Another wild day as the Dow dropped 60 points right out the gate, only then to steadily zoom up 140 points throughout the day until 3 p.m., then lose all but 5 before the close.  So what were the opposing forces of nature behind this drop and zoom?  Oil dropping to a 6-1/2 year low was the drop and strong retail numbers for July along with steady new jobless claims indicating the employment market holding solid with no new losses triggered the zoom.  Then in the last hour, it occurred to investors that all this good news is exactly what the Fed is looking for to hike interest rates in September so all the gains were lost.  The uncertainty with China didn't help either.  Volume was below the month's average at 6.2 billion.

Wall St. ends flat as energy shares drop with oil

REUTERS/BRENDAN MCDERMID

DJ:     17,408.25  +5.74      NAS:  5,033.56  -10.83         S&P:  2,083.39  -2.66

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 .SPNY 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 .SPLRCD 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 (CSCO.O) jumped 2.9 percent to $28.70, giving the biggest boost to the Nasdaq and the S&P 500.

The Dow Jones industrial average .DJI rose 5.74 points, or 0.03 percent, to 17,408.25; theS&P 500 .SPX lost 2.66 points, or 0.13 percent, to 2,083.39; and the Nasdaq Composite.IXIC dropped 10.83 points, or 0.21 percent, to 5,033.56.

The S&P financial index .SPSY rose 0.3 percent, after falling in the previous two sessions.

In corporate news, retailers posted mixed quarterly results.

Kohl's (KSS.N) fell 8.8 percent to $56.11 after its same-store sales missed expectations. After the bell, shares of Nordstrom's (JWN.N) rose 5.7 percent following its results.

During the regular session, News Corp (NWSA.O) 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 (SHAK.N) 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 (TSLA.O) 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. [ID:nL3N10O4CX]
