Major U.S. stock-indexes slightly fell on Monday as a fall in oil prices hit materials stocks, offsetting a rise in healthcare shares. Crude prices were slightly lower as hopes that top oil producers would reach an agreement to help tackle a stubborn global glut faded. Investors have also been skittish following U.S. Federal Reserve Chair Janet Yellen's comments last week urging caution on raising rates, which were in contrast with remarks made by some policymakers supporting more aggressive stance on rates.

Most of Dow stocks in negative area (19 of 30). Top looser - NIKE, Inc. (NKE, -2,92%). Top gainer - Pfizer Inc. (PFE, +2,15%).

Most of S&P sectors in negative area. Top looser - Industrial goods (-0,9%). Top gainer - Healthcare (+1,3%).
