A pair of corporate mergers failed to boost the broader market Monday as investors await comments from Federal Reserve officials later in the week.

The Dow Jones industrial average, the S&P 500 and the Nasdaq all ended about 0.1% lower.

Traders were wary of pushing stocks higher after the Dow and S&P 500 capped a four week winning streak Friday with new record highs.

"It's a slow day," said Peter Tuz, portfolio manager at Chase Investment Counsel. "We've got some more important Fed news and economic statistics later in the week."

Bernanke takes the stand: Investors will pay close attention to comments from Federal Reserve officials this week, including chairman Ben Bernanke, who will testify before Congress Wednesday.

All three major U.S. indexes have gained around 16% so far this year on a combination of gradually improving economic data and continued support from the Fed.

But investors have been rattled recently by comments from some Fed officials suggesting the central bank could begin to scale back its bond-buying program sooner than expected.

"There's a tug-of-war within the Fed about an exit strategy," said Tuz. "We should hear more about that this week."

The yen also rises: The yen edged up 0.7% versus the U.S. dollar Monday after Japan's economy minister suggested further weakness could be harmful to Japan's recovery efforts.

The yen has plunged 15% against the dollar this year as Prime Minister Abe and the Bank of Japan launched an aggressive campaign to boost the nation's economy.
