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
ALSNAllison Transmission Holdings, Inc.
Why now
Auto Parts · market cap $11.0b. 3% off the 52-week high of $137.62. Revenue growing +38% — in hypergrowth territory. PEG 0.66 — paying under fair value for the growth rate. 10 sell-side analysts rate this a Buy with a mean 1-yr target of $139.40 (implying +5% upside).
Moat
Net margin 12% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 27% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 139% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
D/E 2.12 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer.
GNTXGentex Corporation
Why now
Auto Parts · market cap $5.0b. 20% off the 52-week high of $29.38. Revenue growing +10%, comfortably above the S&P median. PEG 0.73 — paying under fair value for the growth rate. 9 sell-side analysts rate this a Buy with a mean 1-yr target of $27.78 (implying +18% upside).
Moat
Net margin 15% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 16% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 122% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Value re-rating depends on a catalyst. Without one — analyst day, divestiture, margin recovery, capital return — the stock can stay cheap on these multiples for years.

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.
