U.S. stocks ended little changed on Friday, losing ground late after Federal Reserve Chair Janet Yellen's comments on the economy unnerved investors, Reuters reported. Financial shares finished up, giving the S&P 500 its biggest boost after stronger-than-expected bank results, but gave up most of their early gains. Healthcare shares led declines. Yellen, in a speech at a conference of policymakers and academics, laid out the deepening concern at the Fed that U.S. economic potential is slipping - and may need aggressive steps to rebuild it. Yellen did not address interest rates or immediate policy concerns directly. Traders have currently priced in a 67-percent chance of a rate hike in December.
