Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
ALABAstera Labs, Inc.
Semiconductors · $342.21 · beta 3.69
Why now
Semiconductors · market cap $59.4b. Down 31% from 52-week high of $499.48 — deep drawdown territory. Revenue growing +98% — in hypergrowth territory. 22 sell-side analysts rate this a Buy with a mean 1-yr target of $391.77 (implying +14% upside).
Moat
Net margin 31% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 21% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. $59.4b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
Risk
Trailing P/E 168.6x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Down 31% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 3.69 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
MUMicron Technology, Inc.
Semiconductors · $1,029.00 · beta 2.23
Why now
Semiconductors · market cap $1.2T. 18% off the 52-week high of $1255.00. Revenue growing +256% — in hypergrowth territory. PEG 0.16 — paying under fair value for the growth rate. 46 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $1,555 (implying +51% upside).
Moat
Net margin 64% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 61% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. $1.2T market cap places it among the largest companies in the sector — distribution, R&D, and customer-acquisition costs amortize across a base peers can't replicate.
Risk
Beta 2.23 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Semiconductor cyclicality — inventory corrections compress margins faster than analysts model. Monitor channel inventory and book-to-bill ratios as leading indicators.

Where ALAB and MU diverge
On the headline score the gap is 11.4 points in favor of MU. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

Pillars run 0–100. Value is judged against each company's own sector, so a Value score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
Common questions
Is MU or ALAB the better stock?
MU scores higher: MU 82.1, ALAB 70.7 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.
Where do MU and ALAB differ most?
The widest gap is value, where MU leads by 22 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are MU and ALAB scored?
Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
How current is this comparison?
The whole universe is re-scored every trading day after the US market close, so the scores and fundamentals here reflect the latest published edition.
