Why now
Waste Management · market cap $64.5b. 13% off the 52-week high of $238.62. 24 sell-side analysts rate this a Buy with a mean 1-yr target of $245.38 (implying +18% upside).
Moat
Net margin 13% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 18% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 120% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Mature compounder — the risk is paying up for quality at a moment when growth is decelerating. Watch for sequential revenue + margin trends; the inflection from "compounder" to "ex-compounder" is hard to spot until the multiple already started compressing.
ZWSZurn Elkay Water Solutions Corporation
Why now
Pollution & Treatment Controls · market cap $8.8b. 4% off the 52-week high of $55.00. Revenue growing +10%, comfortably above the S&P median. 10 sell-side analysts rate this a Buy with a mean 1-yr target of $58.10 (implying +10% 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 13% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 145% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Trailing P/E 33x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
