(Reuters) – U.S. stocks rose on Friday, pushing the Nasdaq to a 15-year high and helping the S&P 500 snap a three-week string of losses, following a pullback in the dollar, upbeat results from Nike and further biotech gains.

Largely behind this week’s gains was a statement from the Federal Reserve on Wednesday which signaled a less aggressive approach to raising interest rates than investors had expected.

“The Federal Reserve’s created a situation where there’s very little alternative to equities, so the path of least resistance for stocks will be up for a period of time,” said Robert Lutts, president, chief investment officer at Cabot Money Management in Salem, Massachusetts.

The Dow Jones industrial average rose 168.62 points, or 0.94%, to 18,127.65, and the S&P 500 gained 18.79 points, or 0.9%, to 2,108.06. The Nasdaq Composite added 34.04 points, or 0.68%, to 5,026.42, a 15-year high.
