Monday's After-Hours Movers Include Gilead, Barrick Gold, TerraForm, Energy XXI & Wynn Resorts, Among Others

Shares of Gilead Sciences, Inc. GILD are up 0.42 percent in after-hours Monday on relatively high volume (more than 2.1 million shares), after gaining 0.54 percent over the trading session. The surge was driven by the approval of its hepatitis C virus (HCV) drug Harvoni in Japan.

Among the biggest gainers after the bell is TerraForm Power Inc TERP, which is up 3.54 percent to $38.86 per share. TerraForm, a unit of Sunedison Inc SUNE, which is also up more than 3 percent in after-hours, announced, after the market closed, that it would acquire 930 megawatt of wind power plants from Invenergy Wind LLC, in a transaction that will total $2 billion.

On the other hand, Energy XXI Ltd EXXI’s stock, which tumbled 3.46 percent over the day, fell an extra 1.35 percent in after-hours, to $2.20. The decline was, of course, triggered by the falling prices of WTI and Brent crude futures, amid a strong U.S. dollar environment.

Wynn Resorts, Limited WYNN surged 0.33 during Monday trading, and an extra 1.56 percent since the bell rang, on –apparently- no particular news. The stock is trading at $105.50.

Liberty Global PLC LiLAC Class A LILA fell 3.19 percent in after-hours, after climbing 0.79 percent during the day.

Accuride Corporation ACW seems to be recuperating from the 2.58 percent decline it experienced on Monday, as it is up 0.8 percent in late trading. Once again, no particular events seem to have triggered today’s move.

SouFun Holdings Ltd SFUN plummeted 14.3 percent on Monday, to $7.13, after the company announced the results of its 2015 annual general meeting of shareholders, held last Friday. The stock is recuperating in after-hours (up 3.26 percent) on moderate volume.

Rising gold prices sent Barrick Gold Corporation (USA) ABX up 2.65 percent on Monday. However, the stock is losing most of the gained ground in after-hours, which are seeing the stock down almost 2 percent.
