#芯片股集体反弹
I believe the artificial intelligence (AI)-driven semiconductor rally is not yet over; however, moving forward, the process will likely depend more on the actual financial results—specifically earnings performance—achieved by these companies, rather than on mere market euphoria.

The growth figures reported by AMD—most notably a 97% surge in data center revenue—are highly impressive. These data points reinforce the thesis that spending on AI infrastructure is not merely a product of speculative hype, but is instead translating into tangible commercial growth.

That said, strong earnings do not automatically mean a stock is "undervalued." Investors must also carefully consider factors such as corporate forward guidance, profit margins, the competitive landscape, and the extent to which projected growth is already priced into the stock.

Comparing AMD, NVIDIA, and Micron

My ranking varies depending on what an investor is looking for:

1. AMD — The strongest opportunity for a turnaround

As it expands its AI accelerator and server CPU business segments, AMD offers an attractive growth potential. Its revenue forecast of approximately $17 billion for the fourth quarter is particularly promising. The key question here is whether the company can successfully increase its market share while maintaining its profit margins.

2. NVIDIA — The most formidable and well-established leader in the AI ​​space

NVIDIA occupies an exceptionally advantageous position, thanks to its GPU ecosystem, software platform, and deep-rooted relationships within the data center sector. The company’s greatest strengths lie in its operational execution and scale; however, its high valuation and lofty market expectations also bring certain risks. 3. Micron — An interesting option for accessing AI infrastructure

High-bandwidth memory (HBM) is an indispensable component for advanced AI accelerators. Micron offers an opportunity to invest in this part of the supply chain; however, fluctuations in memory prices and the cyclical nature of the industry can lead to significant volatility.

It is worth taking a closer look at AMD’s results: the company’s revenue in the "client" (personal computer) and gaming segments fell by 8% year-over-year, revealing that growth is not equally strong across all business lines.

Micron, meanwhile, is particularly noteworthy; it reported a record revenue of $54.23 billion for the fourth quarter of its 2026 fiscal year and raised its revenue forecast for the following quarter to $61.5 billion. A large portion of the company’s HBM production for 2027 is already under contract.

How long could the rally last?

At this point, I believe it is necessary to monitor three key indicators:

* AI spending: Are major tech companies continuing to increase their investments in data centers? * Earnings growth: Are semiconductor companies growing their profits fast enough to justify their valuations?

* Supply constraints: Are manufacturers able to supply enough GPUs, HBM memory, and advanced computing systems to meet demand?

My trading strategy

* Avoid chasing large price surges that occur after the market closes.

* Consider gradual entry points rather than investing everything at once.

* Monitor earnings forecasts and revenue growth for confirmation. * Keep some cash on hand for potential market corrections.

* Re-evaluate your positions if spending on artificial intelligence infrastructure begins to slow down.

Conclusion: In my view, AMD has the strongest potential for a rebound, NVIDIA holds the most robust competitive position, and Micron presents an interesting opportunity within the memory sector.

The AI ​​boom may well continue, but rather than blindly chasing momentum, I prefer to invest in strong companies that are trading at reasonable valuations.
