Major U.S. stock-indexes lower on Friday, suggesting investors were wary of taking big positions into the weekend after days of tumultuous trading that featured both the market's worst day in four years and biggest two-day gain since the financial crisis. Even so, the three major U.S. indexes looked set to end the week higher after a brutal selloff early in the week sparked by worries about the health of the Chinese economy.

Most of all Dow stocks in negative area (23 of 30). Top looser - Wal-Mart Stores Inc. (WMT, -1.56%). Top gainer - Chevron Corporation (CVX, +2.77).

Almost all S&P index sectors in negative area. Top looser - Financial (-0.7%). Top gainer - Basic materials (+1,1%).
