After a respite yesterday, the market resumed a more than weeklong decline, giving back gains from the previous session's rally. Investors are selling on worries about earnings, mistrust of corporate accounting and international conflicts between India and Pakistan and Israel and Palestine.

The Dow Jones industrial average closed down 172.16, or 1.8 percent, at 9,624.64, according to preliminary calculations. The loss easily wiped out the Dow's 108.96-point gain yesterday, when all of the market's major indicators finished higher for the first time in nearly two weeks.

The broader market also fell sharply. The Nasdaq composite index dropped 40.38, or 2.5 percent, to 1,554.88, losing all of its 17.14 advance from yesterday.

The Standard & Poor's 500 index fell 20.75, or 2.0 percent, to 1,029.15, erasing yesterday's gain of 9.21.

Analysts said the market's persistent selling is no surprise because earnings remain depressed, jeopardizing the recovery investors had hoped would happen in the second half of 2002.

Fears of improper bookkeeping, involving Tyco and several other companies in the wake of Enron's collapse, and worries about tensions overseas also have given investors little reason to buy. The market was anxious about a terrorism update by President Bush, scheduled to be broadcast in the evening.

"There is just nobody buying. ... You still have the same problems in the Middle East, the terrorist scares, a downgrade of Intel and semiconductors. There just isn't any good news right now," said Barry Berman, head trader for Robert W. Baird & Co. in Milwaukee.

Intel fell $1.18 to $27 after Merrill Lynch lowered its near-term rating on the stock to "neutral" from "strong buy." Investors were also reluctant to take chances on Intel ahead of its mid-quarter business update due out later in the day.

Also downgraded by Merrill, Texas Instruments fell 75 cents to $27.69, and Triquint Semiconductor sank 91 cents to $7.47.

Tyco plunged nearly 16 percent, down $2.70 at $14.60, on concerns that former chief executive Dennis Kozlowski abused company funds. New York prosecutors are investigating whether Kozlowski tapped company accounts to buy his $18 million New York apartment or whether he got interest-free loans from Tyco to buy artwork. The Securities and Exchange Commission has also opened an investigation, according to a report in The Wall Street Journal.

Earnings are the biggest factor weighing on stocks, Kaltbaum said.

"To get things going, you have to beat earnings and beat them good," Kaltbaum said.

Meeting already-lowered expectations isn't enough to inspire investors to buy and hold onto shares, Kaltbaum said, who pointed to recent trading in Oracle.

Oracle fell 51 cents to $8.15, losing some of its 84-cent gain yesterday when chief executive Larry Ellison said the company would meet fourth-quarter expectations for earnings of 12 cents a share.
