The S & P 500 index in the US stock market rose for a close of eight weeks on Friday as the U.S. senate tax reform disclosed on Thursday disagreed with the House tax reform proposal, prompting investors to take profits.

There are few signs of compromise so far, and the head of the House drafting tax reform bill opposes a Senate Republican proposal that will raise taxes on some of the middle class.

"Everyone is watching how the representatives of both senate and senate will make adjustments to their tax reform," said Nobuhiko Kuramochi, chief strategist at Mizuho Securities.

"There is no surprise in the controversy, but it is a tough time for the market," he said.
