SPDR S&P 500 ETF Trust (SPY)
7.32% of book · Avg. cost $655.24 · Return +14.01%
SPY tracks an index rather than running a business, so a competitor comparison in the sense used elsewhere on this site doesn't apply — the honest equivalent is VOO and QQQ, both held directly, compared in each other's fundamentals tables.
Investment Thesis
The Thesis
SPY tracks the S&P 500, giving broad, low-cost exposure to the U.S. large-cap market as a counterweight to the book's concentrated single-name bets. There's no stock-picking edge here — the case is entirely that owning the market is a legitimate default when I can't prove I'm beating it.
The Catalyst
There isn't one — SPY isn't held for a near-term event, it's held because my Investment Policy Statement requires an always-on index-hedge ballast, and SPY doubles as the book's official benchmark for time-weighted return comparisons.
The Risk
The real risk isn't to SPY itself, it's to my own discipline: if the rest of the book can't beat SPY over time, policy says to own more of it and say so plainly, rather than quietly keep taking single-name risk for no demonstrated edge.
The Connection
Deliberately theme-agnostic — SPY is broad-market ballast held specifically to counterweight the AI/semiconductor concentration in the rest of the book, not an expression of that theme.
SPY tracks the S&P 500 and is also my benchmark under the Investment Policy Statement: every letter measures the book's time-weighted return against it. P/E, EPS, and PEG aren't meaningful metrics for a broad index fund the way they are for a single company, so I'm not forcing them in here. SPY's expense ratio is 0.09%. Its top holdings by weight (Nvidia, Apple, Microsoft, Amazon, Alphabet) are also individually-held positions elsewhere in this book, which is part of why QQQ is honestly the weaker hedge of the two — see its position page.

Why I hold it
Policy requires an always-held index-hedge ballast, and it forces intellectual honesty: if the rest of the book can't beat SPY over time, the policy says to own more of it and say so plainly, rather than quietly keep taking single-name risk for no edge.
Macro Stress-Test: How SPY Fits In
The book-level stress test runs four scenarios against the whole portfolio. Here is exactly where SPY sits in each one — named directly, or not addressed at all. Nothing below is invented for this page; it’s the same book-level analysis, filtered to this position.
Current positioning, no shock assumed
SPY is 7.06% of the book, in the Index Funds sector. See the full base-case positioning on Holdings.
Where this position sits in the book’s least-defended scenario
SPY is part of the 19.18% index-hedge sleeve the book-level analysis names as its only broad mitigant here — and that analysis is explicit that broad-market ballast is not an inflation-specific hedge. This position provides diversification, not inflation protection.
Index-hedge ballast, not inflation-specific
Where this position sits in the book’s best-defended scenario
SPY is a liquid, publicly traded security like every other position in the book — no private equity, no illiquid credit, no lockups. A genuinely broad market drawdown would still hurt (the book’s beta is 1.79), but this position doesn’t face the structural exit friction an illiquid holding would.
Liquid, publicly traded
Where this position sits in the book’s largest concentrated risk
Not part of the semiconductor sleeve this scenario is built around. SPY sits in Index Funds, so a Taiwan-centered supply disruption would hit this position only indirectly, if at all, through broader market effects.
