Nvidia Weighs on Tech Stocks as Nasdaq Composite Falls 1.5%

Market pullback: Technology stocks perform poorly

On August 19, 2025, the U.S. stock market experienced a pullback, with the Nasdaq Composite Index falling 1.5%, marking the largest single-day drop in nearly two months. Tech stocks were generally under pressure, with Nvidia’s stock price declining 3.4%, becoming a major factor in dragging down the index’s performance.

NVIDIA: AI leading stocks face challenges

As a global leader in AI chip manufacturing, NVIDIA’s stock price has risen by over 150% in the past year, with its market value once exceeding $1 trillion. However, recently the company’s stock price has experienced a fall, with the main reasons including:

• Overvaluation: Despite the company’s strong performance, the rapid increase in stock prices has raised investors’ concerns about a valuation bubble.
• Unclear AI Profit Models: Some analysts point out that the profit models for AI technology are still unclear, which may lead to investment returns falling short of expectations.
• Macroeconomic uncertainty: The expectation of a possible interest rate hike by the Federal Reserve has increased market uncertainty, affecting the performance of technology stocks.

The AI boom is cooling down, and market sentiment is weakening.

Besides Nvidia, other AI-related companies such as Palantir and AMD have also seen significant falls. Palantir’s stock price fell by 9%, making it one of the biggest falling tech stocks of the day. The market’s excessive optimism about AI technology may lead to a valuation bubble, and investors should remain cautious.

Investors should remain cautious.

In the face of the current market environment, investors should pay attention to the following points:

• Focus on the company’s fundamentals: choose those companies that have real application scenarios in AI technology and clear profit models.
• Diversify investment risks: Avoid concentrating funds in a single industry or company to reduce investment risks.
• Pay attention to macroeconomic trends: closely monitor the changes in the Federal Reserve’s monetary policy and the impact of the global economic situation on the market.

summary

Although AI technology is considered an important direction for future development, the current market’s excessive optimism towards it may lead to a valuation bubble. Investors should remain cautious, pay attention to the company’s fundamentals and macroeconomic trends, and allocate their investment portfolio reasonably to cope with potential market fluctuations.
