Investors were eyeing tensions in Iraq and rising oil prices Thursday. That caused stocks to drop sharply in late-day trading.

Also reported Thursday were retail sales numbers. The numbers disappointed investors and were less than expected. Retail sales rose less than expected, up 0.3 percent versus a 0.5 percent expectation. 

The retail sales numbers for April were revised to raising 0.5 percent from the 0.1 percent rise that was previously reported.

Tensions in Iraq are rising, and that could be contributing to rising oil prices. Crude oil is up 1.5 percent to $105.97 a barrel.

Because of raising oil prices, transport stocks took big hits Thursday. United Continental Holdings (United Airlines), Delta Airlines and JetBlue Airways all fell steeply.

Shortly after 3 p.m., the Dow Jones Industrial Average is down 120 points. 

The S&P 500 is down 15 points or 0.79 percent. Utilities are among the leaders that lost the most Thursday.

The CBOE Volatility Index or the VIX, which measures investor uncertainty, was up over 8 percent Thursday, indicating that investors are not confident in the market. This caused gold prices to rise 0.9 percent, up to $1,272.50 an ounce.
