The companies
SMCISuper Micro Computer, Inc.
Why now
Computer Hardware · market cap $20.4b. Down 46% from 52-week high of $58.78 — 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 +20% 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 46% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.97 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
STXSeagate Technology Holdings plc
Why now
Computer Hardware · market cap $181.5b. Down 30% from 52-week high of $1145.00 — deep drawdown territory. Revenue growing +34% — in hypergrowth territory. PEG 0.46 — paying under fair value for the growth rate. 23 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $1,116 (implying +39% upside).
Moat
Net margin 26% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. FCF converts 98% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined. $181.5b 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
Trailing P/E 57.6x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Down 30% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.10 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.

Where SMCI and STX diverge

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.
