Two public signals, different clocks
13F filings show institutional holdings after the quarter ends. Insider filings can arrive much closer to the transaction date. That makes insider activity a useful companion signal, especially when a company is already appearing in fund portfolios.
The strongest cases are usually not one isolated purchase. They are patterns:
Multiple insiders buying in a short window.
Directors buying after a drawdown.
Insider buying near the same period that longterm funds are adding.
Why context still matters
Insider buying is not a verdict. Purchase size, compensation, liquidity, and the insider's prior behavior all matter. A small token buy from one director is different from a meaningful openmarket purchase by a founder or CFO.
FolioFact combines these public signals so readers can see the overlap quickly, then do the real work: valuation, business quality, and risk.
Direction matters more than the raw row
A holdings table is easiest to scan by current value, but the research signal often lives in the change columns. New buys, adds, trims, exits, and repeated accumulation tell different stories.
One useful screen is to sort for companies that appear in multiple funds' add columns in the same reporting period. That does not prove consensus is right. It does show that independent managers recently found the price or setup interesting enough to allocate capital.
What to check next
After a cluster appears, we usually check:
Whether the companies share a sector, factor, or theme.
Whether the buying is concentrated in specialists or spread across styles.
Whether company fundamentals changed before the filing window.
Whether insider buying supports or conflicts with the fund activity.
The goal is not to find a magic signal. The goal is to compress public filings into a better research queue.
The useful part of a delayed filing
Form 13F filings are delayed snapshots of public equity positions. They do not show a manager's live book, short exposure, cash, derivatives, or the reason a position exists. They are still useful because they turn a large universe into a smaller research queue.
Our first pass asks three questions:
Is this a new position, a steady accumulation, or a onequarter trade?
Is the position large enough to matter inside the fund's reported portfolio?
Do other highconviction funds show the same direction of travel?
The answer is not "buy what the fund bought." The answer is a ranked list of companies worth understanding better.
A better reading habit
Treat each filing as a prompt. A new topten position deserves different attention than a small basket holding. A doubled position means something different when the fund already owned it for years. A selldown can be tax management, portfolio construction, or a real thesis change.
FolioFact's job is to make those distinctions visible enough that the next click is obvious.
