SEOUL, Oct. 12 (Yonhap) -- Seoul shares plunged more than 3 percent Monday, extending their losing streak to a fourth session, as a massive sell-off in technology stocks fueled by inflation concerns weighed on the market amid elevated oil prices.

The Korean won rose against the U.S. dollar.

After opening 0.07 percent lower, the benchmark Korea Composite Stock Price Index (KOSPI) extended losses to close down 241.69 points, or 3.65 percent, at 6,384.24.

Trade volume was moderate at 313 million shares worth 21.33 trillion won (US$16 billion), with decliners outnumbering advancers 717 to 166.

Institutions and foreigners sold a net 110.65 billion won and 2.02 trillion won worth of stocks, respectively, while individuals bought a net 1.47 trillion won.

"The KOSPI plunged amid rebalancing of semiconductor-focused exchange-traded funds (ETFs) and concerns that Samsung Electronics and SK hynix may have completed their treasury stock purchases," Lim Seung-mi, an analyst at Hana Securities Co., said in her research note.

Oil prices rose amid escalating tensions in the Middle East following renewed Houthi attacks on Saudi Arabia's main airport over the weekend.

A broader regional conflict could further disrupt energy supplies, adding to inflationary pressures and complicating the Federal Reserve's efforts to bring inflation under control, analysts said.

In Seoul, tech stocks led the decline.

Market behemoth Samsung Electronics fell 4.39 percent to 250,500 won, and its chipmaking rival SK hynix declined 4.52 percent to 1.6 million won.

Defense giant Hanwha Aerospace dropped 3.25 percent to 862,000 won, and top carmaker Hyundai Motor shed 1.39 percent to 320,000 won.

Among gainers, shipping firm HMM rose 4.81 percent to 21,800 won and dominant tobacco company KT&G climbed 1.58 percent to 180,200 won.

The Korean won was quoted at 1,335.1 won against the U.S. dollar as of 3:30 p.m., compared to 1,342.8 won from the previous stock trading session's close.

首尔，10月12日（韩联社）——受通胀担忧引发的科技股大规模抛售以及高企的油价拖累，首尔股市周一暴跌逾3%，连续第四个交易日下跌。

韩元对美元汇率上涨。

韩国综合股价指数（KOSPI）开盘下跌0.07%，随后跌幅扩大，最终收跌241.69点，跌幅3.65%，报6384.24点。

交易量适中，为 3.13 亿股，价值 21.33 万亿韩元（160 亿美元），下跌股票数量超过上涨股票数量，比例为 717 比 166。

机构投资者和外国投资者分别净卖出价值 1106.5 亿韩元和 2.02 万亿韩元的股票，而个人投资者净买入价值 1.47 万亿韩元的股票。

“由于半导体类交易所交易基金（ETF）的再平衡，以及市场担忧三星电子和SK海力士可能已经完成其库存股购买，韩国综合股价指数（KOSPI）大幅下跌，”韩亚证券分析师林承美在其研究报告中表示。

周末胡塞武装再次袭击沙特阿拉伯主要机场，导致中东紧张局势升级，油价因此上涨。

分析人士表示，更广泛的地区冲突可能会进一步扰乱能源供应，加剧通胀压力，并使美联储控制通胀的努力更加复杂。

在首尔，科技股领跌。

市场巨头三星电子股价下跌 4.39%，至 250,500 韩元；其芯片制造竞争对手 SK 海力士股价下跌 4.52%，至 160 万韩元。

国防巨头韩华航空航天公司股价下跌3.25%至862,000韩元，顶级汽车制造商现代汽车股价下跌1.39%至320,000韩元。

截至下午 3:30，韩元兑美元汇率为 1,335.1 韩元，而前一交易日收盘价为 1,342.8 韩元。
