Stocks: Spain in focus

Click on chart for more premarket data.

U.S. stocks were set to close out the third quarter Friday, with investors balancing global growth concerns and hope that Spain will soon ask for a bailout from neighbors.

Investors will be focused on Europe after the release of Spain's 2013 budget on Thursday. The proposed budget boosted U.S. stocks late Thursday, as many interpreted it as a sign the country is willing to take necessary steps to avert a deepening crisis. But that relief may prove ephemeral as concerns about Spain remain.

Spanish banks will receive auditors' results of stress tests, which will give investors a clearer view of the area's economic struggles. The nation's bonds could also be in for a downgrade from Moody's, according to reports. Yields for the 10-year Spanish bond pushed above 6% again on Friday.
