Major U.S. stock-indexes decreased on Tuesday amid uncertainty surrounding the U.S. presidential election and tepid construction spending data. Construction spending in September unexpectedly fell, which could lead to a mild downward revision to the third-quarter economic growth estimate. Another set of data showed that while U.S. factory activity increased for the second straight month in October, a gauge of new orders slipped.

Most of Dow stocks in negative area (21 of 30). Top gainer - Chevron Corporation (CVX, +1.58%). Top loser - Pfizer Inc. (PFE, -1.88%).

Almost all S&P sectors also in negative area. Top gainer - Conglomerates (+0.4%). Top loser - Utilities (-1.2%).
