Major U.S. stock-indexes kicked off the last month of the year on a positive note as investors await data and policy decisions by central banks.

U.S. auto sales are expected to rise above 18 million vehicles on an annualized basis for November, continuing the pace for record sales in 2015. Investors are keeping an eye on data for clues regarding the health of the U.S. economy that might enable the Federal Reserve to raise interest rates for the first time in nearly a decade. The main data this week is the November employment report, which is expected to show that the economy added 200,000 jobs during the month. Analysts say a strong report virtually guarantees a rate rise this month.

Most of Dow stocks in positive area (27 of 30). Top looser - Caterpillar Inc. (CAT, -1.07%). Top gainer - The Boeing Company (BA. +2.30%).

Most of S&P index sectors also in positive area. Top looser - Conglomerates (-0.2%). Top gainer - Technology (+1,0%).
