U.S. equities closed mixed in choppy trade on Monday, the first day of the month, amid falling oil prices while investors digested economic data.
The Dow Jones industrial average closed 27 points lower, erasing earlier gains, with Chevron (CVX) and ExxonMobil (XOM) contributing the most losses. The blue-chips index also extended its losing streak to six days. At its session lows, the Dow traded 76.49 points lower. The S&P 500 traded about 0.13 percent lower, with energy falling more than 3 percent. Earlier, the benchmark index hit a new all-time intraday high.
"You've almost got a tale of two markets," said Art Hogan, chief market strategist at Wunderlich Securities. "Part of that is getting used to the new normal in energy prices." "You've got tech names like Apple and biotech helping the Nasdaq."
The Nasdaq composite ended 0.4 percent higher, well off session highs, with Apple and as the iShares Nasdaq Biotechnology ETF (IBB) both rising more than 1.5 percent.
Oil prices were under pressure Monday, with U.S. crude futures (New York Mercantile Exchange: @CL.1) settling 3.7 percent lower, at $40.06 after briefly dipping below $40 .
"We've had a breakdown in the correlation between oil and the market since we broke above $40," said Randy Frederick, managing director of trading and derivatives. "If we break below $40, that could be a problem."
U.S. crude has fallen from about $46.50 a barrel to its current levels in just ten days, according to FactSet.
"To go from $50 to $40 is essentially a bear market," said Jack Ablin, chief investment officer at BMO Private Bank.
On the data front, the ISM manufacturing index came in at 52.6, slightly below Reuters' estimate of 53. Any number above 50 indicates expansion. The Markit PMI manufacturing index reading for July came in at 52.9. Construction spending for June declined 0.6 percent.
Kim Forrest, senior equity analyst at Fort Pitt Capital, said "I think the economic news was spot on. There' a little disappointment in construction spending, but it's tough for that kind of month-to-month data, since it factors in weather" and other elements.
"Bottom line, notwithstanding the slight decline [month over month], manufacturing in the US has stabilized with the ISM index above 50 for the 5th straight month and a touch above the 6 month average of 51.5," Peter Boockvar, chief market analyst at The Lindsey Group, said in a note to clients.
Investors will also keep an eye on more corporate quarterly reports as earnings season carries on. "I think that what's going to happen this week will be heavily dependent on earnings," said Maris Ogg, president at Tower Bridge Advisors.
Drilling contractor Diamond Offshore (DO) reported earnings per share before the bell that were 3 cents above estimates, while movie theater operator AMC Entertainment (AMC) missed expectations by 2 cents. Williams Cos., General Growth Properties and Vornado Realty are among the firms scheduled to report after the bell.
Later this week, AIG, Tesla Motors, Kraft Heinz and LinkedIn, among others, will report earnings for their latest quarters.
As of Friday's close, 63 percent of S&P 500 companies had reported second-quarter results, Nick Raich, CEO at The Earnings Scout, said in a note to clients. "For current stock prices, what happened during the 2Q 2016 no longer matters. Instead, it is all about the direction of 3Q 2016 EPS expectations," he said.
Raich said that earnings-per-share growth expectations had fallen to 0.87 percent from 1.35 percent last week. "At a similar point in time last quarter, [second-quarter] 2016 EPS growth expectations were -2.64%, which indicates growth rates are likely to improve more in the [second half] of 2016."
U.S. Treasury prices fell broadly, with the two-year yield rising to 0.68 percent and the benchmark 10-year yield trading near 1.51 percent. The dollar rose slightly against a basket of currencies — after falling about 2 percent last week — with the euro trading near $1.117 and the yen at 102.4.
This week will feature July's U.S. jobs report, something investors will eye closely as they gauge what the Federal Reserve's next monetary policy move will be.
That said, Tower Bridge's Ogg said she doesn't expect the central bank to move rates higher in the near term. "This is one of the most gutless Fed's I've ever seen. My opinion is the Fed should've raised rates a long time ago," she said.
"We're going to get a fair amount of economic data globally, but I think the real exclamation point is going to be Friday," BMO's Ablin said.
Overseas, Asian equities mostly climbed, with the Nikkei 225 and the Hang Seng advancing 0.4 percent and 1 1.09 percent, respectively. However, Chinese stocks fell broadly, with the Shanghai composite shedding nearly 1 percent as trades digested Chinese PMI data.
European stocks traded mostly lower, with the German Dax falling 0.07 percent and the FTSE 100 rising 0.03 percent. European banks, meanwhile, fell as traders reacted to banking stress tests in the region.
The Dow Jones industrial average (Dow Jones Global Indexes: .DJI) closed 27.73 points lower, or 0.15 percent, at 18,404.51, with ExxonMobil as the greatest decliner and Apple the top advancer.
The S&P 500 (^GSPC) ended 2.76 points lower, or 0.13 percent, to 2,170.84, with energy leading six sectors lower and health care the biggest riser.
The Nasdaq (^IXIC) closed 22.06 points, or 0.43 percent, to 5,184.20.
The CBOE Volatility index (VIX) (^VIX), widely considered the best gauge of fear in the market, traded higher, near 12.63.
About four stocks declined for every three advancers at the New York Stock Exchange, with an exchange volume of 841.46 million and a composite volume of 3.416 billion at the close.
Gold futures for December delivery settled $2.10 higher at $1,359.60 per ounce.
