Side by side · every name on one set of axes
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
KTKT Corporation
Why now
Telecom Services · market cap $9.3b. Down 20% from 52-week high of $24.58 — deep drawdown territory. 4 sell-side analysts rate this a Buy with a mean 1-yr target of $21.94 (implying +12% upside).
Moat
FCF converts 133% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Net margin 1.5% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first. ROE 2% 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.
Why now
Telecom Services · market cap $190.7b. Down 31% from 52-week high of $258.66 — deep drawdown territory. PEG 0.84 — paying under fair value for the growth rate. 24 sell-side analysts rate this a Buy with a mean 1-yr target of $243.38 (implying +37% upside).
Moat
ROE 19% sits above Buffett's preferred 15% threshold — 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, a sign that working capital and capex are well-disciplined. $190.7b 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 31% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

- ValueKT 27.0 · TMUS 67.3TMUS +40.3
- GrowthKT 42.9 · TMUS 73.9TMUS +31.0
- QualityKT 45.9 · TMUS 73.6TMUS +27.7
Pillars run 0–100 against sector peers, so a 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.
