US futures flat; S&P 500 off record

New York - US stock index futures were little changed on Tuesday, with investors finding few reasons to buy after a rally in the previous session that took the S&P 500 above 2,000 for the first time.

Equities have rallied lately, with both the Dow and S&P advancing in seven of the last 10 sessions, while the Nasdaq has climbed in eight of the last 10 trading days.

Nonetheless, further gains may be a challenge without positive catalysts and amid potential headwinds such as a reduction in Federal Reserve stimulus and a simmering conflict between Ukraine and Russia.

Dow Jones industrial average e-mini futures added 22 points and Nasdaq 100 e-mini futures added 6 points.

That appeared to continue Tuesday, with Achillion Pharmaceuticals up 6.1 percent to $11.44 (R122) before the opening bell.

Gilead Sciences Inc rose 0.6 percent to $108.13.

The recent fatal police shooting of an unarmed black teenager in Missouri has fuelled interest in the company's devices.

The stock was the Nasdaq's heaviest premarket mover.
