Stocks rose on Wednesday after stronger-than-expected Dell earnings and a flurry of deal news, but concern about tensions between Israel and Iran gave investors reason to pause.
Israel's foreign minister said two Iranian warships planned to sail through the Suez canal en route to Syria and hinted at an Israeli response, pushing oil prices back up to $85 a barrel.
Stocks at first showed little reaction to the statement, but slowly began to fall toward sessions lows.
The benchmark S&P 500 earlier broke above 1,333.58, double the intraday low hit in early March 2009, and was trading just below that level after midday.
With a market that has run as far and fast as this one has, clearly negative headlines, like the ones about Israel and Iran, can have a negative impact, said Gary Flam, portfolio manager at Bel Air Investment Advisors in Los Angeles.
Stocks have been rallying since early September, with the S&P 500 up more than 25 percent in that time.

In another proposed deal, activist investor Nelson Peltz's Trian Group offered to acquire Family Dollar Stores Inc
Merger and acquisition activity has picked up, raising investor hopes it will bring more fresh cash into the market.
It seems as if the market has a very strong bid underneath stock prices. There seems to be a desire to get invested. So any time there's a pullback, if the next day there's a hint of good news, the market bounces back, said Eric Kuby, chief investment officer at North Star Investment Management Corp in Chicago.
