WASHINGTON (REUTERS) -Stocks in the United States were little changed on Thursday amid a flood of quarterly earnings reports, while investors assessed President Donald Trump's tax reform plan.

The one-page plan, unveiled on Wednesday, proposed deep tax cuts for many businesses, but offered no detail on how it would be paid for without increasing the deficit.

US stocks snapped a two-day rally to end lower on Wednesday after the plan was unveiled. The prospects of hefty tax cuts have been a major driver of the post-election rally since November. "Yesterday, you saw some selling but it didn't develop into an outright heavy pressure day," said Robert Pavlik, chief market strategist at Boston Private Wealth.
