U.S. HOT STOCK FUTURES: HOT STOCKS TO WATCH

Among the companies with shares expected to actively trade in Thursday's session are Green Mountain Coffee Roasters Inc. (GMCR), Rackspace Hosting Inc. (RAX) and Monster Beverage Corp. (MNST).

Green Mountain Coffee's fiscal second-quarter earnings rose 42% from stronger sales of its Keurig single-serve coffee packs and lower green coffee costs boosted margins. Shares jumped 16% to $69.25 after hours.

Rackspace reported another quarter of slowing revenue growth as price cuts and weaker-than-expected demand hurt the data-center operator's top line. Shares sank 17% to $43.59 after hours Wednesday on the disappointing sales result, accelerating the company's 30% year-to-date decline.

Monster Beverage's first-quarter earnings fell 17% as expenses related to litigation and distributor changes hurt the energy-drink maker's bottom line. Shares dropped 13% after hours Wednesday to $49.81 as results fell short of analyst expectations.

Groupon Inc.'s (GRPN) first-quarter loss narrowed as the daily-deals website posted stronger revenue and significantly cut back on marketing costs, though margins continued to slide. Shares jumped 11% after hours to $6.21 after the company beat revenue expectations in the latest period.

 
  Watchlist: 
 

Activision Blizzard Inc. (ATVI) reported better-than-expected first-quarter results but provided cautious guidance for the rest of the year because of concerns about the next-generation videogame consoles and a decline in the company's key "World of Warcraft" fantasy game.

CenturyLink Inc.'s (CTL) first-quarter earnings rose 49% amid lower costs as the telecommunications company reported that continued access-line losses offset growth at its broadband and Prism television businesses. Adjusted earnings beat expectations and the company raised its 2013 earnings outlook.

Ctrip.com International Ltd.'s (CTRP) first-quarter profit slid 26% as the Chinese travel website saw expenses grow, offsetting stronger revenue. But results sharply topped analysts' estimates and its second-quarter revenue view topped consensus projections.

Highfields Capital Management's founder Jonathon Jacobson delivered a blistering attack on a real-estate investment trust that focuses on housing data-centers, Digital Realty Trust Inc. (DLR). Mr. Jacobson, who doesn't typically talk about short positions, criticized the company's dividend payments and suggested the stock could fall to as low as $19 from its close of $69.02 on Wednesday.

News Corp.'s (NWS, NWSA, NWS.AU) profit nearly tripled in the quarter ended March 31, boosted by one-time gains and better results from its cable networks segment. Meanwhile, the publishing unit, to be spun off as a separate company in coming months, posted sharply lower operating income.

Polypore International Inc.'s (PPO) first-quarter earnings fell 52% as continued weak demand for lithium battery separators offset sales growth in the company's other businesses.
