Stocks closed at session highs Monday, logging their best one-day rally in almost two weeks, boosted by Ben Bernanke's earlier comments that the Fed may continue its easy monetary policy if the jobs market continues to show signs of weakness.

The CBOE Volatility Index, widely considered the best gauge of fear in the market, closed near 14.
All 10 S&P sectors ended firmly in positive territory, led by health care and techs.
“The market is feeling more comfortable that Bernanke is not going to pull the rug out from underneath them and that they can really trust the rally,” said Carol Pepper, the CEO of Pepper International.
Bernanke said the U.S. economy needs to grow more quicklyif it is to produce enough jobs to further bring down the unemployment rate, which currently sits at 8.3 percent.
"Further significant improvements in the unemployment rate will likely require a more-rapid expansion of production and demand from consumers and businesses, a process that can be supported by continued accommodative policies,'' Bernanke told a gathering of the National Association for Business Economics.

Gold prices surged nearly 2 percent, while the U.S. dollar tumbled against a basket of major currencies.
Still, Pepper said the Fed is likely to keep its policy unchanged at the next FOMC meeting and are unlikely to start another QE3 for at least another month.
Meanwhile, Pepper expects the market to rally “at least another 10 to 15 percent” by year-end based on strong fundamentals and improved market confidence, though she warned there will be some pullbacks along the way.
Health care stocks, one of the biggest underperformers of the broader market this year, propelled the market higher as the Supreme Court hears argumentson the 2-year old U.S. health care overhaul law.

Other health care stocks such as Edward Lifesciences and Medtronic also rallied.
Techs also fueled the gains, with Dell trading higher after Brean Murray added the firm to its "long-term conviction" list.
