is finally returning to stability following prolonged periods of chaos after the Arab Spring revolutions that ousted former Egyptian strongman Hosni Mubarak.

New President Abdel Fattah el-Sisi has introduced a number of economic reforms that have been applauded by foreign investors.

Against that backdrop, the Market Vectors Egypt ETF (EGPT) has climbed about 33% so far this year. The fund is heavily skewed toward the financial sector, where nearly 50% of its assets are located. It's also got significant exposure to Egypt's telecom sector and materials stocks.

But investors who go long on Egypt need to beware of the threat of political unrest. After all, this is a country that's had two revolutions in just the past five years.
