S&P 500前景:美股下跌,Nvidia受美國晶片出口限制拖累

美國旗幟與金融市場圖像

美國股市走勢:Nvidia重挫,拖累科技板塊

美國股市周三下挫,Nvidia成為領跌主角,原因是美國政府對中國實施新一輪晶片出口管制,令美中貿易戰再度升溫。美國商務部周二晚間宣布,Nvidia和AMD的AI晶片出口至中國必須獲得新牌照,令原本預計可為Nvidia帶來120至150億美元收入的H20晶片,現時無法在中國市場銷售,引發科技股全面拋售潮。

市場避險情緒升溫,黃金價格急升至創新高的每盎司3300美元。

雖然美國三月份零售銷售數據超預期,按月增長1.4%(預期為1.3%,前值0.2%),汽車及零件經銷商銷售按年大增8.8%,但貿易戰和關稅不確定性依然籠罩市場。這些數據涵蓋了特朗普4月2日公布新一輪報復性關稅前的情況,強勁表現或與消費者趕及「解放日」前搶購有關。

投資者現時焦點轉向聯儲局主席鮑威爾稍後發表的經濟前景講話。市場預期聯儲局五月減息25個基點的機會僅兩成,特朗普加徵關稅或令通脹居高不下,同時拖慢經濟增長。

主要指數及板塊表現

– 道瓊斯期貨跌0.4%至40210點
– 標普500期貨跌0.8%至5346點
– 納指期貨跌1.6%至18525點
– 歐洲FTSE跌0.3%,DAX跌0.17%

Nvidia股價大跌超過6%,公司預計因出口限制將承受55億美元損失。同行如AMD、Broadcom、Super Micro Computer亦因市場預期同樣面臨重擊而下跌。

Tesla下挫逾2%,有傳公司暫停從中國進口Cyber Cab及電動貨車零件,反映美中貿易戰升級的直接影響。

另一方面,聯合航空股價上升6.8%,因公司公佈本季預訂情況穩定,儘管關稅帶來經濟不確定性。

標普500技術分析

標普500指數自4月低位4800點回升,遇5500點阻力後回落。若要確認牛市重臨,買家需突破5500點並衝破下跌趨勢線。現時50天移動均線正下穿200天線,形成「死亡交叉」信號,賣家或將目標下移至5300點甚至5150點。

外匯市場動態:美元走弱,歐元英鎊受惠

美元徘徊於三年低位,難以吸引買盤。市場對經濟前景的疑慮及關稅陰霾蓋過零售銷售利好。歐元兌美元止跌回升,主要受惠於美元疲弱,雖然歐盟大部分貿易關稅即將實施。歐洲央行明天罕有議息,預料將減息25個基點。

英鎊兌美元升至1.33,創六個月新高,儘管英國CPI按年增長2.6%(預期2.7%,前值2.8%),低於預期,市場普遍預計英倫銀行五月減息。

油價受美中貿易談判憧憬支持

油價昨日平收後,今日升約1%,因市場憧憬美中或重啟貿易談判。不過,能源需求前景仍受壓,限制油價升幅。貿易戰降溫暫時減低下行風險,但不確定性依然高企。

國際能源署(IEA)及石油輸出國組織(OPEC)均下調2025年全球石油需求增長預測,特朗普關稅亦預期拖慢石油生產增速。2025年全球石油需求增長將創五年新低。

編輯評論:美中科技戰進入新階段,全球資本市場何去何從?

這次Nvidia及其同行遭遇美國出口限制,反映美中科技戰已經由口水戰升級至實質打擊,尤其針對AI、半導體這些未來產業命脈。對美國科技巨頭來說,短線損失明顯,但長遠來看,這或會迫使企業重新審視供應鏈和市場策略,甚至加速「去中國化」。

不過,這種「去中國化」未必能一帆風順。中國市場龐大,AI及高端晶片需求持續增長,長遠或促使中國加快自研技術,反而令美國企業失去關鍵市場,兩敗俱傷。對香港甚至亞洲區投資者來說,這場科技冷戰意味著全球資本流動和供應鏈格局將出現結構性變化,投資策略必須更靈活和國際化。

另一方面,美元弱勢和黃金創新高,顯示環球資金避險意識高漲。美國利率政策、通脹壓力與貿易戰博弈,已經成為全球金融市場的多重風險來源。油價方面,雖然貿易談判有望重啟,但需求增長放緩,能源市場前景仍不明朗。

總結來說,美中貿易與科技戰不單是兩國間的角力,更深遠地影響全球產業鏈、資本市場和地緣經濟格局。香港作為國際金融中心,面對這種新常態,既要洞察國際局勢,也要把握區內新機遇。投資者宜審慎評估風險,適時調整配置,才能在動盪中尋找新出路。
