  .KS11
   was down 0.1 percent at 2,000.61 points as of 0215 GMT after touching an intraday low of 1,990.72, the weakest level since May 27.     Samsung Everland Inc said on Tuesday it will seek an IPO, a widely anticipated move seen as the next step in Samsung Group's restructuring and the transfer of control to the next generation of the owner Lee family.

       "Samsung Everland's IPO plan is good news for its affiliates, with investors increasing portfolio weighting of Samsung related shares while dumping the rest," said Hyundai Securities analyst Bae Sung-young.         Samsung Electronics Co Ltd

   and Samsung SDI Co Ltd  
  006400.KS
   rose 1.8 percent and 4.3 percent, respectively. KCC Corp  
  002380.KS
  , which has a 17 percent stake in Samsung Everland, jumped 8.2 percent.     The Samsung Everland news prompted some investors to adjust their portfolios.     "The market is digesting the portfolio switching and some investors are opting to stay in the sidelines before the upcoming market closures," added Bae.     South Korean financial markets will be closed on Wednesday and Friday due to elections and Memorial Day, respectively.     Foreign investors offloaded a net 97.8 billion won ($95.51 million) worth of KOSPI shares near mid-session, and looked set to snap a 15-day buying streak.     Foreigners have brought in 3 trillion won worth of capital into the main bourse during their streak.     Steelmaker POSCO

   eased slightly against the dollar on outflows from the stock market and as the greenback gained versus a basket of currencies on upbeat U.S. factory activity growth in May. But the demand for the won by exporters for settlements kept the won's weakness in check.     U.S. manufacturing activity accelerated in May and construction spending rose for a third straight month in April, suggesting economic growth was regaining steam in the second quarter.
