Source-first guides to public filings and market records: what each dataset shows, when it updates, and what it cannot establish.
90 Days of Public Signals: What Changed in Congress, Insider, and Confluence Data
Looking back across roughly 90 days of Meridian's live pages: a senator's portfolio moved six times in a single week, a $60 million 10%-owner purchase landed in a niche energy fund, and one ticker briefly had four independent disclosure families pointing the same direction. None of it was secret — it was just scattered.
How to Evaluate Congress Stock Trackers in 2026
Evaluate a congressional trading tracker by reproducing a sample against primary disclosures. Vendor features and prices change; source traceability, date semantics, amendments, and coverage gaps matter more than static rankings.
Meridian Quick Start: A Source-First Research Workflow
Start with a research question, open the relevant source view, verify the original record and timestamp, then compare independent evidence. Meridian scores organize research; they do not predict returns or prescribe trades.
How to Read a Smart Money Confluence Score
A confluence score organizes available public signals into a research ranking. Read the source details, timestamps, conflicts, and missing inputs before the number. The score does not estimate returns or prescribe an investment action.
Institutional Disclosures vs Retail: What Public Records Can Show
“Smart money” is a media label, not proof of superior performance. Public records can support research when their scope, lag, provenance, amendments, and interpretation limits remain visible.
Using Smart-Money Signals in a Research Workflow
Public signals can prioritize research, but they do not determine a trade or portfolio allocation. A careful workflow verifies the source, compares independent evidence, adds business context, documents uncertainty, and keeps risk decisions outside the signal score.
Options Flow & Unusual Activity: How to Interpret the Record
Options records describe contracts and execution, not beneficial ownership or motive. Review spreads, rolls, event risk, liquidity, volatility, and delayed open interest before interpreting unusual activity.
What Is Dark Pool Trading? Records, Limits, and Common Misreadings
Dark pools are regulated non-displayed venues. Public trade reports and FINRA ATS aggregates have different timing and fields, and neither normally identifies the beneficial owner, motive, or future direction.
How to Read Meridian's Conviction Score
The Meridian Conviction Score ranks publicly reported signal records associated with a ticker. It is not intrinsic value, expected return, or an investor's stated conviction. Use it to open and verify the underlying evidence.
How to Read Berkshire Hathaway's 13F Filings
Berkshire Hathaway's 13F is a delayed snapshot of specified securities, not a live or complete portfolio. Tie each claim to the SEC filing, quarter, accession number, share class, and amendments.
Short Squeeze Research Guide 2026: Mechanics, Evidence, and Risks
A short squeeze is a market feedback loop, not a fixed screen. Short interest, days to cover, borrow conditions, float, liquidity, dilution, and catalysts are dated evidence with different limitations.
Congressional Stock-Trading Restrictions in 2026: Reading the Proposals
H.R. 7008 was introduced in January 2026 and reported by committee in February 2026. Reporting is not enactment; use Congress.gov for current status and avoid inferring motive or returns from delayed transaction disclosures.
Signal Confluence: Comparing Independent Public Disclosures
Signal confluence means several independently produced public records relate to the same ticker. It can help prioritize research, but source independence, provenance, and timing must be verified. Meridian's aggregate display is a ranking aid, not a return forecast or trading instruction.
