Take a look at some of Thursday's morning movers:
General Motors - The automaker earned $0.90 per share for the second quarter, 16 cents above estimates, though revenues were slightly short of estimates.
Cigna - The health insurer earned $1.52 per share, excluding certain items, for the second quarter, beating consensus by ten cents. Revenue also beat estimates, and Cigna raised its full-year forecast as membership numbers grow.
Knight Capital - The trading firm is expected to detail the impact of yesterday's technology glitch, which resulted in irregular trading in a number of stocks. Knight said the software problem that impacted order routing yesterday has resulted in a $440 million pre-tax loss. Despite the hit to capital, Knight says it remains in compliance with capital regulations.
Costco Wholesale - The membership warehouse retail reported a 5 percent increase in same-store sales for July, above analyst estimates of a 4 percent increase.
Nike, Dick's Sporting Goods - Sporting goods-related stocks are on the watch list today after European competitor Adidas reported a slowdown in sales growth in China and Europe, although its second-quarter sales and profits did beat analyst estimates.
Hewlett-Packard - HP has won a court victory over Oracle , with a judge ruling that Oracle had an obligation to continue updating software for an HP server. Oracle has vowed to appeal.
Green Mountain Coffee Roasters - The coffee maker posted a better-than-expected quarterly profit, but lowered its outlook for 2012, as growth in its Keurig business slows. Green Mountain also authorized $500 million in stock repurchases over the next two years.
Navistar - Navistar now estimates its third-quarter revenues at $2.8 billion to $3.0 billion, versus analyst estimates of $3.5 billion. The company is also withdrawing its full year guidance until its third-quarter earnings are out next month. These revisions are related to Navistar's investments in clean engine technology.
TJX Cos. - The parent of the T.J. Maxx chain reported July same-store sales up 7 percent, above analysts' estimates, and the company also boosted its second-quarter earnings outlook.
Gap - The Gap, Old Navy, and Banana Republic parent saw July comparable-store sales come in above estimates, and says it sees second-quarter results above current Street estimates.
Target - The retailer saw July same store sales increase by 3.1 percent, above estimates of a 2.7 percent increase.
Macy's - Macy's July same-store sales rose 4.1 percent, above estimates of a 3.2 percent increase.
American Eagle - The company has raised its second-quarter guidance to $0.19 to $0.21 per share, versus analysts' estimates of $0.15. The teen retailer said sales are stronger than it had previously expected.
Abercrombie & Fitch - The American Eagle competitor is not faring quite as well: It warned that second-quarter profit will be about half of what analysts had been expecting, as it experiences a double-digit drop in same-store sales.
MetLife - The company reported second-quarter profit of $1.33 per share, nine cents above estimates. The insurer was able to negate the effects of low interest rates through its use of derivatives.
Prudential Financial - Prudential earned an adjusted $1.34 per share for the second quarter, below estimates of $1.54, but many one-time items make the comparison unclear. Prudential’s revenues did beat consensus, though core profits did slip as results in retirement solutions and investment management slipped.
Yelp - Yelp reported a second-quarter loss of $0.03 per share, narrower than the $0.06 loss analysts had been expecting. Revenue beat analysts' forecasts, and the customer review website operator raised its revenue forecast for the remainder of 2012.
Boston Beer - Boston Beer reported second-quarter profit of $1.19 per share, excluding certain items, below estimates of $1.27, with revenue also falling short of estimates. The brewer of the Sam Adams brand was impacted by increased ingredient costs and brand development spending.
Monsanto - Monsanto has been awarded $1 billion in a patent suit against DuPont. The case involved Monsanto’s “Roundup Ready” seed technology. DuPont has countersued, and that case is set to go to trial next year.
Sony - The electronics giant is reporting a larger quarterly loss for the April through June period, and has lowered its full-year earnings forecast in the face of a stronger yen and falling sales of LCD television sets.
Research In Motion - Canada's Globe and Mail reports RIM will shut down its remaining North American retail stores, with 3,000 more layoffs coming on Aug. 13.
Bristol-Myers Squibb - The drugmaker has halted a trial involving an experimental drug to treat hepatitis C due to safety concerns. The issue in question was not specified.
