NEW YORK (CNNMoney) -- U.S. stocks plunged on Tuesday as fears about a weak U.S. economy were enflamed after investors got another disappointing economic report - this time on consumer spending.
The selloff was so broad and so deep it pushed the S&P 500 into negative territory for the year and bond yields to their lowest levels in nine months.
"Now that we have solved the debt ceiling issue the market has moved onto the other data, which has taken a significant turn for the worse," said Ryan Detrick, senior technical strategist with Schaeffer's Investment Research.
This was the eighth-straight day of declines for the Dow -- a losing streak not seen since October 2008, when the financial system was in the depths of the crisis. The Dow has fallen roughly 6.7% since the sell-off began on July 22.
The S&P 500 () lost 33 points, or 2.6%, to 1,254, and the Nasdaq Composite ( ) dropped 75 points, or 2.8%, to 2,669.
The S&P 500 broke through several key technical resistance points as the session wore on, including the index's closely-watched 200-day moving average. The S&P closed below the 1,258-point mark -- putting it in negative territory for the year.
As the sell off accelerated, investors quickly shifted gears and fled to traditional safe-havens: bonds and gold.
Yields on the 10-year Treasury note declined to their lowest levels since early November, hitting 2.61% after nearly falling below the 2.6% level earlier. Prices and yields move in opposite direction.
Meanwhile, gold prices surged, hitting a record high of $1,644.50 an ounce.
Stocks started the day lower after a weak report on personal income and spending showed Americans cut spending for the first time in 20 months in June.
"There are still a lot of fears about how slowly the economy is growing," said Hamed Khorsand, analyst at BWF Financial.
Economy: Monday's dour manufacturing report came on the heels of last week's GDP report, that showed the U.S. economy grew at an annualized pace of just 1.3% in the second quarter. More disturbingly, the first-quarter reading was revised down to 0.4%.
Investors will get a number of fresh data points on the economy this week, with the most important coming Friday in the July jobs report.
