The problem
The precious metals sector is saturated with newsletters, promoters, and paid stock features. Most of what circulates is opinion wearing the costume of research. The people writing it are frequently compensated by the companies they cover.
Meanwhile the actual signal, what serious capital allocators are doing with their own money, is sitting in public filings that almost nobody reads because they are tedious, fragmented, and formatted for lawyers.
GoldSignal exists to close that gap. We read the filings so you can see the behavior.
Why I built GoldSignal
I've been investing in precious metals mining stocks since 2019. Over the years, I realized that some of the most valuable information in this sector is already public. The challenge is that it's scattered across thousands of regulatory filings and difficult to track consistently.
I work in data and systems, so I built the tool I wished existed. GoldSignal collects public filings, organizes them, and turns them into clear, searchable signals. Instead of spending hours reading SEC filings, insider reports, and fund disclosures, investors can understand what matters in seconds.
My background combines economics, data, and design. I hold a BS in International Business and Economics from the University of Findlay and an MS in Human-Computer Interaction from Iowa State University. That combination shaped the philosophy behind GoldSignal. The hard part is not collecting data. It is presenting complex information in a way that people can quickly understand and confidently use.
I also believe people deserve the opportunity to preserve the value of their work over time. Whether someone is saving for retirement, building a business, or supporting a family, years of effort represent something worth protecting. That belief led me to precious metals and ultimately to building GoldSignal.
The public GoldSignal data layer does not tell people what to buy. It gives everyone access to source-linked ownership evidence without countless hours spent reading regulatory filings. GoldSignal Pro is where I publish my own research portfolio and show how I apply that evidence. That is my research process, not individualized investment advice.
The goal is simple. Signal over noise.
What the public data layer publishes
Public evidence layer
- Verified insider transactions (Form 3, 4, 5) with date, side, share count, and value
- Institutional positions from 13F, 13D, and 13G filings
- Curated portfolios for tracked precious metals investors, hand maintained
- Gold Beta, an OLS regression of a stock's daily returns against gold, published with R-squared so you can judge the fit
- Company fundamentals and valuation measures from named market-data providers, cached, never guessed
- A direct link back to the underlying filing wherever one exists
What stays out of the data layer
- Sponsored coverage or paid company features
- Company-provided copy presented as independent research
- Guessed filing facts when the source is missing
- Hidden filing dates or stale ownership data presented as current
- "Exclusive" tips that cannot be traced back to evidence
If a filing fact appears in the public platform, we can point to where it came from. Pro is intentionally different: it is my research layer, where sourced evidence is combined with judgment, valuation work, portfolio construction, and scenario analysis. See GoldSignal Pro.
How the data moves
01
Ingest
SEC EDGAR filings are pulled on a schedule (Form 3, 4, 5, 13D, 13G, 13F), along with Canadian SEDI where covered. Market and company data come from Polygon.io (primary) with Financial Modeling Prep as a supplemental fill for thin OTC and Canadian names.
02
Normalize
Tickers are resolved to a single canonical symbol and exchange. Collisions and delistings are handled explicitly, not silently.
03
Validate
Rows are checked for completeness. Missing dates, sides, or share counts are rejected rather than estimated.
04
Cache
Everything is precomputed and written to cache. Pages read from cache, never from a live market-data API on page load.
05
Publish
The data appears in portfolios, stock pages, insider activity, and signals.

Architectural note: GoldSignal is cache-first by design. No page on this site makes a live market data call while you are waiting for it to load. This is why it is fast, and it is also why the data has a timestamp instead of a ticking clock.
Where the data comes from
| Filing | What it tells you | Cadence |
|---|---|---|
| Form 3 | Initial statement of beneficial ownership by an insider | On appointment |
| Form 4 | Insider buys and sells, with date, side, and share count | Within 2 business days of the transaction |
| Form 5 | Deferred or missed insider transactions | Annual |
| Schedule 13D | Active stake above 5 percent, with intent disclosed | Within 5 business days of crossing |
| Schedule 13G | Passive stake above 5 percent | Annual or on material change |
| Form 13F | Fund position above the reporting threshold, filed quarterly | 45 days after quarter end |
13F filings are backward looking by design. A quarterly holdings report tells you where a fund stood on the last day of the quarter, not where it stands today. We show the filing date alongside every position so the lag is visible instead of hidden.
Market data (primary)
Polygon.io
Primary feed for prices, market caps, betas, and historical series. Cached in the background; pages never call it live on load.
Market data (supplemental)
Financial Modeling Prep
Layered behind Polygon to fill company profile and fundamental fields when the primary feed is thin, especially OTC and Canadian-listed junior miners.
Why it matters
Sound money is not a trade. It is a position on how a society should treat the savings of the people who produce its wealth.
Currency debasement is a quiet transfer. It moves purchasing power from people who earn and save to institutions that print and borrow, and it does so without a vote, without a debate, and without a line item anyone has to defend. The people who take gold and silver seriously are, more often than not, taking that transfer seriously.
GoldSignal is built for that reader. Not the speculator chasing the next drill result, but the person who wants to see clearly, decide independently, and hold the consequences of their own judgment. The public data layer publishes sourced evidence because independence starts with facts. When I add judgment in Pro, I label it as research and show the evidence behind it.
Principles
Verifiable or absent
Every figure traces to a public document. If we cannot source it, we do not ship it.
No incentive to mislead
We take no money from covered companies. There is no sponsored tier and there never will be.
Show the uncertainty
Gold Beta ships with R-squared. Filing dates ship with positions. We surface the lag instead of burying it.
Separate evidence from judgment
The public data layer shows sourced evidence and transparent calculations. GoldSignal Pro is the separate research layer where Jon applies that evidence to his own portfolio.
FAQ
No. The public GoldSignal platform is an evidence layer built from public filings, insider disclosures, and named market-data providers. GoldSignal Pro separately shows Jon Binder's research process, model portfolio, valuation work, and scenario analysis. That is independent research and a record of how he applies the evidence, not individualized investment advice or a recommendation tailored to your circumstances.
