Nov 19 (Reuters) - Wall Street wobbled on Thursday as healthcare stocks ended a three-day rally after UnitedHealth cut its profit forecast, offsetting gains in Intel and other technology stocks.
UnitedHealth fell 5.2 percent, making the health insurer the biggest drag on the Dow. The company's profit warning sent shares of peers Anthem and Aetna down more than 6 percent.

Pfizer dropped 3.4 percent after reports that the company's talks to buy Allergan and redomicile in Ireland were in final stages. Allergan was down 2.6 percent.
Intel Corp jumped 3.6 percent after boosting its annual dividend. The chipmaker and Apple, up 1.3 percent, added more upward pressure to the S&P 500 than any other stocks.
Mobile payments company Square soared 45 percent in its highly anticipated market debut, while Tinder-owner Match Group's shares popped 20 percent on their first trading day.

U.S. interest rates futures implied a 72-percent chance of a liftoff next month, up from 64 percent on Tuesday.
Investors are increasingly looking to what the Fed might do in 2016 and many are becoming more cautious, said David Carter, chief investment officer at Lenox Wealth Advisors in New York.
