Major U.S. stock-indezes slightly lower on Wednesday, after two days of gains, fueled by a rally in energy stocks, pushed the three main indexes to within touching distance of their record highs. A report showing the private sector added more jobs than expected last month gave investors some optimism about the health of the labor market ahead of Friday's nonfarm payrolls data.

Dow stocks mixed (16 in negative area, 14 in positive area). Top looser - UnitedHealth Group Incorporated (UNH, -2.35%). Top gainer - Caterpillar Inc. (CAT, +0.83%).

S&P index sectors also mixed. Top gainer Industrial goods (+0,3%). Top looser - Conglomerates (-1.0%).
