2. -- The economic calendar in the U.S. on Thursday includes weekly initial jobless claims at 8:30 a.m. EDT, the second estimate of second-quarter GDP at 8:30 a.m., and pending home sales for July at 10 a.m.

3. -- U.S. stocks on Wednesday flitted in and out of positive territory throughout the entire trading session and the S&P 500 ended almost where it was after Tuesday's closing -- just above 2,000. The markets were trading indecisively throughout the day, catching their breath in the absence of any new economic catalysts.

The Dow Jones Industrial Average closed up 0.09% to 17,122.01. The S&P closed flat at 2,000.12. The Nasdaq fell 0.02% to 4,569.62.

4. -- The FBI is investigating a computer-hacking attack on JPMorgan Chase (JPM) and as many as four other banks, The Wall Street Journal reported, citing people familiar with the probe. The attacked was described as a significant breach of corporate computer security.

Cybersecurity experts began probing the possible JPMorgan breach earlier this month, according to people familiar with the investigation.

Those people said the evidence gathered so far suggested hackers were able to make a significant foray into the bank's computer system, the Journal reported. People with knowledge of the investigation said it appeared between two and five U.S. banks may have been affected. The names of all targeted banks couldn't be immediately determined, the Journal said.

JPMorgan isn't seeing considerable fraud related to the attack, a person familiar with the matter said. 

The attack appears to have been caused by malicious computer code, known as malware, according to a person familiar with the matter, the Journal reported.

5. -- A federal judge rejected Apple's (AAPL) attempt to block the sale of several older Samsung smartphones that copied features in the iPhone.

The rebuff on Wednesday comes nearly four months after a jury awarded Apple $119 million in damages for Samsung's infringements on technology used in the iPhone. The amount was well below the $2.2 billion in damages that Apple had been seeking in the latest round of legal wrangling between the world's two leading smartphone makers since the tussle began four years ago.

Apple wanted U.S. District Judge Lucy Koh in San Jose, Calif., to issue an order that would have prevented future U.S. sales of nine Samsung phone models that infringed on the iPhone technology.

6. -- Dollar General (DG) , the nation's largest dollar-store chain, is expected by analysts on Thursday to report second-quarter earnings of 83 cents a share on revenue of $4.77 billion.

Dollar General is involved in a bidding war for rival Family Dollar (FDO) . Earlier this month, Dollar General bid about $8.95 billion for Family Dollar in an attempt to trump Dollar Tree (DLTR) , which agreed to acquire Family Dollar for $8.5 billion in July.

7. -- Wall Street expects retailer Abercrombie & Fitch (ANF)  on Thursday to report second-quarter profit of 11 cents a share on sales of $909.2 million.
