美股禁晶片令YTL Power跌3.6% AI股市震盪加劇




YTL Power 股價急跌3.6%,美國禁售Nvidia晶片拖累AI相關股份全線受壓

YTL Power International Bhd(YTL電力國際)今早股價一度大跌3.6%,中午報RM3.97,主要受美國加強對Nvidia(輝達)AI晶片出口限制的市場情緒拖累,這一消息震盪全球市場,連帶馬來西亞一眾AI概念股亦受壓。

今早YTL Power以RM4.00開盤,盤中曾低見RM3.81,之後略為回升至中午RM3.97。成交量急增至超過2,240萬股,反映投資者情緒緊張。相比昨日收市價RM4.12,跌幅明顯。

YTL Power過去一年一直是馬股的明星股,憑藉其在AI數據中心電力需求的增長,以及與Nvidia生態圈夥伴的合作,股價表現強勁。不過,美國政府即將進一步收緊AI晶片出口限制,禁止Nvidia部分半導體出口至中東及其他非盟友市場,令AI供應鏈增長預期出現急劇調整。

市場觀察人士指出,YTL Power今次被拋售,反映市場憂慮美國對Nvidia的限制措施升級,可能間接拖慢該集團在新興市場大舉擴張AI數據中心的步伐。

一名持有馬來西亞大型基建股的基金經理表示:「YTL Power一直被視為高Beta的AI代理股。只要Nvidia業務出現任何受壓跡象——即使只是在相鄰市場——都會波及本地市場情緒。」

雖然今日股價下挫,但YTL Power今年以來仍累升逾80%,背後是強勁盈利動力和投資者對數碼基建的熱烈關注。不過,分析員預計,若美國進一步擴大出口禁令,或中國採取反制技術限制,估值或需重新評估。

美國新一輪禁令已衝擊全球半導體板塊,拖累多個科技股指數下跌,包括馬股的F4GBM指數中午跌0.94%。另一隻AI概念股NationGate Holdings Bhd早段亦重挫7.9%。

分析師警告,地緣政治風險為AI供應鏈和基建規劃帶來不確定性,YTL Power等股份短期內波動或會持續。

編輯評論:AI熱潮下的高風險博弈,馬股投資者要小心「美國變數」

這宗YTL Power急挫事件,正好突顯了當前AI主題投資的高波動和高風險特質。YTL Power過去一年因數據中心和AI主題而被瘋炒,但這種「高Beta」投資邏輯,往往一遇到政策或地緣政治風吹草動,股價就會劇烈震盪。美國針對Nvidia的出口禁令,表面上只限於部分地區,但其實已足以令整個AI供應鏈神經緊繃,間接波及馬來西亞這類新興市場的相關股份。

值得注意的是,這種「AI概念」的溢價,建立在對未來增長的樂觀預期。一旦外部環境轉變(如美國再收緊出口、或中美科技戰升級),這些預期隨時會被市場重新定價。YTL Power雖然基本面仍有增長,但現時股價已大幅反映未來數據中心和AI需求的樂觀情景,容錯空間其實極窄。

對香港投資者來說,這一事件亦有啟示——科技股、尤其是AI主題股,無論在美國、中國還是東南亞,現時都已高度「政策敏感」。在全球科技供應鏈日益分裂的背景下,任何一方出手都可能引發連鎖反應。投資者要有心理準備,AI熱潮背後的地緣政治風險或許比想像中更大。

未來,YTL Power及其他AI供應鏈相關股份的走勢,很大程度要看美國、甚至中國的政策「風向」。短期內,這些股份的波幅只會愈來愈大,投資者宜審慎部署、嚴控風險,不要單純追逐主題炒作而忽略了潛在的「黑天鵝」風險。

Use the original face exactly as it is, without changing a details. A female model with sharp features, defined cheekbones, and intense, direct eye contact (though eyes are slightly in shadow from the hat).
• Aesthetic: Vintage fashion, Pin-up, 1950s/1960s style, high-glamour, summer resort wear.
• Lighting: Bright, harsh sunlight creating high contrast and crisp shadows. The light should perfectly illuminate the skin and the vibrant colors of the dress.
• Color Palette: Dominated by vibrant yellow, crisp white, and bold red, accented by deep black.
Specific Outfit & Details:
• Dress: A bright yellow halter-neck sundress with a classic white polka-dot pattern. It has a fitted, sweetheart neckline or bustier-style top that enhances the silhouette.
• Accessories:
• A very large, wide-brimmed sun hat in crisp white (or light straw/fabric) that casts a shadow over the upper face.
• A matching yellow polka-dot scarf tied closely around the neck (like an ascot or choker-style).
• Large, striking black statement earrings (circular, drop, or bead style).
• Bold red lipstick is a key feature, contrasting sharply with the yellow and white.
Technical/Camera Details:
• Shot: Close-up or medium-close-up portrait, focusing on the torso, neckline, face, and hat.
• Depth of Field: Shallow (low f-stop), with the model in sharp focus and the background slightly blurred (bokeh).
• Background: Out-of-focus, suggesting a bright outdoor location, with abstract shapes of boats/yachts (white and red accents visible) in a marina setting. 一隻在香港茶餐廳喝奶茶的貓 Create a photorealistic movie-poster image for Zootopia 2. The scene shows a young Asian man and an oversized black shirt standing inside a crowded, dimly lit cinema. He’s flanked by Judy Hopps in full police uniform and Nick Wilde, both rendered in their official Disney CGI style. Capture the shot from a low angle so the characters feel larger than life. The cinema screen behind them is glowing with an intense action scene from the film. Let the light from the screen spill across their faces and clothing to create dramatic high contrast. The environment should feel alive with background silhouettes, soft haze, and the warm ambience of a packed theatre. Style the composition like an official Disney promotional poster: epic layout, sharp detail, high resolution, balanced framing, and clean edges. The man and the cinema should be fully photorealistic, while Judy and Nick retain their signature animated look.
At the bottom, include:
• The Disney logo
• The title ZOOTOPIA 2 in bold green and white
• The release line ONLY IN THEATERS NOVEMBER 26 Poster tone: cinematic, polished, high-end theatrical marketing.
