Every panel here is built from SEC Form 4/4A filings — the disclosure an
officer, director, or 10% owner must file within two business days of trading their own
company's stock. Only open-market buys (code P) and sells (code S) are included;
option exercises, grants, and other compensation mechanics are excluded. Dates are
filing dates — the day the information became public, not the day the
insider traded.
Disclosed insider trades per date
The timeline. One bar per calendar date, stacked green (buys) over red (sells), counting
disclosures that became public that day. Click a bar to load that day into the two panels
below.
Trades disclosed this day
That day's disclosures grouped by side and by the role the filer holds. A filer who is both
an officer and a director appears in both role rows, so the rows overlap and can sum past the
day's total — the header line carries the true totals.
Top trades by notional
The individual disclosures, largest first. Notional is the dollar size of the
trade — shares × price per share, as reported. Click any row for its full detail: shares,
implied average price, the filer's roles, the company's industry, and whether it was a
pre-scheduled 10b5-1 plan trade (which historically carries far less
information than an opportunistic trade).
Most impacted companies / industries — under Advanced Analytics
A market-model event study. For each company that disclosed a trade, we estimate its beta
against the market over the prior 60 trading days, then measure the abnormal
return (CAR) over the next N days — the part of the move its beta does not explain.
The industry table runs the identical study on equal-weighted FF48 industry indices. ✓ marks
p < 0.05. These are observational event studies, not a tradable backtest.
Susceptibility studies — under Advanced Analytics
Standing research results covering 2019–2024, independent of the day you selected: which
industries and which individual companies move most in response to their insiders' disclosed
trades. Company susceptibility is concentrated in small caps; the industry effect is weak but
consistently positive across most of the 48 industries.
Known limits
About 43% of disclosure rows have no resolvable CIK (delisted or non-standard tickers);
they appear in the trade lists but are excluded from the event studies and reported as
unmatched. Price coverage skews toward larger, currently-listed names.
