Down day, down week on Wall Street
Weaker-than-expected results from Dow component and a sharp drop in a consumer sentiment measure drag down stocks.
NEW YORK (CNNMoney.com) -- Stocks tanked Friday after General Electric's weaker-than-expected profit report exacerbated fears about how badly the economic slowdown is going to impact corporate earnings.

"GE was definitely the main driver today," said John Davidson, president and CEO at PartnerRe Asset Management. "It's pretty heavily followed, it has a lot of diverse businesses and the report was really a surprise."
GE (GE, Fortune 500), often seen as a proxy for the economy due to the breadth of its businesses, reported lower first-quarter sales and earnings that missed estimates as the sluggishness plaguing the nation hurt its financial services business. The company, a Dow component, also cut its second-quarter and full-year 2008 profit forecast. Shares fell nearly 13%.
"We're in a period where we need enough time to pass so all the negatives that are being held over our heads can be exposed," said James King, chief investment officer at National Penn Investors Trust.
"The most difficult time for the market is when you know something is wrong but you don't know how bad it's going to get," he said. "Something like GE brings all of that to a head."
The company's poor results played into fears that the weakness in the economy is going to have a worse impact on corporations than has been anticipated.
"My guess is that earnings forecasts for 2008 are still pretty high relative to the economic reality," Davidson said. "Until there is a realization of that, stocks are going to continue to get knocked around."
Next week brings a big batch of financial sector earnings, with Merrill Lynch (MER, Fortune 500) and Citigroup (C, Fortune 500) among the companies due to report abysmal results. (Full story).
