韩国股市周三明显走强,AI 芯片相关个股领涨。市场交易主线集中在两点:SK 海力士宣布大规模股票回购,以及美国长期国债收益率回落,缓解了高估值科技股面临的融资压力。

SK海力士宣布大额回购

SK 海力士披露,将启动规模约 288 亿美元的股票回购计划。回购消息直接提振了公司股价,也带动韩国半导体板块整体走高。

报道提到,三星电子当日也大涨近 9%。这意味着,单靠 SK 海力士的回购消息,并不足以解释整个板块的同步上行,市场更关注外部利率环境变化对 AI 交易的推动。

美国长债收益率回落

美国财政部表示,将把部分用于支持流动性的长期国债回购操作规模,从每次 20 亿美元提高到至少 40 亿美元。消息公布后,美国长期国债收益率下行。

据路透社数据,30 年期美债收益率下跌约 10 个基点,降至约 5.19%。对科技股而言,长期利率回落通常意味着融资条件改善,也会提升市场对高资本开支行业的风险偏好。

AI基础设施预期获得支撑

三星电子和 SK 海力士都是 AI 产业链中的关键供应商,尤其是在先进存储和高带宽内存芯片领域。随着利率压力缓解,市场对大型云服务商持续投入 AI 基础设施的信心有所回升。

此前,AI 存储器交易已受到估值偏高和借贷成本上升的双重压制。KB 证券策略师李恩泽曾警告,如果美国 10 年期国债收益率维持在 5% 至 5.3% 区间,数据中心融资吸引力可能下降,进而影响 AI 投资周期。

从盘面表现看,这次上涨反映出市场仍在围绕利率与资本开支预期重新定价 AI 板块。对芯片股而言,资金当前更关注融资环境是否继续改善,以及大型科技公司能否维持 AI 投资强度。
