Is 9/15 the new Black Monday. Or not?

"Today's drop is tough to take, but it was no Black Monday," Kirk Shinkle, a senior editor at U.S. News and World Report, blogs tonight.

But many other news outlets are saying that 9/15 is the new Black Monday.

"Decliners swamped advancers by 19-to-1 on the NYSE," reports Vincent Mao of Investors Business Daily. "This was worse than Black Monday 1987. On that day NYSE decliners to advancers were 15.75 to 1."

The Dow Jones Industrial Average plummeted over 500 points today, closing just below 11,000 points and suffering its worst loss since 2002.

The loss was partially a response to Lehman Brothers filing for bankruptcy protection. The 158-year-old investment bank is the fourth-largest in the U.S., and its $639 billion filing is the largest in U.S. history.

In Canada, the S&P/TSX Composite Index closed down 515.55 points, at 12,254.03 – the largest fall since January.
