NEW YORK (Reuters) -Stocks fell in choppy trade on Wednesday, as pessimism about the U.S. economy mounted after Intel Corp (INTC.O), the world's largest chip maker, posted earnings and a profit forecast that disappointed investors.

NEW YORK (Reuters) - Stocks tumbled on Wednesday, adding to the previous session's plunge, as recession concerns intensified after Intel Corp (INTC.O), the world's largest chip maker, gave quarterly earnings and a profit outlook that missed Wall Street estimates.

The government of Abu Dhabi gives the chip maker a cash infusion. The investment arm of the government of Abu Dhabi bought an 8.1% stake in Advanced Micro Devices Inc. for more than $600 million, breathing financial life into the struggling chip maker as it battles Intel Corp.

Its stock price falls 17% after news that research took a huge bite out of the bottom line. Broadcom Corp. executives have a vision of the Irvine chip maker eventually supplying all the brains and power in cellphones, but Wall Street wasn't waiting Wednesday for that to happen.
