The Roundhill Alerian LNG ETF LNGG, listed on NYSE Arca on September 22, provides access to U.S. and international companies materially engaged in the LNG industry. LNGG is the first ETF providing focused exposure to the global LNG market. LNGG is based on the Alerian Liquefied Natural Gas Index ALNGX. The index consists of companies focused on liquefaction, shipping LNG (LNG carriers), as well as regasification. The index also includes diversified LNG companies that participate in more than one of the three segments. LNGG’s underlying index comprises 28 constituents, with about 40% of the index by weight in U.S. companies. At time of launch, Cheniere Energy (LNG), a pure-play liquefaction company, is LNGG’s largest holding. LNG, or liquefied natural gas, is natural gas that has been cooled to a liquid state. Compared to natural gas, LNG is about 600 times smaller. This makes LNG more suitable for transportation and storage, according to Stacey Morris, head of energy research at VettaFi.
