A Letter About Discipline.

Most equity research is opinion. Some of it is data. Very little of it is discipline.

Spinel Capital Research is built around a narrow and consistent discipline: identifying public companies where a clear, datable catalyst is poised to force a re-rating that the market has not yet priced over a twelve-to-twenty-four month horizon, taking positions where the downside is bounded and the upside is asymmetric, and writing the entire thesis down, including the exit, before the position is taken.

This first letter exists to make explicit what that discipline is, how I will apply it in every published deep-dive thesis, and what you can hold it accountable to. The framework is presented in three pillars, followed by the operational test that each idea must pass before it becomes a published thesis. The first live thesis follows within the next four weeks.

What Spinel Is, and What It Is Not

Spinel Capital Research is an independent equity research letter.

The universe is global and unrestricted by market capitalization. Spinel will follow opportunity wherever it sits: Europe, North America, Asia, large cap, mid cap, occasionally small cap when liquidity permits. What it will not do is dilute its conviction by writing about names that do not clear a high bar of asymmetric risk-reward.

The letter is published in two formats. Once a month, a deep-dive note dedicated to a single thesis examined at the level of detail required to actually take a position: origin of the mispricing, catalyst, valuation framework, bear case, exit framework with explicit upside target and invalidation level. Once a week, Spinel Weekly publishes shorter work in three defined categories: Research Notes, devoted to a single company that holds analytical interest but does not clear the three-pillar bar required for a Deep Dive; Industry Notes, focused on a sector observation, a thematic lens, or a cycle worth understanding; and Portfolio Notes, dedicated to post-mortems on closed positions, six-month reviews of published theses, and the written acknowledgment of what worked and what did not.

Once a month, Spinel Weekly publishes The Rejects, a short module listing three to five names that were considered and screened out, with the reason for rejection stated in two or three lines per name. You see the work that did not make the cut, which is where most of the discipline actually lives.

The deep dive is the work. The weekly is the thinking that surrounds it.

What Spinel will not do is equally important. The deep-dive mandate covers long-only equity, single-name, catalyst-driven theses. It will not cover cryptocurrency, private equity, venture capital, or any asset class outside listed equities, and it will not recommend short positions, options strategies, or leveraged products. The Weekly format is wider in scope, but the underlying philosophy remains the same: rigorous, written analysis, no hot takes, no signal flow, no momentum chasing. Macro reflections and sector observations are welcome where they sharpen the work; predictions about indices and market timing calls are not.

The track record will be public, but it will not be my personal trading account. Every deep-dive thesis published in Spinel will be tracked in a single, transparent Model Portfolio, with entry prices set at the close on the day of publication. The Model Portfolio exists to provide a fully auditable record of the research over time: every winner, every loser, with no cherry-picking and no rewriting of history.

A word on why the Model Portfolio is not my personal book. I am subject to professional constraints that affect personal trading. Certain names covered in these pages cannot be held personally. Others can, in sizes and timings that may differ materially from the model. Conflating the two would compromise both: the research, by narrowing the universe to what I can trade, and the personal book, by exposing it unnecessarily. The Model Portfolio is the discipline of the work made visible. Where my personal positions stand at any given time is not the subject of this letter.

Three Pillars

Every investment discipline has to answer one question: where does the edge come from? Without a clear answer, what looks like skill is usually just exposure to a market regime that happened to work. The work of Spinel rests on three answers, each one a pillar without which the discipline cannot stand.

Contrarian: Mispricing from the Collapse of Attention

Markets are not always wrong. They are wrong in specific, recurring ways. The most reliable of these is the collapse of attention. When a company falls out of the narrative (when sell-side coverage thins, when retail interest moves elsewhere, when the sector becomes structurally uninteresting to allocators), the price detaches from the underlying business in a way that the price of well-followed companies rarely does. That detachment is the mispricing Spinel is built to find.

The contrarian pillar is not about being negative on what the market loves, or positive on what the market hates. It names a specific source of mispricing (the absence of competition for information), not a posture of disagreement with consensus. A position that requires the entire market to be wrong about something obvious is a bad position. A position that only requires the market to start paying attention again is a good one.

Catalyst-driven: A Datable Reason to Be Right

A cheap stock that stays cheap is not a thesis. It is a value trap. The bridge between mispricing and return is a catalyst: a specific event, change of cycle, or shift in narrative that forces the market to update its assumptions. Without one, the position has no horizon and no falsifiability. With one, it has both.

