[21日 ロイター] – 米国株式市場は主要3指数が急反発して取引を終えた。デンマーク自治領グリーンランドに関する合意の枠組みがまとまったと伝わり、米国が欧州諸国に新たな関税を課す可能性が回避されたことを受けた。
ニューヨーク株式市場の主要3指数は、21日、大幅に上昇した。ダウ工業株30種平均は、前日比399ドル高の2万9369ドルで取引を終え、週間では1.8%上昇した。ナズダック総合指数は、前日比119ポイント高の9095ドル、S&P500種平均は、前日比44ポイント高の3337ドルで終了。ダウ平均とS&P500種平均は、いずれも昨年12月19日以来の高値を更新。ナズダック総合指数も、昨年12月19日以来の大幅な上昇率となった。
トランプ米大統領は訪問先のスイスで北大西洋条約機構(NATO)のルッテ事務総長と会談後、「グリーンランド、北極圏全体に関する将来の合意の枠組みを構築した」と自身の交流サイト(SNS)に投稿。「この理解に基づき、2月1日に発効予定だった関税は発動しない」とした。 もっと見る
プラス圏で推移していた主要3指数は、投稿を受けて上げ幅を大きく拡大した。グレンミードの投資戦略・研究責任者ジェイソン・プライド氏は「誰がグリーンランドを領有するかが、経済面で直ちに何らかの影響を与えるとは思わない」とし、「経済への影響は誰もが互いに関税を課し始めた場合に生じる」と述べた。

It’s common for financial data providers to release preliminary or “provisional” figures, especially after market close. These are subject to revision as final data becomes available. Day-on-day discrepancies are also normal during this process.
* Current status (as of 2026/01/22 00:17:44): LSEG continues to be a leading financial data provider. The practise of releasing provisional data remains standard in the industry. No new data contradicts this.

* Current Status (as of 2026/01/22 00:17:44): The US stock market remains a primary global financial center. Data accuracy and the use of provisional figures are still standard practices. No new information contradicts this.
