But Wall Street may struggle to build on these gains given the doubts about the retail spending level in the important festive season sales that started Friday night, our time, and the crucial US unemployment figures Friday.
But interest rate cuts around the world will be a major positive.
Wall Street ended the holiday-shortened week in the black, ending a mid-month losing streak as investors were encouraged by the government's bailout of Citigroup and then the moves by the Fed and US Treasury to provide more than $US600 billion to support mortgage and credit card and other consumer markets. It will basically buy and finance home loans, car loans and credit cards for a while.
The Standard & Poor's 500 Index had its best week since at least 1980 - rising 12%.
That reversed the previous week, when the S&P booked its lowest close since 1997. For the four-day week, the Dow Jones industrial average rose 9.7% and Nasdaq jumped 10.9%.
Still, big losses among financial and automaker shares made November among the worst months for Wall Street since the October 1987 stock market crash. The Dow fell 5.3%, the S&P 500 lost a considerable 7.5% and the Nasdaq lost 10.8%.
The yield on the US Treasury 10-year bond fell 0.31% to 2.93%. It touched 2.90% on Friday, the lowest since the Federal Reserve's daily records on the note began in 1962, and since 1958 on a monthly basis.
The 30-year bond's yield tumbled 0.27% to 3.44%. It touched 3.43% on Friday, the lowest since regular sales of the security started in 1977.
At these levels the huge US bond market is signalling an intense recession next year and no inflation.
In fact the chances of deflation in the middle months of 2009 are very real as this year's huge oil price rises from March to July fall out of comparisons.
Australian markets could be a touch firmer Monday after a 15 point rise on the Share Price Index Saturday morning. The Aussie dollar closed around 65.50 USc.

In Europe the FTSEurofirst 300 index of top European shares closed 1.1% higher on Friday for a 13% gain over the week. It fell 7% for the month, the ninth month in a row it has lost ground.
