Asian stocks appeared set to extend Tuesday's sharp losses following a brutal tech-led selloff on Wall Street that intensified worries the artificial intelligence-driven rally had stretched too thin. The overnight carnage in US technology shares created a negative lead for regional markets, with investors likely to dump riskier assets at the first opportunity.

The selloff centered on technology companies that had powered much of the recent market gains, particularly those tied to AI enthusiasm. As these high-flying names took a beating, it raised fresh questions about whether equity valuations had become disconnected from fundamentals. The tech-heavy Nasdaq's sharp decline overnight became the immediate catalyst for further downside pressure across Asia.

Market participants now face a critical assessment of whether the AI-fueled rally represented genuine value creation or speculative excess. The rapid unwinding suggests investors are reconsidering positions in companies that benefited from artificial intelligence optimism without corresponding earnings growth.

Risk sentiment has clearly shifted, with the immediate focus on preserving capital rather than chasing momentum. The developments signal a potential inflection point where speculative enthusiasm gives way to more disciplined valuation scrutiny.
