NEW YORK (TheStreet) -- The Federal Reserve brought some much-needed holiday cheer midweek, triggering a three-day rally which saw major indexes jump more than 3% over the past five sessions. The market gains were broad and plentiful after Fed Chair Janet Yellen pledged patience in raising interest rates next year. The S&P 500 added 0.45%, mere points below its all-time closing high of 2,075 reached early December.
