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.

Although Toyota Motor Corp. (NYSE: TM) was first out of the gate with a gas/electric hybrid vehicle back in 1997 with the Prius, the holy grail for much of the consumer automotive industry has been a 100% electric vehicle that lasts a while on a charge, is big and roomy, and has a long range.

Oh, and it must remain comparable (read: affordable) in price to its fossil fuel cousins. The former GM's Chevy Volt project was a very good stab at this (who knows where that project is heading, though), but what about world automotive leader Toyota?

Quarterly earnings could be up year-over-year by the fourth quarter. A low threshold for improvement, as a result of last year's Q3 financial meltdown, could set the stage for the appearance of a recovery, but the ride from here to there will be a difficult one.

Data from Bloomberg and S&P suggests that profits for stocks comprising the S&P 500 Index may be down 21% next quarter. It's still a double-digit blow, but a better result than Q2's estimated 34% -- and far ahead of Q1's 60% year-over-year fall in profits. The driver of a recovery, however concealed by low expectations, is likely to be a combination of unemployment and consumer spending. Last month, we saw unemployment reach a 26-year high, putting obvious constraints on purchasing.

Ford (NYSE: F) is the last of the "Big" Three standing on its own two feet. Chrysler and General Motors (OTC: GMGMQ) are on crutches supplied by the federal government. While they're both still upright, those crutches are mighty expensive (the government will own 60% of GM when it emerges from bankruptcy).

Speaking of bankruptcy, Chrysler is already on the other side and now a partner with Fiat. That was perhaps the fastest legal action ever seen. Usually bankruptcy takes between 18 months to two years before a new company emerges.

I recently attended a Lakers' basketball playoff game and took notice of the fact that Toyota Motor Corp. (NYSE: TM) was a major sponsor advertising at Staples Staples Inc (NASDAQ: SPLS) Center. This, while our home grown car companies are all on the verge of collapse.

As we write stories on the depressed economy readers frequently comment about "buying American" as a theme that will help the greater good by keeping jobs and money in the United States.

This patriotic notion got me thinking about what would happen if we carried it further? Would we stop advertising and promotion of foreign products? Would we restrict discussion of foreign products in the media all together? Would we limit the production of foreign products here, even if they are providing jobs for Americans?

Every global automaker is facing sliding sales, employee layoffs and plant re-tooling in the midst of a massive and lasting shift in consumer buying habits (especially in the United States). Honda Motor Co. (NYSE: HMC) -- while not hurting as much as American domestic manufacturers -- has seen drops in year-over-year auto sales. Still, the Japanese automaker will be lowering purchasing incentives as it believes there is a recovery coming soon to its sales.

VW may have passed Toyota (NYSE: TM) as the world's No.1 car company just as Toyota passed GM (NYSE: GM) a year ago. Unfortunately, the companies all operate in an industry where being on the top of the pile does not matter much these days. It is probable that each of these firms loses money on the great majority of the cars they sell. To make matter worse, market share may be a weakness as the auto industry moves out of the recession.

It seems more and more likely that modest sized and nimble auto makers like BMW and Hyundai, who do not have to maintain factories in distant corners of the world and do not have to develop and market dozens of individual products, may hold an advantage in a fragmented car industry. The behemoths rely on their ability to maintain massive capital spending and their cost structures can do them nearly irreparable harm in a weak economy.
