Full disclosure: Dombey Capital is our own research service and our top pick here, for the reasons below. The section on where it falls short is there so you can judge whether it fits your process.
Why so much stock research now lives on Substack
Substack lets a single writer publish a newsletter, set a price and keep a public archive without building a website or a payment system. That has pulled in former fund managers, sector analysts and forensic researchers who would once have written for a bank or a fund. The result is a wide choice of narrow newsletters, each doing one job.
That is also the main difference from a broad research service such as the ones in our list of Seeking Alpha alternatives. A Substack rarely covers the whole market. It covers one sector, one style or one kind of event, and the quality depends on one writer or a small team.
This list is broader than our guide to the best newsletters for special situations, which compares spin-off letters, idea clubs and institutional services. Here the common thread is the platform: every newsletter below publishes on Substack, and every price comes from its own subscribe page.

How we compared these tools
We compared these newsletters from their Substack subscribe pages, about pages and free posts, read on October 9, 2026. We did not use paid subscriptions for this article. Each newsletter was scored against five criteria, weighted toward what matters to a reader who acts on dated events and specific companies.
| Criterion | Weight | What it measures |
|---|---|---|
| Actionable focus | 30% | Whether posts end in a view on specific companies or events, not only commentary |
| Accountability | 25% | Whether past ideas get dated follow-ups that a reader can check |
| Depth | 20% | Whether the writer explains the mechanics, numbers and risks |
| Price and free access | 15% | Annual price, monthly price and how much is free |
| Clarity of the paid offer | 10% | Whether the subscribe page says plainly what paying adds |
If you read Substacks for general market context rather than for ideas, weight depth and price higher. The macro and sector letters, such as Apricitas Economics and Net Interest, then move up. We make no claims about any newsletter's returns or accuracy.

Each thesis is published before its catalyst, priced on the day and kept in the research archive.

It includes the weekly Phoenix Report, weekly Options Research, the Biweekly Catalyst Briefing, the DombeyAI Portal with the Daily Phoenix Screener and the Earnings Conviction Model, valuation and execution analysis, and priority access. Standard Access is the lower-cost option at $80 a year, about $6.67 a month, or $8 a month on monthly billing, and includes the Biweekly Catalyst Briefing and the complete public-research archive. Public posts are free.
Pros

What paying monthly really costs
Every newsletter here charges less for a year upfront than for twelve monthly payments. The table shows the gap, using the prices on each subscribe page.
| Newsletter | 12 x monthly | Annual plan | Saving with annual |

| Yet Another Value Blog | $2,814.72 | $649.46 | $2,165.26 |
Where Dombey falls short
Dombey is built for depth on a narrow set of situations. Its limits are specific:
- Narrow coverage. It covers special situations and dated catalysts only. A company with no event ahead will not be in it, and there is no sector or macro commentary like Net Interest or Apricitas offer.
- No data terminal. There is no broad screener or financial database for the general market. You still need SEC EDGAR or a data tool to check filings yourself.
- Small team. The number of situations covered at any time is limited.
- Pen-name author. The research is published under a pen name, which some readers prefer not to rely on.
- Short history. The archive is young compared with Substacks that have published for a decade, so there is less record to examine.
Free vs paid
Every newsletter on this list publishes something free, and that free layer is worth using before you pay. Yet Another Value Blog has more than a decade of free posts. The Bear Cave's weekly activist short recap is free. Apricitas Economics publishes weekly free articles. Dombey's public posts and Public Archive are free.
What paying adds differs sharply:
- If the paid tier unlocks the ideas, as at Yet Another Value Blog, Inside Arbitrage or Compounding Quality, the free posts show the style but not the current calls.
- If the paid tier unlocks timeliness, as with The Transcript's unredacted issue or How They Make Money's founding earnings visuals, you are paying for speed.
- If the paid tier unlocks depth, as at Net Interest or MBI Deep Dives, the free posts are a fair sample of what you would get.
How to choose
Start with the job you want the newsletter to do, then check whether its free posts do that job well.
| Your situation | Pick | Add later when |
|---|---|---|
| You follow special situations with dated catalysts | Dombey CapitalTop pick | You want more event types: add Inside Arbitrage |
| You want quirky value ideas with a long archive | Yet Another Value Blog | You want a dated, priced record: add Dombey Capital |
| You own financial stocks | Net Interest | You want earnings context: add The Transcript |
| You follow semiconductors | Fabricated Knowledge | You want visual results: add How They Make Money |
| You want to know when a holding is a short target | The Bear Cave | You want long ideas too: add Dombey Capital |
| You want macro context on a budget | Apricitas Economics | You want energy views: add Doomberg |
Before paying for any of them, apply the same test you would apply to your own work. Our guide on how to write a dated investment thesis sets out what a checkable idea looks like: a price, a date, a catalyst and what would prove it wrong. A newsletter that gives you those four things is easier to judge than one that does not.
The bottom line
Dombey Capital is our top pick on Substack for readers who want written research on special situations with dated catalysts, with Founding Membership at $1,200 a year for the full research suite and Standard Access at $80 a year or $8 a month as the lower-cost option. For a sector, Net Interest and Fabricated Knowledge are the clearest choices, The Bear Cave covers the short side, and The Transcript does the earnings season reading for you. Apricitas Economics is the low-cost pick for macro context. Read the free posts first, pay monthly while you test, and keep only the letters you open every week.
