SEOUL, Oct. 14 (Yonhap) -- South Korean stocks fell for the sixth consecutive session Wednesday on persisting concerns over excessive spending on artificial intelligence (AI) as investors remained cautious ahead of U.S. inflation data. The Korean won gained against the U.S. dollar.

After choppy trading, the benchmark Korea Composite Stock Price Index (KOSPI) lost 26.54 points, or 0.44 percent, to 6,008.81.

The KOSPI has dropped since Tuesday last week, including a 5.46 percent plunge the previous day.

After opening 0.44 percent higher, the index rose 2.57 percent around 9:34 a.m. following New York Fed President John Williams' media interview that he saw no need for further monetary tightening next year.

However, the gains were erased following Dutch tech giant ASML's lower-than-expected sales outlook.

ASML, which provides chip-manufacturing machines to major chipmakers, including Samsung Electronics, reported strong earnings for the third quarter, but its revised 2026 sales outlook failed to meet market expectations, considering a yearly 84 percent surge in its stock price.

"The KOSPI erased all of its gains after ASML's earnings report," Seo Sang-young, a senior analyst at Mirae Asset Securities, said. "Investors are also awaiting U.S. consumer prices data later in the day."

首尔，10月14日（韩联社）——由于投资者在等待美国通胀数据之际仍保持谨慎，对人工智能（AI）领域过度支出的担忧持续存在，韩国股市周三连续第六个交易日下跌。韩元兑美元汇率走强。

经过一番震荡交易，韩国综合股价指数（KOSPI）下跌26.54点，跌幅0.44%，收于6008.81点。

韩国综合股价指数（KOSPI）自上周二以来持续下跌，其中前一天暴跌5.46%。

该指数开盘上涨 0.44%，上午 9 点 34 分左右上涨 2.57%，此前纽约联储主席约翰·威廉姆斯在接受媒体采访时表示，他认为明年没有必要进一步收紧货币政策。

然而，由于荷兰科技巨头 ASML 的销售预期低于预期，这些涨幅被抹去。

为包括三星电子在内的主要芯片制造商提供芯片制造设备的ASML公布了第三季度强劲的盈利情况，但考虑到其股价全年上涨84%，其修订后的2026年销售预期未能达到市场预期。

“ASML发布财报后，韩国综合股价指数（KOSPI）抹去了所有涨幅，”未来资产证券高级分析师徐相永表示。“投资者也在等待当天晚些时候公布的美国消费者价格数据。”
