Nvidia反彈力強 AI投資黃金時代?




Nvidia股價強勢反彈,AI熱潮與地緣局勢緩和推動科技巨頭再度加碼

Nvidia總部標誌

經歷數月低迷之後,Nvidia(輝達)股份終於重拾升勢。隨著市場對大型科技公司投資減慢的疑慮消退、美中貿易緊張局勢有所緩和,以及新一批晶片買家浮現,Nvidia再次成為焦點。

AI基建投資不減,Nvidia受惠最大

上星期Nvidia股價急升,並有望錄得一年來最佳單月表現。這波升勢源於美國總統特朗普中東之行期間,Nvidia簽下多份長期銷售協議。此前,美中兩國亦達成關稅暫停協議,加上剛過去的業績季,Nvidia最大客戶在人工智能(AI)基建上的資本開支依然積極,鞏固了Nvidia在AI晶片領域的主導地位。

Nvidia股價自四月低位反彈超過四成,距離一月二十四日(即DeepSeek推出R1模型,市場憂慮廉價AI發展會衝擊銷售、導致科技股大跌的前一日)收市價僅差不足百分之六。

Brave Eagle Wealth Management首席投資總監Robert Ruggirello指出:「這一季顯示,超大規模雲端公司(hyperscaler)持續上調資本開支預算,而Nvidia始終是最大受益者。大家都想趁派對結束前下車,但我看不到派對會這麼快完。」他形容AI投資現時只不過是「九局棒球比賽的第二局」。

技術走勢強勁,市值超越蘋果

自本月初以來,Nvidia股價連破50天及200天移動平均線,無論短線還是長線技術走勢均見利好。自四月低位計,Nvidia市值暴增約一萬億美元,超越蘋果,僅次於微軟,成為全球第二大市值上市公司。

這次反彈與2022年以來最大跌幅形成鮮明對比。上月低位時,Nvidia股價較一月歷史高位回落37%,當時市場憂慮科技巨頭晶片採購熱潮降溫,加上美中貿易緊張,影響Nvidia核心市場。

科技四巨頭加碼,AI資本開支創新高

事實上,科技巨頭並未縮減開支,反而更進一步。微軟、Alphabet(Google母公司)承諾明年進一步增加投資,Meta(Facebook母公司)亦因AI需求預期上調資本開支預算。連同亞馬遜,這四大企業2026年資本開支預計將達3300億美元,按分析師預測較今年增長6%。

雖然美國對華貿易政策仍存變數,但中東新商機令華爾街士氣大振。美銀(Bank of America)最新將Nvidia目標價由150美元上調至160美元,並重申買入評級。分析員Vivek Arya預計,沙特阿拉伯基建項目每年或為Nvidia和競爭對手AMD帶來多達50億美元收入,有助彌補因對華出口限制而失去的銷售額。

估值回升但未過熱,增長遠超大市

目前,87%彭博追蹤的分析員建議買入Nvidia,股價較平均目標價低約兩成,於「七巨頭」(Magnificent Seven)中僅次於Alphabet的潛在升幅。

Nvidia估值自2019年以來最低水平反彈,現時預期市盈率為28倍,仍低於過去十年平均的35倍,亦僅較標普500指數的21.6倍高出一點。公司預計2026財年收入增長54%,遠高於標普500預計的4.4%。Nvidia下次業績將於5月28日收市後公布。

Ingenium Analytics總裁Andre Bakhos表示:「通常這種增長型公司估值都會很高,但Nvidia現時估值與多年低位或大市相若,反映其投資吸引力。現時所有指標都利好Nvidia:技術走勢、估值、增長動力,尤其是中東新市場。這證明當基本面強勁時,要打破趨勢並不容易。」

編輯評論:Nvidia的「派對」會否無限延續?

