Nov 10 (Reuters) - U.S. stock index futures were trading lower on Friday on concerns that a delay in corporate tax cut till 2019 may stall the stock market rally that was powered in part by Donald Trump’s election win.
* A Republican tax-cut bill could be delayed after Senate Republicans unveiled a plan that would push a corporate rate cuts to 20 percent by a year and provide small-business owners with a deduction rather than a special business rate.
* The Senate Republicans version of the bill differs markedly on corporate, business and individual tax cuts from legislation detailed by their counterparts in the House of Representatives.
* The S&P 500 index has surged more than 20 percent since the election of President Donald Trump, fueled by his promises to cut corporate taxes and other business-friendly measures.
* All three major indexes were on track to end lower for the week, with the S&P and the Dow on track to post weekly losses after eight straight weeks of gains.
* The S&P 500 is trading at 18 times expected earnings, expensive compared with its 10-year average of 14.3, according to Thomson Reuters Datastream. Cutting corporate taxes would boost earnings and make stocks relatively less expensive.
* With third-quarter earnings winding down and stocks still trading at record levels, investors are also looking to book profits.
* Earnings for the quarter are expected to have climbed 8 percent, compared with expectations of a 5.9 percent rise at the start of October, according to Thomson Reuters I/B/E/S.
* Shares of Nvidia were up 4.7 percent after the chipmaker’s revenue forecast for the current quarter topped estimates.
* Hertz Global Holdings jumped 9.5 percent as the car rental company reported a better-than-expected net profit.
* Nordstrom fell 1.1 percent after its quarterly same-store sales came in below expectations.
