New York - US stocks fell on Thursday as concerns escalated about Iraq and after disappointing economic data on retail sales and jobless claims.
The three major US stock indexes ended off their session lows. With the day's decline, though, the S&P 500 was down for three straight sessions for the first time since early April.
The Dow Jones industrial average lost more than 100 points for the second day in a row.
Hours after ethnic Kurdish forces took control of the oil hub of Kirkuk after the Shi'a-led government's troops abandoned their posts, President Barack Obama was asked if he might order drone strikes or other action to halt the insurgency that has seized much of northern Iraq this week.
Obama told reporters that he refused to rule out US action in Iraq against Sunni Islamist militants who have surged out of the north toward Baghdad, threatening to divide the country and establish their own jihadist state.
The stock market's losses quickly accelerated following Obama's comments, with industrials and consumer discretionary sectors leading the decline.
The CBOE Volatility Index or the VIX, Wall Street's “fear gauge,” shot up 8.3 percent to end at 12.56.
State Department spokeswoman Jen Psaki followed Obama's comments by telling a daily briefing that the administration was considering all options, except for sending US troops into Iraq.
“It's a bit of a crisis mode here. Geopolitical concerns have definitely taken over. It's a very fluid situation and things are happening very fast, it seems,” said Timothy Ghriskey, chief investment officer of Solaris Asset Management LLC in New York.
The Dow Jones industrial average fell 109.69 points or 0.65 percent, to end at 16,734.19. The S&P 500 slid 13.78 points or 0.71 percent, to 1,930.11. The Nasdaq Composite dropped 34.30 points or 0.79 percent, to 4,297.63.
The Dow touched an intraday low at 16,703.73, while the S&P 500 fell as low as 1,925.78, and the Nasdaq slid to a session low at 4,284.528.
In macroeconomic news, retail sales rose 0.3 percent in May, half the growth rate that economists had forecast. Americans' new claims for unemployment benefits unexpectedly rose last week.
While both economic indicators were below expectations, neither was seen as so weak as to change the perception of improving economic conditions, and the market's recent uptrend is still viewed as intact.
Energy shares ranked among the few gainers on Thursday. The S&P energy sector index was up 0.3 percent. Oil prices hit nine-month highs on worries that escalating violence in Iraq could disrupt oil supplies from the major Opec exporter.
