Semiconductor shares have ridden the AI wave to eye-popping heights. Knowledge facilities now devour chips for coaching and working massive language fashions, pushing the sector’s valuations sky-high. But good buyers know not each high-flyer delivers lasting returns.
To search out shares to purchase in immediately’s market, legendary investor Peter Lynch, who grew the Constancy Magellan fund from $18 million to over $14 billion in belongings — a 29% compound annual return — throughout his 14-year tenure, would doubtless attain for a similar simple instruments that any retail investor might grasp.
Lynch targeted on comprehensible companies with strong earnings progress and cheap costs. One device he leaned on closely was the PEG ratio, his go-to display screen for recognizing progress shares earlier than the gang caught on. It basically requested how a lot are you paying for every unit of progress? For Lynch:

PEG of 1.0x — pretty valued
-
PEG beneath 1.0x — probably undervalued
-
PEG above 2.0x — what Lynch typically considered this because the “hazard zone”
Now let’s apply that lens to a few of immediately’s semiconductor leaders:
These are high-quality companies, however primarily based on Lynch’s framework, buyers are paying steep premiums for his or her progress. Surprisingly, two AI-driven chip shares sit on the reverse finish of the spectrum — Marvell Expertise (NASDAQ:MRVL) at 0.6x and Micron Expertise (NASDAQ:MU).
Marvell Expertise has quietly turn out to be a key provider to the AI infrastructure buildout. As a substitute of competing head-on with giants like Nvidia (NASDAQ:NVDA), Marvell focuses on customized silicon, networking chips, and knowledge heart connectivity — the plumbing behind AI. Its chips deal with the high-speed Ethernet connections and optical modules that allow AI servers discuss to at least one one other at blistering speeds. AI demand has expanded the enterprise quickly.
In keeping with Marvell’s newest earnings launch, knowledge heart income now accounts for over 70% of complete gross sales, and that section grew over 50% yr over yr. That’s not theoretical progress — it’s already occurring.
Right here’s what the numbers inform us:
Though a 30x earnings a number of would possibly sound excessive in isolation, however when earnings are rising at roughly 50%, the PEG compresses shortly. That’s precisely the type of mismatch Lynch appeared for.
Past PEG, Lynch additionally appreciated comprehensible companies with clear demand drivers. Marvell checks that field. Hyperscalers like Amazon (NASDAQ:AMZN) and Microsoft (NASDAQ:MSFT) are designing customized AI chips, and Marvell helps make that attainable. That creates long-term design wins, not simply one-off gross sales.
Granted, Marvell isn’t risk-free. Buyer focus is actual, and customized chip cycles could be uneven. However with AI infrastructure spending nonetheless increasing, the expansion runway stays intact.
If Marvell is the infrastructure enabler, Micron Expertise is the gas provider. Reminiscence — DRAM and NAND — is important for AI workloads, and demand is rising quick. AI has supercharged the necessity for its high-bandwidth reminiscence (HBM), the specialised DRAM that feeds knowledge to GPUs at file speeds.
That final level issues. HBM is vital for AI accelerators, and Micron has locked in provide commitments properly forward of manufacturing, with provide for 2026 already bought out beneath long-term contracts. In fiscal Q2 2026, Micron reported income of $23.86 billion — up 196% year-over-year — with DRAM income alone rising 207%.
Now have a look at valuation:
That’s not slightly below Lynch’s threshold — it’s a fraction of it.
Traditionally, reminiscence shares commerce cheaply due to boom-and-bust cycles. Lynch knew this and infrequently leaned into cyclical names when the numbers justified it. The distinction immediately is AI demand is smoothing out a few of that volatility. Knowledge heart clients are putting longer-term orders, which reduces the same old pricing swings. The corporate additionally generates robust free money move and boasts a clear steadiness sheet relative to friends.
That mentioned, cycles don’t disappear totally. If reminiscence pricing weakens, Micron’s earnings can fall simply as shortly as they rise. That’s the trade-off buyers want to simply accept. Nonetheless, when all is alleged and executed, a 0.2x PEG ratio suggests the market isn’t absolutely pricing within the present progress trajectory.
