Aug 13 (Reuters) - U.S. stocks finished flat on Thursday as a drop in energy shares offset a rebound in retail sales and stronger-than-expected Cisco results.
The S&P energy index dropped 1.4 percent, leading the decline in the S&P 500, as U.S. crude oil prices slid to a 6-1/2-year low.
The S&P consumer discretionary index rose 0.6 percent, the most among the major 10 S&P sectors, but it had been higher earlier.
U.S. retail sales rose in July, while the trend of weekly jobless claims pointed to a tightening job market. The data supported the view the Federal Reserve could raise interest rates as early as next month, offsetting speculation in the previous two sessions that the Fed could wait until December to raise rates after China devalued its currency.
Jitters over China remained. Sources had told Reuters this week that some powerful voices in the government were pushing for an even deeper yuan devaluation to help China's struggling exporters.
"The market is still adjusting to the Chinese devaluation. Obviously, that's created a lot of uncertainty, and people are not sure how this is going to play out," said Michael O'Rourke, chief market strategist at JonesTrading in Greenwich, Connecticut.
Cisco jumped 2.9 percent to $28.70, giving the biggest boost to the Nasdaq and the S&P 500.
The Dow Jones industrial average rose 5.74 points, or 0.03 percent, to 17,408.25; the S&P 500 lost 2.66 points, or 0.13 percent, to 2,083.39; and the Nasdaq Composite dropped 10.83 points, or 0.21 percent, to 5,033.56.
The S&P financial index rose 0.3 percent, after falling in the previous two sessions.
In corporate news, retailers posted mixed quarterly results.
Kohl's fell 8.8 percent to $56.11 after its same-store sales missed expectations. After the bell, shares of Nordstrom's rose 5.7 percent following its results.
During the regular session, News Corp rose 7.6 percent to $15.19 after the Wall Street Journal owner's profit topped estimates, helped by cost cuts at its news business, including Dow Jones.
Also, shares of Shake Shack Inc dropped 15.9 percent to $54.49 in its biggest one-day percentage decline since its debut, after the company said it had priced a 4 million-share offering at $60 per share, well below a $64.79 closing price on Wednesday.
Tesla rose 1.8 percent to $242.51 after unveiling plans to raise about $500 million through a share sale, with Chief Executive Officer Elon Musk buying shares worth up to $20 million.
Declining issues outnumbered advancing ones on the NYSE by 1,821 to 1,204, for a 1.51-to-1 ratio on the downside; on the Nasdaq, 1,575 issues fell and 1,237 advanced for a 1.27-to-1 ratio favoring decliners.
The benchmark S&P 500 index posted 25 new 52-week highs and nine new lows; the Nasdaq Composite recorded 51 new highs and 76 new lows.
About 6.2 billion shares changed hands on U.S. exchanges, compared with the 7.1 billion daily average for the month to date, according to data from BATS Global Markets. (Additional reporting by Tanya Agrawal in Bengaluru; Editing by Meredith Mazzilli, Nick Zieminski and Jonathan Oatis)
