Mark DeSaulnier: No Disclosed Stock Trades

Mark DeSaulnier, the Democratic representative for California's 10th District, has no disclosed stock, bond, or fund transactions in Quantellect's data as of August 22, 2026. That is the entire story his trading data tells, and it is worth stating plainly rather than padding around: there is nothing to analyze in terms of buys, sells, sector tilts, or timing, because no disclosed transactions are present for this member.

DeSaulnier is not an outlier in that respect. Among the 537 sitting members of Congress tracked as of August 22, 2026, 276 have no disclosed trades on file, including 237 of the chamber's 437 sitting House members. That means a majority-adjacent share of the House currently shows the same blank slate DeSaulnier does. In raw-count terms, members without disclosed trades form a substantial part of both the full congressional population and the House cohort represented in the data.

How Congressional Transaction Disclosure Works

Members of Congress are required under the Stop Trading on Congressional Knowledge Act of 2012 to report covered securities transactions exceeding $1,000 by the earlier of 30 days after becoming aware of the transaction or 45 days after the transaction date. Those filings, known as Periodic Transaction Reports, are the raw material behind the transaction profiles on this site. The House Committee on Ethics financial disclosure instruction guide identifies transactions excluded from PTRs, including transactions involving real property, purchases or sales of excepted investment funds, mutual fund or ETF transactions, and transactions solely among the filer, spouse, or dependent children.

It is also worth being precise about attribution mechanics generally, even in a case like this where there is nothing to attribute. When transaction data is present, Quantellect distinguishes among self, spouse, joint, dependent-child, and unknown attribution. That field determines how each disclosed transaction is described: a spouse or dependent-child transaction remains associated with the member's disclosure record but is not presented as the member's personal trade. DeSaulnier's data contains no transactions in any of those attribution categories.

Score Coverage

As of the latest published scoring date, August 21, 2026, 76 members of Congress carry a trading score, 73 of whom are currently sitting. DeSaulnier is not among them. No score row exists for this member at that date, so this profile presents no rating, tier, or cohort ranking. Each of those score fields is absent rather than estimated or inferred from the zero-transaction record.

For investors using this page as a reference, the practical takeaway is narrow. There is no activity to characterize, no sector concentration to describe, no notable purchase or sale to contextualize, and no basis for comparing disclosed trading behavior over time, because the transaction history contains no annual activity entries. A future Periodic Transaction Report could introduce specific transaction information, including dates, transaction types, attribution, securities, and sectors, for later coverage, but none of those details exists in the current data.

Disclosure and Data Notes

This profile is built from congressional financial disclosure filings as processed and structured by Quantellect. A zero transaction count means Quantellect's dataset contains no disclosed transaction rows for DeSaulnier; it does not establish that no financial disclosure filings exist or that the member has no financial assets or other financial activity. Periodic Transaction Reports cover a defined category of reportable transactions and do not provide a complete accounting of a member's finances. Figures, dates, and counts on this page are drawn directly from the underlying disclosure data and are not estimated, projected, or inferred. The absence of a score row is likewise a data-coverage state, not a judgment about the member's financial conduct.
