The local stock market opened higher as top market cap Samsung Electronics continued to rise on hopes for earnings, but investors dumped part of share holdings to lock in recent gains ahead of the Federal Reserve's much awaited rate hike next week.

Also, market sentiment was dampened by a growing conflict between Seoul and Beijing over the installation of the missile defense battery.

"Investors are expected to take a wait and see mode until the Fed's meeting slated for next week," said Kim Sung-hwan, an analyst at Bookook Securities.
