Who said big oil was a dying business? Fortune has released its Global 500, their "annual ranking of the world's largest corporations," and topping the charts is Royal Dutch Shell (NYSE: RDS.A), which, much like a Mariah Carey song, bumped up into the coveted number-one slot after some time at number three. The Netherlands-based oil company trumped its U.S. rival, Exxon Mobil (NYSE: XOM) by $15 billion in sales and saw its revenue spike nearly 29% from 2007.

Speaking of Exxon, the company once again had a tiger in its tank, ranking number two in the world as oil futures bounced around in a nearly $100-dollar range, hitting $146 per barrel at its heights.

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%.

The second half of the calendar year has begun, and earnings return to the spotlight this week. As usual, Alcoa Inc. (NYSE: AA) is among the first of the S&P 500 to report quarterly results. For the second quarter in which Alcoa agreed to sell its wire harness and electrical distribution business and its fastening systems business expanded into Morocco, analysts surveyed by Thomson Reuters expect the New York-based aluminum producer to report swinging to a net loss of $0.34 per share from a profit of $0.66 per share in the year-ago period. Second quarter revenue is expected to have fallen 48.3% to $3.9 billion. The full-year forecast is currently for a loss of $1.04 per share and revenue of $16.7 billion (-38.0%). Alcoa has missed expectations in the past three quarters, by as much as 17 cents per share. The long-term EPS growth forecast is 10.0%, which is better than the sector average. Alcoa slashed its dividend earlier this year, and the First Call consensus recommendation remains to hold AA. However, TheStreet.com recommends it as an against-the-grain pick. At $9.86, shares are down 12.4% since the beginning of the year, and recently have been bumping up against the 200-day moving average.

Now that Iraq is an independent country, the oil ministry has started putting its oil fields up for bid to foreign investors, as reported in The Wall Street Journal (subscription required).

Bidding started this week and is not going well according to oil executives. The reason is that Iraq is cutting its payout to the bone. Only one consortium, led by BP (NYSE: BP) and including China National Petroleum Company, ended up staying in the bidding and making a deal. All other oil executives walked away from the bidding.
