MarketStack Index

Composite ranking · mass + velocity

Momentum-derived Index Score = Mass × 0.80 + Velocity × 0.20

Mass — Bestsellers durability

Durability of paid readership. Presence and rank in Substack's Bestsellers Top 100 over a 90-day rolling window, with exponential decay (τ = 30 days) so recent presence weighs more than old.

Velocity — Rising emergence

Recency of growth. Presence and rank in Substack's Rising Top 100 over a 42-day rolling window, with exponential decay (τ = 14 days) so recent rises dominate. Sort by Velocity to surface emerging voices.

How to read the table

Rows #1–100 are the MarketStack Index 100 (gold dot). Faded rows #101+ extend the ranking with writers in the top 100 by Mass or Velocity but outside the composite top 100.

Recommendation Index

Writers endorsed by the MarketStack Index 100 via Substack /recommendations

Methodology

Score = Σ_recommenders (101 − recommender_pos) / 100

Writers outside the MarketStack Index — smaller, less established — surfaced because the durably-paid Index 100 vouch for them. Each endorsement is weighted by the credibility of the recommender: a recommendation from MarketStack Index #1 contributes a full point; from #100, almost nothing. Authority flows along the recommendation graph. This is the second of MarketStack’s two complementary credibility lenses. The MarketStack Index measures who readers pay for, durably. The Recommendation Index measures who those proven writers vouch for.

BondStack

Fixed income voices on Substack

Rates StrategyGlobal Macro / RatesLiquidity & Capital FlowsMacro CreditCredit

The Framework

Fixed income is two markets — Rates and Credit — connected by two things: macro forces and liquidity.

Two Lenses

Every writer views these markets through a macro lens (what it means) or a market lens (how to trade it).

The Map

A 2×2 with two bridges: macro runs vertically, liquidity runs horizontally. Click a quadrant to jump in.

Macro Lenswhat the market means

Market Lenshow to price & trade it

Rates

Govt bonds
Yield curves

Global Macro / Rates

"What are bonds telling us about growth, inflation, policy?"

Macro writers anchored in the bond market. Treasuries as a read on the economy.

Rates Strategy

"Where are yields going? How do I position duration?"

Former rates strategists and desk traders. Curves, duration, central bank positioning.

Plumbing

The Bridge

Liquidity & Capital Flows

"Is there enough money? Where is it flowing?"

The plumbing that links rates and credit. Eurodollar mechanics, repo, funding markets, global monetary conditions. Spans both lenses because when liquidity moves, everything moves.

Credit

Corporate & sovereign
spreads & defaults

Macro Credit

"How is credit risk being priced across the cycle?"

Top-down credit. Sovereign debt, policy transmission, and how macro forces show up in spreads.

Credit

"Which names? Which sectors? Who defaults?"

Bottom-up credit. High yield, leveraged loans, distressed debt, restructuring and bankruptcy.

CLOStack

CLO voices on Substack

CLO-specific writing on Substack is very niche and fragmented—there's no single "CLO influencer" like in equities. Instead, CLO insights are scattered across structured credit specialists, private credit writers, and a few deep-dive blogs.

BiopharmaStack

Every roster author whose beat is biotech, pharma or healthcare equities — nine of 1,325, verified against their live feeds 22 Aug 2026

Positions & ValuationClinical CatalystsSmall-cap Single NamesM&A & Deal Flow

MSI is derived from Bestsellers and Rising rank history, so it measures leaderboard momentum rather than quality. Eight of these nine have never charted — their score sits at or near zero and the rank is a tiebreak, not a judgement. Only Back of the Napkin Bios carries real signal. The column inverts against output: The M&A Hunter publishes the most and ranks #412. None of the nine is graded in AlphaStack.

MacroStack

Macro voices on Substack — 43 writers, grouped by the lens they read the world through

The Map

43 macro voices, grouped by the lens they read the world through. Membership is measured, not curated: at least 25 macro posts making up 55%+ of everything the author publishes, active in the last two months, and either a top-500 MarketStack Index rank or 10k+ subscribers.

The Lenses

Global Macro splits three ways by how the writer works — Briefings (serial dated round-ups), Frameworks (method-led analysis) and Regimes (long-horizon narrative). The other three sections are the beat itself: geopolitics, policy and rates, or the data.

Daily Signals

Authors flashing unusual activity — refreshed with each data update ·

Signals surface authors showing statistically unusual activity on the Rising list — updated each time the daily data is refreshed. Each signal is scored across five cross-referenced dimensions. Multiple signals compound to determine signal rank. A single large spike from an unknown author scores lower than a moderate spike from a consistently tracked voice. The MarketStack Index rank acts as a credibility weight.

⚡ Spike — rank improved 50+ places in 1 day · 🆕 First appearance — never in top 100 before · 👋 Return — absent 7+ days, suddenly back · ★ Personal best — highest rank ever achieved · 📈 Above average — 25+ places better than own mean
