* Hyundai Mobis falls more than 5 percent
* Samsung Elec slides despite Q1 profit
* Foreigners sell for 11th session

SEOUL, April 26 South Korean shares eased on Friday as investors took profits on a rally driven by better-than-expected earnings results that took the benchmark index to a three-week high a day earlier.
Market paricipants said market sentiment remained positive, however, with Kia Motors lending support after the automaker reported better-than-forecast earnings and said it expects this quarter to be stronger.
"The market is generally seen heading up, but there's a little resistance at this level. That could be broken by better data out of China and the United States next week," Kim Yong-gu, an analyst at Samsung Securities.
The Korea Composite Stock Price Index (KOSPI) closed down 0.4 percent at 1,944.56 points but gained 2 percent on the week.
Foreign investors sold a net 118 billion won ($106.09 million) worth of KOSPI shares, an eleventh straight day of selling, spurred by weakness in the yen that makes rival Japanese exporters more competitive and a slower growth outlook for South Korea's economy compared to other emerging markets.
Decliners included auto parts supplier Hyundai Mobis which shed 5 percent after its quarterly operating profit slid 11.7 percent from the same period a year earlier.
Market bellwether Samsung Electronics slipped 0.5 percent despite posting a sixth quarter of profit growth.
Overall, 428 shares advanced while 369 declined.
The KOSPI 200 benchmark of core stocks closed down 0.6 percent, while the junior KOSDAQ edged 1 percent higher.
