(Reuters) - Republican Donald Trump, who defeated heavily favored Democratic rival Hillary Clinton in Tuesday's U.S. presidential election, has said he won't approve AT&T Inc's (>> AT&T Inc.) $85 billion acquisition of Time Warner Inc (>> Time Warner Inc) because the deal represented "too much power in the hands of too few."

Trump's comments are not seen as indicative of his overall policy on M&A, although uncertainty about his policies could temporarily stall merger activity, analysts said.

"The talk around being against the Time Warner-AT&T merger was mostly campaign rhetoric, so I don't think there is going to be a dramatic shift in the approach," said Mark Heppenstall, chief investment officer at Penn Mutual Asset Management, who expected Trump to be "generally friendly toward corporate America."

A senior Wall Street banker, who asked not to be named, said "a lot of deals will hit the pause button for a bit until we get some clarity on whether President Trump will moderate or be as disruptive as some expect."
