NEW YORK, Oct 10 (Reuters) - U.S. stocks slid on Friday, as panicked investors unwound risky bets in a global sell-off on fears that tighter credit would spawn world recession.
Volume was heavy across the board and trading was volatile, with all three major U.S. stock indexes gyrating widely between steep losses and gains since the open.
Shares of Morgan Stanley <MS.N>, an investment bank that recently converted to a bank holding company, lost 36 percent to the lowest in over a decade after ratings agency Moody's warned it might cut the company's long-term debt ratings and those of rival Goldman Sachs <GS.N>.
At one point, the Dow Jones industrial average slid as much as 8 percent to break below 8,000 for the first time since April 1, 2003, and then briefly turned positive, along with the broader market as expectations that the sell-off might be overdone collided with fears of more losses.
"There's no confidence -- there's an atom or two of confidence returning," said Steve Goldman, market strategist at Weeden & Co. in Greenwich, Connecticut.
"We need confidence to return into the banking system and, hopefully, we can sort our way through this. There's still the unknown. It's just at this point bargain hunting."
The Dow Jones industrial average <
> was down 457.26 points, or 5.33 percent, at 8,121.93. The Standard & Poor's 500 Index <.SPX> was down 52.29 points, or 5.75 percent, at 857.63. The Nasdaq Composite Index < > was down 69.93 points, or 4.25 percent, at 1,575.19.Uncertainty about what authorities would do next to contain fallout from the credit turmoil contributed to the fear, driving the Chicago Board Options Exchange Volatility Index <.VIX> up 14 percent to another intraday record high above 73.
Morgan Stanley shares slumped to $7.94 on the New York Stock Exchange.
Goldman Sachs shares fell 23 percent to $78.10 on the New York Stock Exchange. Investors worry that a cut in ratings would further complicate the companies' ability to raise capital.
Shares of energy companies dragged on the broader market as oil prices sunk to a fresh 12-month low below $79 a barrel on signs that a faltering global economy will crimp demand for crude.
Shares of Exxon Mobil <XOM.N> were a top drag on the Dow, sliding more than 13 percent to $58.82 on the NYSE, as shares of Chevron <CVX.N> plummeted more than 11 percent to $56.88.
The S&P energy index <.GSPE> was down 12.5 percent, while the financial index <.GSPF> declined 3.2 percent.
A pullback in the cost for banks to borrow overnight dollars from, or among, each other tempered some market anxiety but the cost to borrow dollars over three months shot higher again, indicating credit markets effectively remain jammed.
In Asia Japan's Nikkei <
> tumbled 9.6 percent, while in Europe major indexes traded down more than 7 percent.On the bright side, shares of General Motors Corp <GM.N> climbed almost 5 percent to $4.99 after the company said bankruptcy was not an option that the car maker was considering as it grapples with "unprecedented challenges related to uncertainty in the financial market."
In Asia Japan's Nikkei <
> tumbled 9.6 percent, while in Europe, major indexes slid more more than 7 percent.U.S. front-month <CLc1> plunged over 8 percent to as low as $78.61, a fresh 12-month low, on the New York Mercantile Exchange.
