The advance in financials was underpinned by a 2.6 percent jump in shares of Morgan Stanley, which reported a surge in quarterly profit. Shares of other big U.S. banks rose in tandem.
Morgan Stanley's solid results provided some succor to investors stung by weak results at chief rival Goldman Sachs a day earlier.
IBM sank nearly 6 percent to $16.06 after the company reported a bigger-than-expected decline in revenue for the first time in five quarters. The stock was the biggest drag on the Dow and the S&P.

Mounting tension between North Korea and the United States and political uncertainty in Europe ahead of the French presidential elections had kept safe-havens such as gold and U.S. Treasuries in demand in the past weeks.
