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
SKMSK Telecom Co., Ltd.
Telecom Services · $34.24 · beta 0.75
Why now
Telecom Services · market cap $13.1b. Down 27% from 52-week high of $47.18 — deep drawdown territory. PEG 0.42 — paying under fair value for the growth rate.
Moat
FCF converts 172% of net income — earnings translate cleanly into cash.
Risk
Net margin 4.4% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first. ROE 5% is below the long-run sustainable threshold of ~10% — capital efficiency would need to improve for the equity base to compound at the market rate.
TMUST-Mobile US, Inc.
Telecom Services · $148.58 · beta 0.32
Why now
Telecom Services · market cap $159.4b. Down 36% from 52-week high of $230.65 — deep drawdown territory. PEG 0.61 — paying under fair value for the growth rate. 25 sell-side analysts rate this a Buy with a mean 1-yr target of $241.24 (implying +62% upside).
Moat
ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 174% of net income — earnings translate cleanly into cash. $159.4b 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
D/E 2.14 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 36% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

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 TMUS or SKM the better stock?
TMUS scores higher: TMUS 71.9, SKM 29.6 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 TMUS and SKM differ most?
The widest gap is growth, where TMUS leads by 56 points on the 0–100 pillar scale. TMUS leads all three pillars, so the gap is broad rather than a single-measure difference.
How are TMUS and SKM 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.
