April 6 (Reuters) - U.S. stock index futures edged up on Thursday, a day after Wall Street saw its biggest reversal in 14 months following signals that the Federal Reserve could start unwinding its balance sheet this year.
* Investors also shied away from making big bets ahead of a potentially tense two-day meeting, starting Thursday, between President Donald Trump and his Chinese counterpart, Xi Jinping.

* Earnings of S&P 500 companies are expected to have risen 10.1 percent. The index is trading at about 18 times forward earnings estimates, above its long-term average of 15.
* U.S. stocks have risen on bets of fiscal stimulus, tax cuts and other pro-growth promises that Trump has made. However, recent setbacks in the new administration's efforts to push through its plans have led to some investors to question its ability to make good on its vows.
* On Wednesday, House of Representatives Speaker Paul Ryan said tax reforms would take longer to accomplish that the healthcare overhaul as the House, Senate and the White House were not on the same page over the policy.
* On Thursday, investors will keep an eye on a report that is likely to show jobless claims slipped to 250,000 last week from 258,000 the week before. The data is due at 8:30 a.m. ET (1230 GMT).
