2026最大市場風險:AI估值泡沫崩潰?




德意志銀行調查:2026年最大市場風險為人工智能估值崩潰

根據德意志銀行最新的全球市場調查結果,與人工智能(AI)相關的估值風險已成為2026年市場穩定性的最大威脅。該調查於12月中旬進行,收集了全球440位投資者及市場參與者的回應。

調查顯示,有57%的受訪者認為,因市場對人工智能熱情減退而引發的科技股估值暴跌,是明年市場面臨的最大風險。德意志銀行策略師Jim Reid在報告中指出:「我們從未見過某個風險在未來一年內能如此明顯領先其他風險,AI及科技泡沫風險遠遠超越其他威脅。」

在風險排序中,AI風險與其他威脅之間存在明顯差距。第二大擔憂由27%的受訪者提出,主要是擔心美聯儲新主席可能推動激進降息政策,導致市場動盪。接著是22%受訪者憂慮私人資本市場危機,以及21%擔心債券收益率超預期上升。另有15%受訪者關注由於通脹持續,央行可能被迫意外加息。

儘管AI在風險評估中佔主導地位,調查同時顯示,美國科技股的泡沫擔憂在過去一年內並未明顯加劇。Reid表示:「雖然美國科技股泡沫風險感知仍然偏高,但在2025年並未大幅上升,且低於9月和2021年的水平。」

受訪者在泡沫風險評分中給予美國科技股約7分(滿分10分),高於其他主要資產類別,而其他如信貸市場的估值雖然偏高,但並不被認為極端。

調查還反映出投資者對美國大型科技股保持謹慎態度。約71%的受訪者表示,寧願持有美股指數中除「壯麗七巨頭」外的其他股票作為退休金投資,這一偏好自2024年7月以來基本穩定。期間,「壯麗七巨頭」上漲約25%,而指數其他部分僅漲約16%。

對於2026年,受訪者對該七大科技股的回報預期較為謹慎,預計平均回報約7%,較2025年約25%的漲幅明顯放緩。整體標普500指數的平均回報預期接近7%,為過去四年調查中最樂觀。

此外,AI在工作中的應用持續擴大。只有14%的受訪者表示尚未在工作中使用AI工具,較2024年夏季接近一半的比例大幅下降,且歐洲的使用率略高於美國。

調查還顯示,對宏觀經濟的擔憂有所減輕。預期美國未來12個月內出現經濟衰退的比例持續下降,僅8%的受訪者認為經濟衰退概率超過50%。

編輯評論與深度分析

德意志銀行這項調查反映出市場對AI相關科技股估值泡沫的警覺性達到新高,這與近年來AI技術熱潮帶動的資金狂潮密切相關。市場過度追捧AI概念,推高估值至難以持續的水平,一旦市場情緒轉冷,估值崩盤的風險就會爆發,帶來劇烈的市場震盪。

不過,值得注意的是,該調查同時指出科技泡沫風險感知並未明顯加劇,這或許意味著投資者開始更理性地評估AI板塊,未再盲目追高。這種「冷靜期」可能是市場自我調整的過程,為未來更穩健的增長奠定基礎。

此外,投資者對「壯麗七巨頭」的偏好下降,顯示大型科技股不再被視為唯一的避風港,投資者更願意分散風險,尋找其他潛力股。這種態度有助於緩解單一板塊過熱帶來的系統性風險。

從宏觀經濟角度看,通脹持續與央行政策的不確定性依然是潛在變數,但相比AI估值風險,這些因素的擔憂程度稍顯次要。市場似乎更擔心科技估值的調整,而非宏觀經濟的劇烈波動。

對香港投資者而言,這份調查提醒我們在投資AI及科技股時要保持謹慎,避免追逐短期熱潮而忽略估值風險。同時,也應關注全球央行政策變化及資本市場流動性,因為這些因素將影響整體市場的風險偏好和資金配置。

總結來說,2026年的市場風險焦點從傳統宏觀經濟轉向科技估值泡沫,這反映了科技進步帶來的巨大機遇與潛在風險並存。投資者應該在享受AI帶來的成長紅利時,謹慎防範可能的估值調整,避免因過度樂觀而遭受損失。

Her complexion is flawless and softly bronzed with luminous highlights, brows are sculpted and powerful, cheeks carry a subtle coral-rose flush, and lips are finished in a refined nude-rose satin tone to balance the intense, artistic eye look."

} Base Setup

keep 100 percent facial information adherence of the attached image and turn her into a fashion model walking through a dim stone tunnel toward a bright exit, captured as a live action photograph or movie still, not an illustration or CGI render. Her styling leans seductive and attractive through fashion, attitude, and mood rather than explicit content.

Shot and Camera

Full body silhouette shot from behind at slightly low camera height, matching the original perspective and narrow tunnel framing. Keep her stride, tunnel curvature, and vanishing light exactly as seen.

Identity and Pose

Preserve her height impression, slim silhouette, hair length, and body proportions. She walks forward with one hip subtly angled, natural arm swing, confident stride, and a slow, sensual rhythm. Her head tilts slightly as if aware of being watched. Include 8k Photorealistic and hyper realistic.

Lighting and Environment

Strong backlight from the tunnel exit creates a glowing rim around her body, with soft, scattered reflections on the wet stone floor. The tunnel remains dark with textured stone irregularities and real moisture streaks. Add subtle haze for realism and keep the environment grounded with accurate shadows and surface wear.

Masking and Constraints

Change only the outfit and styling, keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same. Absolutely no added text, no cartoon look, no CGI sheen, no plastic skin, no floating feet, and no overly clean backgrounds. Maintain consistent perspective, grounded contact shadows, film like grain, and full live action realism. An intense, close-up portrait set in a smoky, underground jazz club or speakeasy. The subject is the 'Boss' of an information network, hiding in plain sight. The scene is dark, defined by heavy shadows and cigarette smoke swirling in the air. A single spotlight hits the subject from the side, creating a classic 'Rembrandt triangle' on the cheek of [exactly face uploaded image 100%]. He wears a sharp, pinstripe suit with a silk tie, loosened at the collar. He holds a glass of amber whiskey, the condensation rendered in 8K detail. The camera uses a macro 100mm lens, focusing entirely on the eyes and the texture of the skin, blurring out the background patrons into abstract shapes. The mood is conspiratorial, sophisticated, and deeply atmospheric.
