Trades for Katherine M. Clark, newest filed first
Side	Ticker	The asset as filed, without the parts that repeat the row: a trailing “(TICKER)” that is the row's ticker, the stock code “[ST]” when it is the row's type (“Stocks (including ADRs)” in the House Clerk's list of asset type codes), and a trailing “Common Stock” or “Ordinary Shares”. Any other code is shown as its words from that list; a code not on it keeps its brackets. A name that differs from the filing in any other way is a button: its note gives the text as filed. The filing itself is the exact record. Filings under this member include transactions by spouse (SP), dependent children (DC), and joint accounts (JT) — the STOCK Act does not distinguish who directed a trade.

Profile

Tick = median of the 300 House members with disclosed rows in this build, one value per member, so a high-volume filer does not become the chamber. Describes the filing record, not intent.

median days between trade date and filing date, over rows that disclose both: +53dslower than chamber — median +28d
machine-readable transaction rows per distinct source filing: 10far above median — median 3.2
rows whose disclosed bracket tops out at $15,000: 90%small-lot profile — median 68%
purchases as a share of all disclosed rows — a count of disclosures, not of dollars: 47%≈ chamber — median 47%
rows with no spouse (SP), dependent-child (DC) or joint (JT) owner code — a row whose owner is not stated counts here too, so this is not a share of self-owned holdings: 49%more SP/DC/JT rows — median 97%

sum of statutory bucket bounds over the trailing 12 months — an interval, not an estimate of value: $225K–$550K
