They sound nervous at the casino this time.

Stock prices around the world continued to plunge on Friday, threatening to end one of the longest bull runs in the history of the United States stock market.

A searing six-year rally in United States stocks had advanced into the summer months, shrugging off challenges like the dispute over Greece’s debt. But in the last two weeks, world markets tumbled as investors grew increasingly concerned about developments in China, which unexpectedly devalued its currency last week, and the outlook for the economies of other large developing countries.

As the selling gathered steam Friday afternoon, some benchmark indexes were at or near 10 percent below their recent peaks — a “correction” in Wall Street parlance. “This is likely going to go down as the first meaningful correction in four years,” said David Rosenberg, an economist and strategist at Gluskin Sheff.

If there's another recession and oil stays as low as it is, and we're at the end of our post-Katrina spending boom, how will we manage to "buck the trend" this time?
