NEW YORK (Reuters) - U.S. stocks were little changed on Friday after the market's best two-day run in more than three years, with shares of Nike weighing on the Dow while energy shares led a modest advance on the benchmark S&P 500.
The S&P 500 index had climbed 4.5 percent over the previous two sessions, spurred by the U.S. Federal Reserve's commitment to take a "patient" approach toward raising interest rates, while signaling it was on track to boost rates in 2015. That provided clarity and relief to investors over the policy outlook, analysts said.

The benchmark stock index has risen more than 3 percent this week, putting the S&P on track for its best weekly performance in two months. It has erased nearly all the losses from the prior week, which were spurred by a sharp drop in oil prices.

At 1:16 p.m. EST, the Dow Jones industrial average <.DJI> fell 12.64 points, or 0.07 percent, to 17,765.51, the S&P 500 <.SPX> gained 2.58 points, or 0.13 percent, to 2,063.81 and the Nasdaq Composite <.IXIC> added 7.18 points, or 0.15 percent, to 4,755.57.
Quadruple witching - the expiration of stock options, index options, index futures and single-stock futures - may add to the day's volatility, along with the rebalancing of the S&P 500, which is scheduled to take effect after the close.
Shares of Red Hat
Advancing issues outnumbered declining ones on the NYSE by 1,780 to 1,258, for a 1.41-to-1 ratio; on the Nasdaq, 1,389 issues rose and 1,265 fell for a 1.10-to-1 ratio.
