When oil lost almost $3 a barrel, stock futures indicated a lower opening for today. Just shy of 5 AM, S&P 500, Down Jones, and Nasdaq 100 futures were all off 0.9%. The drop in oil to $64 a barrel has called into question any projections of a quick economic recovery -- as if high unemployment weren't enough. The Monday after any long weekend is hard, and this one's going to hurt.

The direction in which futures are pointing continues Thursday's equity declines in the United States, bringing the S&P 500 its third consecutive weekly loss. For the day, it lost 2.91%. The Dow Jones Industrial Average lost 2.63% of its value, with the Nasdaq Composite Index giving up 2.67%. Year-to-date, the DJIA is down 5.6%, the S&P 500 down 0.8%.

MOST NOTEWORTHY: Acergy, Casey's General and Corinthian Colleges were today's noteworthy downgrades:

• Citigroup downgraded shares of Acergy (NASDAQ: ACGY) to Sell from Hold as they see risk to the company's backlog and believes the recent share rally is not supported by business operations.
  
• Casey's General (NASDAQ: CASY) was downgraded at Friedman Billings to Underperform from Market Perform citing headwinds that include weak gas comps.
  
• Banc of America downgraded shares of Corinthian Colleges (NASDAQ: COCO) to Neutral from Buy as they believe the post-legislation lending overhang will limit further share upside until COCO can show its students can access federal funds with minimal disruption.

OTHER DOWNGRADES:

• Bernstein cut EMC Corp (NYSE: EMC) to Market Perform from Outperform.
  
• Baird lowered Woodward Governor (NASDAQ: WGOV) to Neutral from Outperform.
  
• Merrill downgraded Sealed Air (NYSE: SEE) and Bemis (BMS) to Sell from Neutral.
