The Dow Jones Industrial Average's road to 20,000 had another detour on Monday as a selloff in crude oil dragged on the energy sector and soured sentiment.
The Dow slid 0.37% to 19,888 on Monday, though remained one rally away from clinching its next milestone. The S&P 500 was down 0.35%.
The Nasdaq was the only index in the green on Monday, rising 0.19% and reaching another record close of 5,531. Deals-related rallies in health care helped to boost the index.
Merrimack Pharmaceuticals(MACK) - Get Report was 1.9% higher after drugmaker Ipsen agreed to buy some of its assets, including its drug for pancreatic cancer, in a deal worth more than $1 billion. Merrimack also said it would eliminate about 80% of its staff as it refocuses its pipeline.

Dow 20,000 came agonizingly close on Friday, but building momentum flagged in the final moments to fall short of the milestone. The Dow came within a point of the level in the afternoon session before backing off, just as it has for weeks. The S&P 500 and Nasdaq each closed at fresh records on Friday.
Crude oil prices fell below $53 a barrel on Monday, continuing to trade off of data late Friday that showed rising U.S. production. A weekly reading on U.S. activity showed the number of U.S. oil rigs climb for the 10th consecutive week in a row.
Commodities trading has been erratic in the past week as investors weigh U.S. production against an agreement among major oil-producing nations designed to rebalance markets. A production cut agreement among Organization of Petroleum Exporting Countries and other non-OPEC producers took effect at the beginning of the year.
"With the market having already attracted a large volume of buying in anticipation of a rebalance market and months of price gains on the announcement of talks, the progress of talks, and the announcements of the production cut agreements, the market runs the risk of a "sell the news" reaction even if compliance is relatively good," said Tim Evans, energy futures specialist at Citi, in a note.
West Texas Intermediate crude closed 3.8% lower at $51.96 a barrel on Monday, its lowest level since mid-December.
The energy sector was the worst performer on Monday. Major oilers including Exxon Mobil(XOM) - Get Report , Chevron(CVX) - Get Report , Halliburton(HAL) - Get Report and Marathon Petroleum(MPC) - Get Report slid, while the Energy Select Sector SPDR ETF (XLE) - Get Report fell 1.4%.
Wall Street was also adopting a wait-and-see approach ahead of fourth-quarter earnings later this week. The big banks, as usual, will be among the first to report earnings. Bank of America(BAC) - Get Report , JPMorgan(JPM) - Get Report and Wells Fargo(WFC) - Get Report will report on Friday.
Average earnings for the S&P 500 in the fourth quarter are expected to increase 4.4% from the same period a year earlier. Earnings growth would mark the second straight quarter of gains after the third quarter broke an earnings recession that lasted for four consecutive quarters. Earnings grew 4% in the third quarter of 2016.
The U.S. economy warrants "somewhat more regular" interest rate hikes, Boston Federal Reserve President Eric Rosengren said on Monday. In a speech in Hartford, Conn., Rosengren said the "economic circumstances have evolved and now imply the need for a different stance of monetary policy." Rosengren is a voting member of the Federal Open Market Committee this year.
Atlanta Fed President Dennis Lockhart brought a more dovish take on Monday afternoon, arguing that the U.S. economy isn't likely to breach higher than 2% growth. In a speech in Atlanta, Lockhart said the U.S. economy would likely reach 2% next year but no higher. "It's less certain that the economy is positioned for a breakout to markedly higher growth on a sustained basis," Lockhart said.
Pet health care company VCA (WOOF) agreed to be acquired by Mars Inc. on Monday in a deal worth $9.1 billion.

VCA shares jumped 28%.
Alibaba(BABA) - Get Report shares moved almost 1% higher after its CEO Jack Ma met with President-elect Donald Trump at Trump Tower. Trump and Ma characterized the meeting as successful and said the focus was on jobs and small business.
Fiat Chrysler(FCAU) - Get Report added 1.4% after outlining plans to invest $1 billion in plants in Michigan and Ohio, adding 2,000 new jobs to the U.S. The move comes after President-elect Trump took aim at a number of automakers via Twitter in which he criticized any plans to ship jobs out of the U.S. and threatened to impose border taxes.
