Wall St falls on GE

NEW YORK (Reuters) - Stocks fell for the second day on Thursday after Standard & Poor's threatened to strip General Electric of its 'AAA' credit rating and slumping oil prices crippled energy shares.

* General Electric shares tumbled 6 percent and ranked among the top drags on the Dow after S&P said there is at least a 1-in-3 chance that it will cut the company's credit rating from the top "AAA" tier in the next two years.

* Chevron Corp and Exxon Mobil were the biggest drags on the Dow as oil fell another $4 to settle near $36 a barrel on growing fears of falling demand.

* The Dow Jones industrial average <.DJI> tumbled 219.19 points, or 2.48 percent, at 8,605.15. The Standard & Poor's 500 Index <.SPX> dropped 19.05 points, or 2.11 percent, at 885.37. The Nasdaq Composite Index <.IXIC> slipped 26.94 points, or 1.71 percent, at 1,552.37.