Nvidia這次反彈,反映AI產業鏈已成全球資本市場新主軸。值得留意的是,科技巨頭的資本開支已不單止是「燒錢」搶佔市場,而是AI基建成為企業核心競爭力的根本。Nvidia作為AI硬件的「水喉」,其地位暫時難以撼動。

不過,這場「派對」真的可以無限延續嗎?首先,AI熱潮帶動的資本開支能否持續高增長?一旦AI應用商業化放緩,或新一輪技術突破令硬件需求大幅變動,Nvidia現時的高增長預期隨時面臨修正。其次,美中科技戰雖暫時和緩,但地緣政治變數始終難以預測。萬一制裁再度收緊,Nvidia在中國市場的潛在損失不容忽視。

再者,估值雖然未算過熱,但28倍預期市盈率已反映市場對其未來增長的高度信心。若未來AI基建投資出現任何風吹草動,資本市場的反應必然劇烈。

最後,值得香港投資者關注的是,Nvidia的故事其實是全球科技產業結構大變革的縮影。AI不單止是美國巨企的遊戲,中東、東南亞等新興市場的參與,令全球科技產業鏈分布更趨多元。香港作為國際金融中心,如何把握AI產業鏈資本流、技術流和政策博弈帶來的新機遇,值得深思。

Nvidia的派對現在仍然熱鬧,但「派對」永遠不會無限期進行。投資者要問的,是下一波音樂停下時,誰會坐得穩?

An ultra-realistic photograph of an Asian woman in the reference image, faithfully replicating my face and maintaining it 100%. A woman with a perfectly sculpted hourglass figure stands on the sand at sunset. She wears a white string bikini, measuring,+++ accentuating her curves with a well-defined waist, hips, and toned figure. Her skin is fair, smooth, and radiant.

She stands next to a large, ornate gold-framed mirror, perched upright on the sand, fully revealing her reflection. The reflection clearly emphasizes her silhouette, curves, and body proportions.

The lighting is cinematic and stunning, creating soft highlights on her skin and sharp shadow contrasts that enhance the shape of her waist, hips, and legs.

The background features a dusk sky with sunset tones of deep blue, purple, and orange, gentle clouds, and the silhouettes of palm trees.

A natural beach atmosphere, realistic textures, sharp focus on the woman's body and reflections, high detail, Ultra HD, artistic aesthetic, warm lighting, and low angle. [Subject]: Young Asian female with "Imada Mio-inspired" doll-like aesthetic (精緻洋娃娃臉). She has large round expressive eyes, a small V-line face, and rosy cheeks. Her expression is innocent, energetic, and slightly flirty. [Hair]: Messy morning hair (剛睡醒的凌亂感), long dark brown hair, slightly tousled, natural volume. [Outfit]: Wearing an oversized translucent white button-down shirt (男友風白襯衫), unbuttoned at the top to reveal collarbones, creating a "bottomless" look (下衣失蹤風格). [Style]: Japanese Gravure Photobook style (寫真集風格), Pure & Sexy vibe, bright high-key lighting, soft skin texture, Fujifilm PRO 400H color tone. Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a captivating studio portrait of a woman with long, wavy brown hair, seated gracefully on a stool in a thoughtful pose. She is wearing a long, flowing red gown with a one-shoulder design and a thigh-high slit, exuding elegance and sophistication. Her head is slightly tilted, with one hand gently resting on her chin. One leg is slightly extended, revealing a delicate ankle bracelet. Her makeup is polished and natural, featuring defined eyebrows, subtle eyeshadow, mascara, and a berry-toned lipstick. She wears delicate earrings and a gold bracelet that add a touch of sparkle to her overall look. The lighting is soft and diffused, creating a warm and flattering effect that emphasizes her beauty and the flowing lines of the gown. The background is a plain, brown, providing a warm and neutral backdrop. *** The composition is a full shot, capturing her from head to toe, framed vertically to accentuate her height and the flowing lines of the gown. The model is positioned in the center of the frame, creating a balanced and harmonious composition. The overall style is classic, elegant, and timeless, reminiscent of portrait photography, evoking a sense of grace, sophistication, and enduring beauty.
