South Korea's stock markets gained 0.63 percent on Tuesday extending its winning-streak to a fourth day as uncertainty over the U.S. Fed's interest rate policy eased.

The local currency rose against the greenback.

The benchmark Korea Composite Stock Price Index advanced 12.59 points to 2,016.29. Trading volume was moderate at 406.9 million shares worth 4.27 trillion won ($3.7 billion), with gainers outpacing losers 434 to 368.
  

Analysts said the eased uncertainties surrounding the U.S. rate policy lent support to the growth, although a further rise was limited due to lack of market-moving events.
  

"Investors' consensus is that the scheduled rate hike of the U.S. this year will not lead to a panic in the market. Thus, the KOSPI gained ground," said Lee Young-gon, an analyst at Hana Financial Investment.
  

The South Korean stock market, however, is expected to remain in a tight range amid lingering concerns over the Chinese economy, along with the lack of other market-moving events, analysts added.
  

Foreigners sold a net 184.8 billion won, and individuals also offloaded a net 126.3 billion won. Institutions, however, scooped up a net 233.4 billion won.  
  

Tech shares traded mixed, with top market cap Samsung Electronics rising 1.33 percent to 1,299,000 won while global chipmaker SK hynix shed 1.47 percent to 30,200 won. LG Electronics edged up 1.08 percent to 56,200 won.
  
SK, the holding firm of South Korea's No. 3 conglomerate, shot up 2.99 percent to 258,000 won after it has decided to take over OCI Materials as part of an effort to bolster the semiconductor material business.

  
Construction firms also remained in positive terrain. Hyundai Engineering & Construction added 4.42 percent to 34,250 won, and Daewoo Engineering & Construction climbed 1.54 percent to 6,580 won. Daelim Industrial added 1.37 percent to 74,000 won.

Mobile carriers were also winners, with No. 1 SK Telecom rising 0.22 percent to 233,000 won and KT advancing 0.85 percent to 29,800 won. LG Uplus climbed 3.79 percent to 10,950 won.
  

The local currency ended at 1,153.80 won against the greenback, up 4.7 won from Monday's close. (Yonhap)
