February ends with a clear cooling of sentiment in financial markets, driven by growing concerns about the profitability of investments in artificial intelligence. Despite Nvidia's record revenues, the market reacted with declines, fearing that growth momentum may slow. The sell-off also hit Nasdaq, and worries about AI infrastructure costs impacted stocks of smaller players like CoreWeave, despite rising capital expenditures in the industry.

A standard of high energy-saving performance

It contains five heat insulation system designs, effectively balancing window and wall warmth, resulting in the U-value of doors and windows reaching low levels, suitable for low-energy buildings.

Sound insulation performance

Invisible hardware and deep pressure stripes, reaching 45 decibels with triple-paned glass.

Water tightness and hidden drainage design

A hidden drainage drainage system with the high and low-pressure principle is used to prevent rainwater backflow or leakage during strong winds and rain. In addition, the hollow section of window adopts a split structure, a waterproof soft adhesive and hard adhesive, resulting in more durable and stable physical performance.

Profile strength and wind resistance

Multi-cavity structure, with scientific reinforcement positions and reasonable heat insulation material. The strip is integrated with the profile to achieve high mechanical performance of the product, which is very helpful for the seismic resistance and window wind pressure resistance.

Aesthetic style

With invisible hinges and flush window sash, the appearance is simpler and cleaner, and the overall effect is more luxurious.

The final days of February on global stock markets were marked by high volatility, triggered by a recalibration of expectations towards the artificial intelligence sector. Although giants like Nvidia and Dell Technologies presented solid financial results, they failed to calm investors. Dell recorded a 39% sales jump in the fourth fiscal quarter of 2026, driven by demand for AI-serving servers, but markets focused on risks related to margins and the huge costs of maintaining market position. Investors began taking profits, leading to declines in futures contracts on major indices, including the technology-heavy Nasdaq. The market situation was complicated by reports from companies building cloud infrastructure. CoreWeave saw a drop in stock value after doubling its investment outlays raised concerns about future operational profitability. This phenomenon shows a new market mechanism: investors no longer reward mere announcements of artificial intelligence development, but rigorously assess the cost-to-real-profit ratio. Jensen Huang, head of Nvidia, faced an audience demanding proof of another breakthrough, indicating growing pressure on industry leaders. Even the introduction of new Vera Rubin architecture chips did not stop the market correction. The current euphoria around AI is often compared to the dot-com bubble at the turn of the century, when excessive optimism about internet companies led to a sharp market crash in 2000. Simultaneously, inflows into global equity funds fell to the lowest level in five weeks, and Asian markets, including South Korea and India, also felt the global cooling. Hyundai Motor Group announced a $6.3 billion investment in AI data centers and a robot factory, but sentiment in Seoul remained subdued after foreign funds withdrew nearly $5 billion from the local stock market.
