Index inclusion draws fresh attention to Astera Labs

Astera Labs (ALAB) has been added to the NASDAQ-100 Index, a move that can reshape how the stock trades as index funds and ETFs tracking the benchmark adjust their positions.

This index inclusion comes after strong share price gains over the past year, partly linked to AI-related demand. It also follows comments from Grow Funds about Astera Labs' decelerating growth rates and previously elevated P/E multiple.

Astera Labs has seen very strong momentum over the past year, with a 1 year total shareholder return of 354.99% and a 90 day share price return of 229.94%. However, the share price fell 9.70% in the last day to US$397.02 and remains volatile around its recent index inclusion and AI related enthusiasm.

With Astera Labs now in the NASDAQ-100, a very large 1 year return, and fresh questions about slowing growth rates and earlier P/E levels, investors are left wondering whether this is a genuine opportunity or if the stock is already pricing in future growth.

Most Popular Narrative: 62.1% Overvalued

Astera Labs last closed at $397.02, while the most followed narrative pegs fair value at $244.97, creating a wide gap between market price and modeled worth.

Strong early engagement with hyperscalers and AI platform providers on open, interoperable standards like UALink (which are still in the early adoption phase with projected ramp in 2027 and beyond) enables Astera Labs to capture the industry's shift toward open, multi-vendor AI Infrastructure 2.0. This ensures exposure to significant long-term market expansion and incrementally larger addressable markets, with a positive impact on revenue growth rates and future margin potential as adoption accelerates.

Want to understand why this narrative still supports a rich valuation gap? The model leans on rapid revenue expansion, high earnings growth and premium profit margins. Curious which assumptions matter most and how sensitive that fair value is to small changes in them? The full narrative lays those moving parts out in detail.

Result: Fair Value of $244.97 (OVERVALUED)

However, Astera Labs still faces two clear swing factors: any sustained slowdown in hyperscaler AI capex, or rapid shifts toward in house interconnect solutions from larger chipmakers.
