June 8 (Reuters) - U.S. stocks were modestly lower in early trading on Monday as investors weighed the prospect of the Federal Reserve raising interest rates as soon as September, after Friday's strong jobs report.
While the Fed is broadly expected to raise rates this year, the timing of the move has kept the market on tenterhooks as the central bank studies data for signs of a healthier economy.
The stronger-than-expected jobs data for May and a pickup in wages were the latest signs of improved momentum in the economy, prompting expectations of a rate hike coming sooner rather than later.
Wall Street's top banks said they expect the Fed to begin raising rates in September, followed by another increase before the end of the year, according to a Reuters poll.
"I think we'll see a lot more back and forth for a while," said Scott Brown, chief economist at Raymond James in St. Petersburg, Florida.
"There are concerns that the Fed will be more aggressive regarding the timing of the hike and a steeper hike following the first one."
The dollar retreated after a report - later denied - that President Barack Obama had expressed concern over its strength after a year-long rally.
