美中貿易緊張芯片股急挫Nvidia跌4%




Nvidia及其他晶片股因中美貿易緊張下挫

Nvidia, Other Chip Stocks Slide Amid Worries About US-China Trade Tensions

中美貿易陰霾再現,Nvidia領跌半導體板塊

Nvidia(美股代號:NVDA)以及其他多隻半導體股份,於星期五因市場憂慮中美貿易關係惡化而顯著下挫。

Nvidia股價在當日盤中跌近4%。同時,AMD(Advanced Micro Devices)、Broadcom、Micron Technology及Applied Materials等晶片製造商亦錄得跌幅,PHLX半導體指數(SOX)下跌約3%。

Nvidia的合作夥伴,包括伺服器生產商Super Micro Computer(SMCI),亦難逃跌市,股價同樣受壓。

特朗普放話中美協議「完全違反」,市場信心受挫

美國前總統特朗普週五公開表示,中國「完全違反了與我們的協議」,令市場對中美兩國早前短暫緩和後,能否達成更長遠協議的希望再次受挫。

與此同時,據彭博社報道,特朗普計劃擴大美國企業與中國有受制裁企業關聯的公司進行交易時的許可要求。

AI規管政策反覆,半導體業前景添變數

早前,拜登政府曾推出AI擴散規則,進一步限制美國AI硬件出口至更多國家,但本月初特朗普政府決定撤回該規則,並表示將以新規取而代之。當時,花旗及德意志銀行分析師警告,新限制或較拜登時期更嚴厲。

Nvidia行政總裁黃仁勳於週三的業績電話會議上表示,特朗普撤回拜登時期的規則是好事,但同時批評美國政府其他針對中國的銷售限制措施,認為「保護中國晶片製造商免受美國競爭,只會令他們在海外更強,削弱美國本身的地位。」

Nvidia因新出口限制,於本財政年度首季就向中國出口H20晶片而錄得45億美元撥備,並預計本季將因收入損失再承受80億美元打擊。

編輯評論:科技冷戰下的晶片角力,誰是終極輸家?

這次Nvidia及半導體板塊的集體下挫,絕不僅僅是一次普通的市場波動,而是中美科技冷戰下的又一次警鐘。晶片產業早已不是單純的商業競爭,而是國家安全、全球產業鏈主導權的較量。美國對中國的限制愈收愈緊,表面上是保護本土產業,實則亦可能令中國企業加速自立自強,反向推動國產替代與技術突破。

值得注意的是,Nvidia CEO黃仁勳的言論頗具警世意味——貿易壁壘短期內或許能阻擋對手,但長遠來看,卻可能削弱美國在全球科技領導地位。美國此舉會否最終變成「自斷手腳」?還是能夠有效壓制中國科技崛起?這場晶片戰爭,輸贏或許要等十年後才見分曉。

對香港及亞洲投資者而言,這類地緣政治風險已成為科技股不可忽視的變數。未來半導體產業鏈的重組、去美化趨勢,甚至AI新規的反覆,對整個行業的估值與增長都構成深遠衝擊。投資者宜密切留意政策走向,避免單一押注,並思考如何在中美科技新冷戰中尋找屬於自己的「安全島」。

最後,這波晶片股下跌,更提醒我們:科技發展從來不是純粹的技術問題,而是國際博弈下的權力遊戲。未來誰能主導AI、半導體等關鍵科技,誰就可能主導世界新秩序。這場比拼,才剛剛開始。

Prompt:
Use my image in Ultra-realistic, hyper-detailed, 8K cinematic portrait of a young stylish man, using the uploaded image for exact face and hairstyle.
Outfit: An oversized red knit sweater with white hearts, exactly as described in the prompt.
Pose: A hyper-realistic close-up portrait with a messy, cropped framing showing only the boy holding the book. His left hand rests on the wooden table and covers part of his cheek, with a subtle smile on his lips. His other hand holds the book titled "Something I Never Told You" with the word "YOU" written in pink, exactly as
described in the prompt. Background: Not specified. Replace the words in the bottom by ‘tantamount Deco’ Base Setup
keep 100 percent facial information adherence of the attached image and turn her into a girl standing beneath autumn leaves outside a traditional wooden structure in a live action photograph or movie still, wearing a complex suggestive outfit that harmonizes with the warm fall tones.

Shot and Camera
Three quarter shot at slightly low height, framing her off center to the right so the yellow leaves and carved wooden panels dominate the left. Maintain the intimate close framing and vertical orientation feel of the reference.

Identity and Pose
Preserve her age read, build, silhouette, hairstyle length, and skin tone. She leans lightly against the doorframe, one hand grazing a hanging leaf, her posture relaxed and candid, 8k Photorealistic and hyper realistic.

Lighting and Environment
Soft warm daylight filters through the leaves, casting dappled highlights on her hair and outfit. Ground her feet on aged wooden flooring with natural grain, faint scuffs, and subtle contact shadows.

Masking and Constraints
Change only wardrobe and placement while keeping lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same. Absolutely no added text, no CGI look, no plastic skin, no floating feet, with consistent perspective and correct contact shadows.
