U.S. stocks rallied to begin what has historically been the strongest month of the year for global equities, breaking out of a lull that held the Standard & Poor’s 500 Index to its narrowest monthly move in six years as investors await December monetary policy decisions.

The benchmark index added less than 0.1 percent in November as signs of a strengthening economy offset concerns of an imminent interest-rate increase. The gauge is up 2.1 percent this year, headed toward its smallest move in four years. Health-care shares rebounded Tuesday to lead gains after erasing a November advance yesterday in the month’s final session.

The S&P 500 added 1.1 percent to 2,102.49 at 4 p.m. in New York, and closed at its highest level since Nov. 3.
