United States Commodity Funds lists products on Mexican Stock Exchange

August 28, 2013, Oakland, CA - USCF announced today that five of its exchange traded products (ETPs) are now listed on the Mexican Stock Exchange, Bolsa Mexicana de Valores in Spanish (BMV). The ETPs available on the BMV are United States Oil Fund, LP (USO), United States Natural Gas Fund, LP (UNG), United States 12 Month Oil Fund, LP (USL), United States Gasoline Fund, LP (UGA) and the United States Commodity Index Fund (USCI).

USCF’s Chief Investment Officer John Hyland said: "We are pleased to list these products on the BMV, as this opens up a significant new market for our products. We think the BMV is the most important exchange in Latin America as it serves both the fast-growing Mexican economy and is a key exchange for the rest of Latin America. As Mexican institutions and investors are becoming increasingly sophisticated, they are interested in alternative investments as well as Mexican equities and fixed income. Now that Mexican investors can trade these ETPs in pesos, we hope they'll benefit from the liquidity and transparency these products provide."

United States Commodity Funds LLC manages 12 ETPS that focus on commodities. These funds are designed to track the performance of commodity futures contracts, and USCI seeks to track an index based on the daily price movements of a broad basket of commodities.

Located in Mexico City, the BMV is the second largest securities exchange in Latin America, after Brazil. The BMV is the public marketplace for both Mexican and non-Mexican listed securities.
