據韓媒報道，韓國15家金融機構因涉嫌在總額約76萬億韓元的國債拍賣中操縱投標價格，或將面臨公平交易委員會（FTC）的制裁。韓國公平交易委員會認定，這些金融機構事先串通國債投標利率，構成“嚴重違法行爲”，並警告稱最高可能處以15萬億韓元罰款。不過，金融投資行業對此提出反駁，認爲“將在政府制定的制度框架內開展的做市活動認定爲市場串通，是過度解讀”。韓國公平交易委員會6日表示，已向15家金融機構發送調查報告，並啓動制裁審議程序。根據公平交易委員會調查結果，上述15家金融機構在2020年1月至2023年6月約三年半時間內，在國債競爭性拍賣過程中交換信息，包括提前協調投標利率。一名公平交易委員會官員表示：“這並非簡單的慣例性溝通，而是涉及圍繞投標利率進行具體且頻繁的協議和信息交換。”該官員稱，調查人員認爲，這種串通行爲已經對國債市場產生了影響。

Huatai Securities says short-term consensus remains unsettled; the decisive window for a trend rebound in A-shares is late August, when mid‑year results, NVIDIA’s earnings and redemption flows during any rally could determine whether tech can sustain a new leg up. Medium‑term, evidence for a second‑derivative inflection in the AI cycle is still insufficient; portfolio focus should shift from 'investment scale' to 'revenue realization', narrowing into names with high earnings visibility and limited free‑float/valuation pressure. Preferred segments: cloud and platform providers, semiconductor equipment, PCB and optical modules.
