Seoul shares end up

Seoul shares closed nearly 1 percent higher on Tuesday as sustained foreign buying lifted Samsung Electronics and other technology issues and as take-over talk rekindled interest in shares of local brokerages.
But investors remained cautious, holding off on sizeable equity investments on global security fears, an uncertain economic outlook and record high oil prices, analysts said.
"Persistent foreign buying brought some psychological stability to the market," said Kim Jung-hwan, a strategist at LG Investment Securities.
"Technology stocks and financials benefited the most from the foreign buying, but the market still remains vulnerable to external risks such as higher oil prices."
