The world sneezed Wednesday, but Wall Street doesn't seem to be catching cold.

Stocks have drifted lower this week, with little economic or corporate news to set the tone. In the absence of any clear catalyst, investors are taking a more cautious approach. CNNMoney's Fear & Greed index has shifted from 'Extreme Greed' to a level indicating that plain, old 'Greed' is driving the market.
Meanwhile, concerns about China's economy and a sharp drop in copper prices weighed on global markets, according to analysts at Deutsche Bank.
China has been edging to the forefront of investors' minds since February data showed exports tumbled 18% compared to last year. That followed news that the country had experienced its first-ever corporate debt default.
In recent weeks, the Chinese central bank has also loosened its grip on its currency, allowing the yuan to fluctuate more than usual, shaking confidence in what had been seen as a safe bet.
Investors have also been keeping an eye on the crisis in Ukraine, where pro-Russian militants have been cementing control of Crimea. Ukraine's interim Prime Minister arrived in Washington to meet with President Barack Obama Wednesday, before traveling to New York Thursday to address the United Nations Security Council.
