Oct 6 (Reuters) - U.S. stocks were little changed in morning trading, with a surge in DuPont helping the Dow inch higher and a decline in health care stocks weighing on the Nasdaq.
The S&P was little changed after having gained 5.6 percent over the past five days, its best 5-day run since 2011.
DuPont rose 10.6 percent to $56.74 after it said CEO Ellen Kullman would step down. The stock gave the biggest boost to the S&P and the Dow, where it added nearly 36 points.
All three major U.S. indexes have gained since Friday when a weak U.S. jobs report led to expectations that the Federal Reserve would not raise interest rates this year, meaning the era of near-zero interest rates would continue.

Six of the ten major S&P sectors were up, with the material sector's 1.5 percent gain leading the advancers.
The health sector fell 0.86 percent, after having posted gains for five days in a row. The Nasdaq biotech index was down 1.8 percent, falling for the second straight day.
Crude oil prices rose more than 1 percent, adding to their gains from Monday and boosting the energy index by 1.3 percent.
