SEOUL, Nov 6 (Reuters) - Seoul shares rose on Friday, with foreign investors chasing auto parts maker Hyundai Mobis (012330.KS) and KB Financial Group, while brokerage stocks bounced back on hopes stock markets might have bottomed out.

The advance was held back by concerns about the won's KRW= rise to a two-week high, with recently outperforming food and domestic sales-oriented stocks such as snack maker Nong Shim (004370.KS) under pressure on uncertainty over the market direction.

"At the current valuation of 10 price-to-earnings ratio, the market is neither expensive nor cheap in historical terms," said Park Seung-young, a market analyst at IBK Investment & Securities.

"But with no change to the earnings consensus, uncertainties remain over the macroeconomic conditions after the fourth quarter and onward."

The Korea Composite Stock Price Index (KOSPI) was 1.29 percent higher at 1,572.23 points by 0126 GMT.

By Thursday's finish, the index had shed 10 percent of its value since touching a 15-month high in late September.

Volume sank to a 14-month low on Thursday, with 204 million shares changing hands, less than half the level when the KOSPI hit its 15-month peak.

Shares in Hyundai Mobis rose 4.6 percent to 160,000 won, clawing back some of their heavy losses the previous day.

KB Financial Group (105560.KS), parent of top domestic bank Kookmin, added 2.8 percent, while brokerage Daewoo Securities (006800.KS) leapt 4.9 percent.

Foreign investors picked up a net 55 billion won worth of shares, largely offsetting local institutions' net selling of 15 billion won and institutional investors' sales of a net 44 billion won.

SK Energy (096770.KS), South Korea's largest crude refiner, jumped 5.1 percent on persistent expectations about its lithium-ion battery output.
