Spread of AI Investment Skepticism and Tech Stock Correction: From Vague Expectations to the Era of Profitability Verification

Core Reason for Tech Correction: Demand for Fundamental Verification

The recent upward trend in major US stock indices has faltered, leading to a broader correction in tech stocks. The driver of this decline is not merely macroeconomic factors, but the market's strict verification of the revenue-generating capabilities of Artificial Intelligence (AI) related companies. With the generative AI boom that has persisted since 2024, the Price-to-Earnings (P/E) ratios of major Big Tech and semiconductor equipment companies have exceeded historical averages, exacerbating valuation burdens.

The Gap Between Massive CAPEX and Profitability

The primary factor fueling market skepticism is the speed of visible earnings (EPS) growth compared to the scale of capital expenditures (CAPEX) by major tech firms.

• Burden of Capital Expenditure: Global Big Tech companies are pouring astronomical sums into building AI infrastructure and expanding data centers.
• Questions on Return on Investment (ROI): Investors have begun demanding concrete numbers on when these massive costs will translate into increased cloud revenues and tangible improvements in corporate operating margins.

Due to this shift in sentiment, the market is no longer satisfied with the mere 'AI theme' label. Funds are concentrating exclusively on companies that present solid earnings guidance that meets or beats expectations, intensifying a rigorous filtering process within the stock market.

Spillover Effects on the Hardware Supply Chain and Outlook

This demand for profitability verification is affecting the entire supply chain, from chip designers like Nvidia to domestic semiconductor materials, parts, and equipment suppliers. There are underlying concerns that if Big Tech's capital investments are restructured for efficiency or temporarily slow down, the guidance for companies within the related hardware value chain could also face downward revisions.

Paradigm Shift from Momentum to Real Performance

The current volatility in the tech sector does not negate the long-term growth potential of the AI industry itself. Rather, it is a natural price discovery process that must occur before the industry enters a mature phase. It signifies that the market's focus is shifting from vague growth momentum to concrete corporate earnings and cash-flow generation capabilities.

Investors are required to adopt a conservative approach, closely evaluating whether a company's business model is actually reducing costs or creating new revenue streams through AI.
