4:25 pm : A drop by the dollar brought buyers in from the sidelines after stocks had fallen for three straight sessions. Early support helped the S&P 500 come within just a couple of points of a new 2009 high, but resistance at current highs left stocks to gradually pare gains for the remainder of the session.

The Dollar Index erased its gains from the previous two sessions with a 0.6% fall. Indian Prime Minister Singh offered support for the greenback, but comments by Chicago Fed President Evans and St. Louis Fed President Bullard stirred selling pressure against the currency. Evans made it known that he thinks near-zero interest rates will remain well into 2010, while Bullard wants to keep the Fed's Mortgage-Backed Securities program active beyond the first quarter of 2010.

There weren't many market-moving headlines for participants to digest this session, though the latest home sales figures proved pleasing. Existing home sales for October made a sharp 10.1% month-over-month spike, which lifted sales to an annualized rate of 6.10 million units. The consensus had called for a 2.3% monthly increase to an annual rate of 5.70 million units. The stronger-than-expected increase in sales took supply down to 7.0 months, the lowest since February 2007.

All 10 major sectors were able to put together solid gains as a result of broad-based support. Telecom settled with the best gains; it advanced 2.6% after AT&T (T 26.78, +0.76) received positive coverage by Barron's.
