Stocks moved mostly lower Tuesday as nerves rose over a politically fraught meeting between Donald Trump and China's President Xi Jinping later this week.   

The S&P 500 was down 0.22%, and the Nasdaq declined 0.15%. 

The Dow Jones Industrial Average was down 0.03% thanks to a rally in Caterpillar (CAT - Get Report) shares. The heavy machinery company jumped 2% after Goldman Sachs added it to its "Conviction Buy" list. Analysts said they are bullish given "structurally higher mid-cycle" earnings per share, management's focus on improving returns of capital, and the company's "exposure to under-invested machinery markets in the early stages of recovery. " 

Trump and Xi are set to meet on Thursday and Friday at Mar-a-Lago in Florida and are expected to discuss North Korea, trade, and currencies. Trump has been highly critical of China, accusing the country of manipulating its currency and stealing U.S. jobs. Trump recently said that if China does not help out in the fight against North Korea, the U.S. will do it on its own, though many argue China is in the unique position of being one of the only countries that could do so. 

"The most negative scenario would see Trump deliver on his campaign rhetoric, slamming a 45% tariff on U.S. imports from China," Michala Marcussen, global head of economics at Societe Generale, wrote in a note. "At the other end of the spectra, China could promise to support Trump's infrastructure plans and thus also job creation in the US ... Our baseline assumption remains that an outright trade war will be averted."

The U.S. trade deficit in February largely erased an increase seen the month earlier. The deficit fell by 9.6% to $43.6 billion in February after jumping 9.6% to $48.5 billion in January. The deficit had hit its highest level in nearly five years in the first month of the year. Imports fell 1.8% in February, while exports increased 0.2%. 

Factory orders increased 1% in February, according to the Census Bureau. The result was in line with consensus estimates. Orders had risen 1.2% in January. New orders for manufactured goods have increased in seven of the past eight months. 

Investors also were looking ahead to a back-loaded week of economic data, particularly the U.S. jobs numbers for March on Friday. It will likely be another month of strength in the U.S. labor market with 174,000 jobs expected to have been added to payrolls. The unemployment rate is estimated to have held at 4.7%, while wages are anticipated to have climbed 0.3%. Other readings on the labor market include the ADP National Employment Report for March -- the unofficial reading on private payrolls ahead of the official U.S. jobs report -- on Wednesday, and weekly jobless claims at their regular time on Thursday.

Investors will also get the rundown of what went on behind closed doors during the Federal Reserve's March meeting when minutes are released on Wednesday afternoon. At that meeting, the central bank decided to raise the federal funds rate by 25 basis points, the third interest rates increase since 2008. The decision was near unanimous with only one dissenter. The Fed also forecast two more rate hikes in 2017, in line with its previous forecasts and as markets have anticipated.