A catalyst is not merely an event. It is an event capable of changing the market's expectations. Most quarterly results, most product launches, and most management appointments are events that pass without forcing a reassessment. The distinction matters: the test of a catalyst is not whether it occurs, but whether its occurrence forces the market to re-price.

Catalysts come in several forms. Some are corporate: an acquisition, a partnership, a divestiture, a management change, the launch of a product that meaningfully shifts the revenue mix. Some are cyclical: the trough of a commodity cycle, the inflection of a memory market, the moment a sector emerges from over-supply. Some are narrative: a thematic re-rating that pulls overlooked names into the conversation.

Every Spinel deep-dive thesis will identify the catalyst explicitly, with a stated horizon. If the catalyst materializes and the position does not move, the thesis was wrong about the link between the two, and that will be written. If the catalyst fails to materialize within the horizon, the position will be closed and the work re-examined in writing. The catalyst is the contract.

Asymmetry: The Only Acceptable Shape of a Position

Stock picking is not a game of being right more often than wrong. It is a game of being right by a lot when right, and wrong by a little when wrong. The first part is well understood. The second is where most investors lose.

Every position taken by Spinel must satisfy a minimum asymmetry test before publication. The downside scenario (defined as a credible, examined, written-down bear case) must be limited, ideally bounded by tangible value, replacement cost, or a floor in cash flows that the market has already priced. The upside scenario (defined as the thesis playing out on its stated horizon) must offer at least three times the downside in expected return. Positions that do not clear this bar do not get written about, however interesting the story.

The asymmetry test is what makes contrarian, catalyst-driven investing survivable. Being early is the same as being wrong, except when the downside is already priced in. Then being early is just being patient. The whole discipline collapses without this final filter.

Every thesis begins with a reason to buy and a reason to sell. I write the latter before the position is taken.

The Three Together

Each pillar on its own is insufficient. Contrarian without a catalyst produces a value trap. A catalyst without contrarian positioning produces a crowded trade where the upside is already in the price. Asymmetry has nothing to filter when the first two are absent: the opportunities never arise. The three together produce the only kind of position worth writing about: a mispriced company, with a datable catalyst, bought at a price where being wrong costs little and being right pays a lot.

Every deep-dive note published in these pages will be evaluated against these three pillars. Where a thesis fails the test, the position is not taken. Where it passes, it gets the full treatment. The Weekly format is not bound by these pillars in the same way; its purpose is to develop the broader thinking that informs the work, including analyses of companies that will never become Spinel positions.

What Qualifies as a Spinel Idea

The three pillars describe the philosophy. They do not, on their own, tell you what an idea must look like to clear the bar. The operational test is simpler, and it is written here so that you can hold every published Deep Dive accountable to it.

A Spinel idea must satisfy, in writing, before any position is taken:

A clear market misunderstanding. What does the market believe today, and why is that belief incorrect, incomplete, or stale?

A catalyst that can reasonably occur within twenty-four months. What event, on what horizon, will force the market to update its expectations?

A downside that can be articulated before entry. What is the bear case, what already protects capital if the thesis fails, and what does the market already price in?

An explicit exit framework. At what price does the thesis play out, at what price does it require re-examination, and at what price is it abandoned?

A risk/reward profile of at least three to one in the investor's favor. How much is being risked, against how much is potentially gained, on the stated horizon?

If I cannot answer those five questions clearly, in writing, I do not write about the idea. The objective is consistency of thinking, not mechanical screening. The consistency is real, and you are invited to check it against every published thesis.

What Comes Next

The first live Spinel thesis will publish within the next four weeks. It will follow the structure that every future deep-dive note will follow: origin of the mispricing, catalyst identified, valuation framework, bear case, exit framework with explicit upside target and invalidation level. The position will be timestamped at publication, entered into the Model Portfolio at the closing price that day, and held accountable to its written framework from that moment forward.

Between deep dives, Spinel Weekly will publish a shorter piece each week, in one of the formats described above.

A few commitments worth stating plainly. I will publish an explicit exit framework with every deep-dive thesis, including an invalidation level. I will review performance publicly each quarter, with no cherry-picking and no rewriting of history. Closed positions, winners and losers, will be discussed with the same prominence as new entries. When a thesis breaks, I will say so in writing, placing the original reasoning and the corrected reasoning side by side.

Spinel is built slowly, on purpose. The discipline of the letter is the discipline of the work it describes.
