SEOUL, Oct. 7 (Yonhap) -- South Korean stocks dipped by nearly 2 percent on Wednesday to extend their losses for a second consecutive session, led by declines in technology shares, amid concerns over rising bond yields that have climbed to multidecade highs. The Korean won strengthened against the U.S. dollar.

The benchmark Korea Composite Stock Price Index (KOSPI) extended its losses to close down 137.49 points, or 1.98 percent, at 6,803.90.

After opening 1.11 percent lower, the KOSPI briefly turned higher but eventually closed lower as investors remained concerned about elevated bond yields.

Local shares fell despite overnight gains on Wall Street.

Global oil prices fell on easing supply concerns, while bond yields retreated from their multidecade highs.

The Dow Jones Industrial Average rose 0.49 percent, while the tech-heavy Nasdaq composite gained 0.45 percent to reach a record high.

Trade volume was light at 256.76 million shares worth 19.69 trillion won (US$14.68 billion), with decliners outnumbering advancers 525 to 332.

Foreigners and institutions sold a net 2.59 trillion won and 672.7 billion, respectively, while individuals bought a net 2.56 trillion won.

"The KOSPI came under renewed pressure amid rising international oil prices and U.S. Treasury yields," Lee Kyung-min, an analyst at Daishin Securities, said. "Investors also took a wait-and-see approach ahead of Samsung Electronics' preliminary earnings report, prompting both foreign and institutional investors to become net sellers."

Market heavyweights ended lower.

Market bellwether Samsung Electronics lost 1.29 percent to 268,500 won after opening higher ahead of earnings guidance on Thursday, while chip giant SK hynix went down 2.82 percent to 1.72 million won.

SK Square, the parent company of SK hynix, decreased 1.64 percent to 1.14 million won, while Samsung Electro-Mechanics, an electronics component affiliate of Samsung Electronics, shed 4.24 percent to 1.6 million won.

The Korean won was quoted at 1,340.4 won against the U.S. dollar as of 3:30 p.m., compared to 1,343.6 won from the previous stock trading session's close.

Bond prices, which move inversely to yields, closed lower. The yield on three-year Treasurys added 2.8 basis points to 3,961 and the return on the benchmark five-year government bonds went up 1.7 basis points to 4.134.

首尔，10月7日（韩联社）——受债券收益率攀升至数十年来高位的担忧影响，韩国股市周三下跌近2%，连续第二个交易日走低，科技股领跌。韩元兑美元汇率走强。

韩国综合股价指数（KOSPI）跌幅扩大，收盘下跌137.49点，跌幅1.98%，报6803.90点。

韩国综合股价指数(KOSPI)开盘下跌1.11%，随后短暂走高，但最终收跌，因为投资者仍然担心债券收益率过高。

尽管隔夜华尔街股市上涨，但本地股市却下跌。

由于供应担忧缓解，全球油价下跌，同时债券收益率也从数十年来的高位回落。

道琼斯工业平均指数上涨0.49%，而以科技股为主的纳斯达克综合指数上涨0.45%，创下历史新高。

交易量清淡，为 2.5676 亿股，成交额为 19.69 万亿韩元（146.8 亿美元），下跌股票数量超过上涨股票数量，比例为 525 比 332。

外国人和机构分别净卖出 2.59 万亿韩元和 6727 亿韩元，而个人净买入 2.56 万亿韩元。

大信证券分析师李京敏表示：“受国际油价和美国国债收益率上涨的影响，韩国综合股价指数（KOSPI）再次承压。此外，在三星电子发布初步财报前，投资者也采取了观望态度，导致外国投资者和机构投资者均成为净卖出方。”

市场巨头收盘下跌。

市场风向标三星电子周四开盘走高，但随后下跌1.29%，至268,500韩元，此前该公司发布了盈利预期；芯片巨头SK海力士下跌2.82%，至172万韩元。

SK海力士的母公司SK Square股价下跌1.64%至114万韩元，而三星电子的电子元件子公司三星电机股价下跌4.24%至160万韩元。

截至下午 3:30，韩元兑美元汇率为 1340.4 韩元，而前一交易日收盘价为 1343.6 韩元。

债券价格与收益率呈反向走势，最终收跌。三年期美国国债收益率上涨2.8个基点至3961%，五年期基准国债收益率上涨1.7个基点至4.134%。
