Sept 20 (Reuters) - U.S. stocks opened marginally higher on Friday as an interest rate cut by China's central bank and signs of co-operation on trade between the world's two largest economies allayed concerns about a slowdown in global growth.
The Dow Jones Industrial Average rose 7.39 points, or 0.03%, at the open to 27,102.18.
The S&P 500 opened higher by 1.63 points, or 0.05%, at 3,008.42. The Nasdaq Composite gained 2.00 points, or 0.02%, to 8,184.88 at the opening bell. (Reporting by Ambar Warrick in Bengaluru; Editing by Anil D'Silva)
