The Nasdaq composite and Standard & Poor's 500 indexes hit new five-year lows as the stock market endured a third straight day of heavy selling fed by bookkeeping scandals and poor prospects for earnings growth. Analysts said investors simply are too downtrodden to buy stocks, even after nearly eight weeks of selling have driven prices lower.

"This market has completely broken the spirit of investors," said Al Mirman, strategist at V Finance in Sarasota, Fla. "It is going to take a good year for investors' confidence to be reinstated."

The Dow plunged 282.59, or 3.1 percent, to 8,813.50, after falling 283.41 over the previous two sessions.

The Dow last closed below 9,000 on Oct. 2 when it stood at 8,950.59 as it was still recovering from its post-Sept. 11 losses. Before the terror attacks, the Dow had not had a lower finish since Dec. 16, 1998, when it stood at 8,790.60.

Today's loss was the Dow's biggest one-day decline since Sept. 20, when it fell 382.92.

The market's broader indicators also dropped. The S&P sank 32.36, or 3.4 percent, to 920.47, following its two-day loss of 36.20. The S&P last finished lower on Nov. 13 1997, when it stood at 916.66.

The Nasdaq fell 35.11, or 2.5 percent, to 1,346.01, having lost 67.24 over Monday and Tuesday. The Nasdaq last closed lower on May 19, 1997, when it was at 1,341.24.

Analysts said investors see virtually no reason to buy stocks now, and that they will continue to hold off until earnings show decided progress and companies improve the accuracy of the results they release.

"We're getting into (second-quarter) earnings season and more than ever, investors are looking for numbers they can trust," said Thomas F. Lydon Jr., president of Global Trends Investments in Newport Beach, Calif. "The pressure is on for corporations to give as accurate numbers as possible."

While Wednesday didn't see a new accounting fiasco, there was reason to question the strength and pace of a business recovery.

Blue chips, for example, were hurt by General Motors, which slid $3.53 to $47.61, and Ford, down $1.12 at $13.99, after Banc of America downgraded the stocks to "market perform" from "buy."

The investment firm's move left many investors feeling that there are few, if any, safe havens in the market. Losses spilled across sectors.

Philip Morris fell $1.52 to $45.17, Honeywell sank $1.31 to $33.53, and American Express tumbled $1.33 to $34.83.

And, Merck dropped $2.18 to $43.57 after announcing yesterday it was postponing for the third time in two weeks the initial public offering of its Medco unit.

Airline stocks closed at or near their lows that followed the terror attacks. Delta fell 52 cents to $17.75.

Today's big drop added to nearly two months of stunning declines. The Nasdaq has plunged nearly 400 points, or almost 223 percent, since May 17, the last time the market's major indexes ended a week with gains.

Since then, the Dow has fallen more than 1,500 points, or 15 percent, and the S&P has lost about 190 points, or almost 17 percent.

After a string of accounting debacles and more than two years of declines on Wall Street, Lydon said: "Confidence is so low that the average investor is saying, `I am fine keeping (my money) in a money market account at 1.5 percent. And when I see the worst is over, maybe I'll think about putting more money in the stock market."

However, there were some gainers today. Cisco Systems rose 37 cents to $13.51, and Extreme Networks advanced 60 cents to $9.93, after Merrill Lynch raised its near-term rating on the stocks to "strong buy" from "buy."

Declining issues outnumbered advancers 3 to 1 on the New York Stock Exchange. Volume was relatively heavy at 1.77 billion shares, compared with 1.35 billion yesterday.

The Russell 2000 index, which tracks smaller company stocks, fell 9.47, or 2.2 percent, to 419.78.

Overseas, markets were lower with Japan's Nikkei stock average finishing down 1.9 percent. In Europe,France's CAC-40 sank 4.3 percent, Britain's FTSE 100 fell 2.7 percent, and Germany's DAX index dropped 4.1 percent.
