Carl Icahn raised his stake in Cheniere Energy LNG, +1.24% to 9.59% from 8.18%, the billionaire investor reported in a regulatory filing on Monday. Icahn now owns 22,682,159 shares in the energy company, according to a filing with the Securities and Exchange Commission, up from the 19,353,530 shares reported on Aug. 31. Icahn appears to be slugging it out with noted short seller Jim Chanos, the founder of Kynikos Associates, who told CNBC last week that he was shorting, or betting against, Cheniere. Cheniere shares were up 2.9% in after-hours activity. marketwatch
