Dec 20 (Reuters) - U.S. stocks edged lower on Wednesday as the long-awaited tax bill was all but assured of becoming law, allowing investors to take a breather after a month-long rally in anticipation of the largest overhaul of the U.S. tax code in 30 years.

The bill was approved on a 51-48 vote, but was sent back to the House of Representatives for a re-vote by the Senate due to a procedural snag. It is expected to be passed. urn:newsml:reuters.com:*:nL1N1OK0AU

The proposed changes include cutting the corporate tax rate to 21 percent from 35 percent from Jan. 1, which is expected to boost company earnings and lead to higher dividends and stock buybacks for investors. urn:newsml:reuters.com:*:nL1N1OJ21J

The S&P 500 has climbed about 4.5 percent since mid-November when the House passed its tax overhaul bill, led by a rally in sectors such as transport and banks that are expected to benefit the most from lower taxes.

"We rallied a lot on sort of a non-event and I think there is a little bit of head scratching about what's really new that we should be rallying on," said said JJ Kinahan, chief market strategist at TD Ameritrade in Chicago.

"There is no news to take us higher in terms of stocks, part of it could be rotation out of bonds and maybe some nibbling at stocks that perhaps people think will perform well in 2018."

At 10:58 a.m. ET (1558 GMT), the Dow Jones Industrial Average .DJI was down 8.01 points, or 0.03 percent, at 24,746.74 and the S&P 500 .SPX was down 3.07 points, or 0.11 percent, at 2,678.4.

The Nasdaq Composite .IXIC was down 21.43 points, or 0.31 percent, at 6,942.42.

The Dow Jones Transport Index .DJT rose 0.69 percent crossing 10,600 points for the first time ever, helped by a surge in FedEx.
