What does Katherine M. Clark trade most?

Of the 420 disclosed trades on record, MRK appears most often — 5 disclosures. This counts disclosures, not position size.

Do members of Congress have to disclose their trades?

Yes. The STOCK Act requires a Periodic Transaction Report for most trades within 45 days. Reports state a dollar range, not an exact figure.

Does this show Katherine M. Clark's full net worth?

No. This page shows only stock trades disclosed under the STOCK Act — it excludes real estate, private businesses and most other assets. Many disclosures are a spouse's or dependent's account, not the member's own.

Which sectors appear most in Katherine M. Clark's disclosed trades?

Other / unclassified accounts for the largest share of disclosed trades, at 64% (268 of 420).

How current is this data?

Trades are disclosed after the fact — the STOCK Act allows up to 45 days between a trade and its public filing, so recent activity may not be reflected yet.

Read the disclosures themselves on the House Clerk's public disclosure site — Katherine M. Clark may have traded again since 14 July 2026.
