Despite recent upside momentum that has seen shares of Cheniere Energy (LNG -0.36%) jump over 71% since mid-September and news that the company reached a deal with Bechtel to build new liquefied natural gas (LNG) assets, there could be some headwinds for the company. First, those new assets won't be operational until 2018. Second, the issue that could freeze Cheniere's stock really comes down to global shale developments, which could challenge the economics of building infrastructure for LNG and shipping it via sea. Finally, investors have been expecting the debut of the Cheniere Energy Partners LP (CQP 0.56%) IPO so this may be a sell-the-news event for shares of LNG once the deal comes to market officially.
