US stocks fell on Wednesday, with the Dow breaking a four-day string of record closing highs, following the World Bank's reduction of its global growth forecast.
The S&P 500's drop of 0.4% was its biggest daily percentage loss since May 20. The benchmark index fell for the second day in a row, after four straight record closing highs.
The selloff was broad. Every S&P 500 sector index except energy declined for the day.
Low volume and low volatility have marked recent sessions, leaving indexes to trade in a narrow range.
The World Bank's lower growth forecast provided investors with a reason to unload some stocks. Late Tuesday, the World Bank cut its global economic growth forecast for 2014 to 2.8% from 3.2% because of a harsh US winter and the impact of the Ukraine crisis.
"It's pretty quiet. The only news investors are keying in on is the forecast of slightly lower global growth," said Dan Veru, chief investment officer of Palisade Capital Management LLC in Fort Lee, New Jersey, which oversees $4 billion.
"I think it's an excuse for some investors to take some money off the table."
The biggest drag on the S&P 500 was Bank of America Corp, down 2.1% at $15.59. The bank has reached an impasse in negotiating a multibillion-dollar settlement with the US Department of Justice related to the bank's mortgage investments, according to The New York Times.

Even as the Dow and the S&P 500 retreated from recent gains, the PHLX semiconductor index kept up its rally. The SOX rose 0.5%, extending its winning streak to 15 days, its longest stretch of gains since the index was created about 20 years ago.
Leading the SOX higher, Micron Technology Inc rose 5% to $30.99 a day after Credit Suisse raised its price target on the memory chipmaker's stock to $50 from $30.
