Just read this recently at Los Angeles Times, on the 20th anniversary of worst one-day market crash in Wall Street, stocks tumbled Friday as the confidence that created record highs just a few days ago gave way to revived economic worries tied to housing troubles and a stubborn credit crunch.

The Dow Jones industrial average sank almost 367 points, or 2.6%. Last week, many investors surmised that the worst of the fallout from the sub-prime mortgage debacle was over.

But the Dow dropped every day this week as big banks posted billion-dollar mortgage-related losses and top government officials warned about the risks that the depressed home market posed for the overall economy.

And Friday, several large U.S. companies offered downbeat assessments of their business prospects, prompting investors to discard the notion that, despite signs of economic weakness in this country, big American firms could stay healthy by continuing to sell their goods to fast-growing emerging markets overseas.

Are we approaching another market crash? It is really amazing how stock market could just be an issue of psychological panic selling. Of course, this panic selling is caused by another bubble bursting!!
