The companies
ENPHEnphase Energy, Inc.
Why now
Solar · market cap $4.9b. Down 50% from 52-week high of $73.74 — deep drawdown territory. 26 sell-side analysts rate this a Buy with a mean 1-yr target of $48.93 (implying +33% upside).
Moat
ROE 12% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 107% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 50% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.61 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Trailing P/E 36x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
FSLRFirst Solar, Inc.
Why now
Solar · market cap $21.9b. Down 37% from 52-week high of $320.95 — deep drawdown territory. Revenue growing +27% — in hypergrowth territory. PEG 0.54 — paying under fair value for the growth rate. 28 sell-side analysts rate this a Buy with a mean 1-yr target of $256.36 (implying +26% upside).
Moat
Net margin 31% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 17% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 100% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 37% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.73 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
