The companies
SMCISuper Micro Computer, Inc.
Why now
Computer Hardware · market cap $18.0b. Down 55% from 52-week high of $62.36 — deep drawdown territory. Revenue growing +56% — in hypergrowth territory. PEG 0.91 — paying under fair value for the growth rate. 16 sell-side analysts rate this a Hold with a mean 1-yr target of $37.81 (implying +36% upside).
Moat
ROE 16% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Free cash flow is negative (-$6.8b) — capital raises or debt issuance likely required; dilution / leverage risk. Down 55% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.94 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
WDCWestern Digital Corp
Why now
Technology · market cap $150.9b. Down 34% from 52-week high of $799.87 — deep drawdown territory. Revenue growing +10%, comfortably above the S&P median.
Moat
Net margin 55% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 91% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. $150.9b 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
Down 34% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.25 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. P/S 12.8x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard.
