Showing the 20 most recent disclosures. Lines for the same asset, day, band and action are shown once and marked with the number of lines. All of Katherine M. Clark's trades in the browser, every line of every report.

Under each figure: the S&P 500 over the same window, and the gap between the stock and the index in percentage points. A disclosure carries a band, not a fill. After a sale the stock's move keeps its sign, so a positive number means the stock kept rising after the sale. An option row carries the underlying stock's move, not the option's value. Where a ticker stopped trading the row says when its price history ends; where the company trades on under a new ticker the figure is priced under that one. Estimates; n/a where we hold no figure for the row.

Every figure is an estimate built from the ranges on the member's financial disclosure reports, marked by the price movement of each stock since the filing; the share is of the whole estimated portfolio, small positions included. These are the stock and fund positions the model prices; the net worth estimate above also counts other disclosed assets and subtracts liabilities.

Disclosed volume per year the member traded, 2014 to 2026. A filing gives a range, not an amount, so each bar sums the midpoints of the ranges disclosed that year: a $1,001 to $15,000 line counts as $8,000. The sale side also counts exchanges, including shares received in a spin-off or merger.

Questions

How many stock trades has Katherine M. Clark disclosed?

Katherine M. Clark has disclosed 785 transactions under the STOCK Act. This page lists the 20 most recent, covering Apr 8, 2022 to Jun 16, 2026.

How long does Katherine M. Clark take to report a trade?

For trades made from Jan 2014 to Jun 2026, the median gap between a trade and its disclosure is 53 days. The STOCK Act allows up to 45.

Which accounts do Katherine M. Clark's disclosures name?

Of the 20 disclosures shown, 1 names a joint account. 19 do not name an account. The account is whatever the filer wrote on the disclosure; a spouse's or a joint account is disclosed under the member's name, as the STOCK Act requires.

Where does the estimated net worth on this page come from?

A model's estimate, not a figure the member filed. Reports give every asset and debt as a range, so the model takes a value inside each range, subtracts debts and prices the stocks it tracks at the latest close we hold. We round it because the top range has no upper limit. It covers only what the reports carry and is not a measure of anyone's wealth. The methodology page sets out how it is built and what it leaves out.

How have the stocks moved since Katherine M. Clark's trades?

Across the 4 priced rows shown, the median stock move from the trade date to the latest close we hold (figures as of Oct 26, 2026) is +12.7%. That figure is an estimate describing the stock after each trade, not the member's result: a disclosure carries a band, not a fill, a sale keeps the same sign, and an option row carries the underlying stock's move. 16 of the rows shown have no figure in our data.

How to read a STOCK Act filing

WHAT THE FILING ACTUALLY SAYS

$A range, not an amount. Members disclose a band such as $1,001 to $15,000. The band is the filing, and we do not narrow it.
45Up to 45 days after the trade, lawfully. The delay column counts calendar days from the transaction to its publication. Inside 45 days is within the law.
OPAn option names the underlying. A contract on a company is described using that company's name, so it can read like a share purchase. Those rows say otherwise.

A disclosure is a record of a transaction, not evidence of anything else, and nothing here is investment advice. Sourcing and the limits of this data are on the methodology page. How these reports work is explained in our guide to STOCK Act reports.

Data as of Oct 26, 2026.
