The S&P 500 was up 5.5 percent from its low on Oct. 15 and had its best weekly gain in nearly two years, boosted by solid corporate earnings reports.
News of the first case of Ebola diagnosed in New York City hit futures late on Thursday, but the markets shook off those concerns on Friday. A doctor being treated for Ebola in a New York City hospital is in stable condition, the city's health commissioner said, while the World Health Organization set out plans for speeding up development and deployment of experimental Ebola vaccines.
