Dow tumbles 200 as selloff accelerates

NEW YORK (CNNMoney.com) -- The stock selloff accelerated Tuesday afternoon on worries about a possible credit crunch and disappointing profit forecasts from Home Depot and Wal-Mart Stores, sending the Dow industrials tumbling 200 points.

The 30-share Dow (down 172.90 to 13,063.63, Charts) sank as much as 200 in afternoon trading, though it quickly rebounded and was off about 170 points, or 1.3 percent, with just over an hour left in the session. The broader S&P 500 (down 21.21 to 1,431.71, Charts) index slid 1.4 percent while the tech-fueled Nasdaq Composite (down 33.98 to 2,508.26, Charts) index sank 1.5 percent.

Stocks opened in mixed territory Tuesday with the Dow and the S&P 500 feeling the impact from retailers and the Nasdaq managing modest gains, thanks to a mild core inflation number in the morning's Producer Price Index (PPI).

However, by midmorning the tone had turned negative, with all three major gauges seeing declines.

In addition to retail sector woes, financial stocks were hit once again on worries about the credit crisis. Additionally, a second look at the PPI, which showed a bigger-than-expected jump on the overall reading may have raised concerns about Wednesday's more closely-watched Consumer Price index (CPI), said Fred Dickson, chief market strategist at D.A. Davidson & Co.

"Today, bad news is outweighing the good news," Dickson said. "PPI was hotter than expected, Wal-Mart's outlook countered Home Depot's better earnings and there are residual concerns relating to the mortgage market."

Stocks have been battered on and off over the last few months on concerns about tightening of credit after a period of great liquidity. Investors have also been sorting through the impact of the slumping housing market, including the collapse of the subprime mortgage market - loans made to consumers with less than ideal credit.

Among the factors reviving some of this uneasiness Tuesday: media reports that Sentinel, a money market mutual fund firm for commodities, has asked regulators for permission to halt client withdrawals.

Additionally, Countrywide Financial (down $2.06 to $24.56, Charts, Fortune 500), the leading U.S. mortgage lender, slipped after the company said that foreclosures and delinquencies rose in July to their highest level in several years.

Dragging on the Dow was a disappointing profit report and forecast from Wal-Mart Stores (down $2.39 to $43.78, Charts, Fortune 500). Shares of the world's largest retailer fell 5 percent.

Fellow Dow retailer Home Depot (down $1.30 to $33.94, Charts, Fortune 500) slipped 2.8 percent after reporting higher-than-expected quarterly earnings on weaker-than-expected quarterly sales. The home improvement retailer also reiterated that its per-share profit will dip as much as 18 percent this year.

Other blue chip losers included McDonald's (down $1.03 to $47.68, Charts, Fortune 500), Boeing (down $2.08 to $97.97, Charts, Fortune 500), Hewlett-Packard (down $1.28 to $47.15, Charts, Fortune 500) and financial stocks AIG (down $1.45 to $63.33, Charts, Fortune 500) and Citigroup (down $0.93 to $45.61, Charts, Fortune 500).

A variety of other financial stocks slumped as well, lowering the Amex Broker/Dealer index by over 2 percent.

Shares of EMC (down $0.35 to $18.70, Charts, Fortune 500) fell in active New York Stock Exchange trade as investors took a 'sell the news' approach to the debut of its spinoff VMware. Software maker VMware (up $23.64 to $52.64, Charts) surged 73 percent Tuesday morning in its debut as a public company.

And Mattel (down $0.74 to $22.83, Charts, Fortune 500) shares slipped after the toy maker said it's expanding its toy recall to include over 9 million additional toys manufactured in China, as a result of lead paint and loose magnet risks.

Market breadth was negative. On the New York Stock Exchange, losers topped winners by more than four to one on volume of 1.08 billion shares. On the Nasdaq, decliners beat advancers two to one on volume of 1.23 billion shares.

On the economic front, the Producer Price index (PPI), a measure of inflation at the wholesale level, rose 0.6 percent in July, topping forecasts. However, prices excluding volatile food and energy rose just 0.1 percent, short of expectations.

Separately, the U.S. trade gap fell unexpectedly in June, with strong imports countering the impact of higher energy prices.

Treasury prices erased early losses, turning higher, lowering the benchmark 10-year note yield to 4.72 percent from 4.76 percent late Monday. Treasury prices and yields move in opposite directions.

In currency trading, the dollar rose versus the euro and the yen.

U.S. light crude oil for September delivery rose 58 cents to $72.20 a barrel on the New York Mercantile Exchange.

COMEX gold for December delivery fell 41.10 to $679.80 an ounce.
