Major U.S. stock indexes flat on the last trading day of what could be the best month for stocks in four years as investors assessed consumer spending data and results from energy majors. The S&P consumer staples sector slipped after data showed U.S. consumer spending barely rose in September and the University of Michigan's index on consumer sentiment came in below expectations. The three major indexes have rallied about 9% in October, mostly driven by the Fed's decision to keep rates unchanged at its September meeting and largely positive third-quarter results.

Dow stocks mixed (15 in positive area, 15 in negative). Top looser -Pfizer Inc. (PFE, -2.27%). Top gainer - Chevron Corporation (CVX, +1.99%).

Most of S&P index sectors in positive area. Top gainer- Basic materials (+0,9%). Top looser - Financial (-0.6%).
