US stocks were mixed Monday and the S&P 500 eked out a record high for the sixth day in a row as investors digested the announcement of a trade deal between Washington and Brussels.

Trump's trade deals with the EU and Japan pave the way for the stock market to end with it's third straight annual gain of more than 20%, Oppenheimer said.

The dollar gained against major currencies including the euro and yen on Monday with sentiment lifted by a trade agreement between the U.S. and the EU, which brings market certainty and averts a global trade war.

The U.S. and European Union agreed on trade terms that include a 15% across-the-board rate on EU products as well as hundreds of billions of dollars of investments in American industry. President Donald Trump and European Commission President Ursula von der Leyen met in Scotland on Sunday to iron out the agreement.
