— The Dow lost 1,874.19 points, or 18.2 percent, during the week. Its dismal performance outdid the week that ended July 22, 1933, which saw a 17 percent drop — and back then, during the Great Depression, there were six trading days in a week.

— The Dow has fallen for eight straight sessions — the longest losing streak since the eight days of declines following the Sept. 11, 2001, terror attacks, when the blue chips lost 1,038.12, or 10.8 percent.

— It's been the worst run for the Dow since the nearly two-year bear market that ended in December 1974 when the Dow lost 45 percent.

— Since hitting their record highs a year ago, the Dow has lost 5,713 points, or 40.3 percent, while the S&P 500 is off 665.90 points, or 42.5 percent.

Beyond the Dow, broader stock indicators were mixed Friday.

The S&P 500 index fell 10.70 or 1.18 percent, to 899.22. The 18.2 percent drop for the week was the S&P's steepest decline since the week ending May 21, 1933; its worst loss was in 1929, when it fell 19.9 percent. The index lost 200.01 points for the week.

The Nasdaq composite index rose 4.39, or 0.27 percent, to 1,649.51. For the week, the Nasdaq lost 297.88, or 15.3 percent.

The Russell 2000 rose 23.28, or 4.66 percent, to 522.48. For the week, the Russell fell 96.92, or 15.64 percent.

Decliners led advancers 2-to-1 on the New York Stock Exhange, where consolidated volume came to a record 11.2 billion shares, compared with 8.14 billion traded Thursday.

Most major central banks around the world slashed interest rates this week after continuing problems in the credit market triggered concerns that banks will run out of money. Analysts have described the mood on trading floors this week as panicked at times, with investors bailing out of investments on fears there is no end in sight to the financial carnage.

A stream of selling forced exchanges in Austria, Russia and Indonesia to suspend trading, and those that remained opened were hammered. The rout in Australian markets caused traders there to call it "Black Friday."

European stocks sank Friday, with Britain's FTSE-100 falling 8.85 percent, German's DAX declining 7.01 percent, and France's CAC-40 ending down 7.73 percent. In Asia, the collapse of Japan's Yamato Life Insurance caused already nervous investors to pull even more money out of the market — the Nikkei 225 fell 9.6 percent.

An index considered to be Wall Street's fear gauge reached record highs on Friday in another sign of massive investor anxiety. The Chicago Board Options Exchange Volatility Index, known as the VIX, rose to an all-time intraday high of 76.94 Friday. The VIX, which usually trades under 50, tracks options activity for the companies that make up the S&P 500.
