#AsteraLabs领涨芯片股 When "Connectors" Are Scarcer Than "Computing Power": The Logic Behind Astera Labs Leading Chip Stocks

On June 29, U.S. chip stocks staged a "deep V" reversal — the Philadelphia Semiconductor Index initially fell over 3% in early trading, but closed up 3.83%. The leader was not Nvidia, but a company founded only nine years ago: Astera Labs (ALAB), which surged 16.39% in a single day.
Who is Astera Labs? It does not make CPUs or GPUs, but focuses on interconnection technology for AI infrastructure — solving the data transmission bottleneck between chips within data centers, and is known in the industry as the "data highway" of the AI era. As the computing power arms race intensifies, data transmission efficiency has become the bottleneck, and the value of "connectors" is being repriced by the market.
The surge was driven by multiple catalysts: the company was just added to the Nasdaq 100 Index on June 22, releasing passive fund buying demand; the fundamentals were also solid, with quarterly revenue up 93% year-over-year and gross margin as high as 76.3%. More importantly, UBS released a research report that day, pointing out that CXL interconnection technology is entering an "inflection point," with the market size expected to approach $70 to $10B by 2030, and significantly raised its target price for Astera Labs. According to FactSet data, 21 analysts have raised the median target price from $260 to $270.
However, the other side of high growth is high valuation. The stock has risen over 150% year-to-date, with a forward P/E ratio exceeding 100 times. Yang Delong, chief economist of Qianhai Open Source Fund, stated bluntly: "The AI tech bubble is still in a frenzy." As market sentiment shifts from computing power to interconnection, Astera Labs stands at the forefront — but the sword of high valuation hanging overhead cannot be ignored.
