GoldSignal research register
A running archive of the signals, ownership patterns, and market behaviors tested across a decade of public filings.
Most ideas do not survive. The ones that do become GoldSignal research signals.

SIG-030 SURVIVES
Flagship test
GoldSignal begins with public disclosures: insider transactions, major ownership filings, institutional positions, and strategic investments. Each potential pattern becomes a defined hypothesis. The rule is written down. Historical occurrences are identified. Forward returns are measured. Results are compared against a benchmark. Most hypotheses are weak, inconclusive, or fail entirely. That is expected. The purpose of the register is to preserve the entire research trail — not just the winners.
Public disclosure → testable rule → historical evidence. Not a marketing funnel.

One large shareholder may be wrong, affiliated, promotional, or acting for reasons unrelated to valuation. Two independent sophisticated investors crossing the same legally reportable ownership threshold is a different event. The hypothesis asks whether that convergence contains information.

In-sample held after audit. Out-of-sample not run. Not a recommendation.
A hypothesis survives when the pre-registered in-sample test held after audit. Survival is a recorded outcome on this register, not a promotion and not formal statistical validation. Out-of-sample confirmation has not been run. A survived test is not a recommendation.
“When two independent investors each become 10%+ owners of the same small mining company within 12 months, subsequent returns may differ from the broader junior-mining market.”
