What Sectors Do Members of Congress Trade the Most?
Technology, by every count we ran. Of the 104 members of Congress with at least five disclosed stock trades in a sector-classified company, 55 trade technology more than any other sector, and the typical member’s record is 28.5% technology, followed by financials at 18.1%. That covers 18,686 trades disclosed through October 29, 2026, every parsed trade with a ticker whose company carries an SEC industry code.
Key numbers
- As of October 29, 2026, technology is the largest sector for 55 of the 104 members of Congress with five or more disclosed trades in a sector-classified company.
- Counting each of those 104 members equally, the average member’s disclosed trades are 28.5% technology and 18.1% financials (Coldpine, as of October 29, 2026).
- One household, Rohit Khanna (D-CA), accounts for 50.7% of the 18,686 sector-classified stock trades members of Congress have disclosed (Coldpine, as of October 29, 2026).
- Energy makes up 3.6% and defense and aerospace 1.4% of the average member’s disclosed trades, among 104 members with five or more sector-classified trades (as of October 29, 2026).
- The widest party gap is financials: 21.1% of the average Republican member’s disclosed trades against 13.7% for the average Democrat (62 Republicans and 41 Democrats with five or more sector-classified trades, as of October 29, 2026).
Every sector, three ways
The first column counts every member once: each member’s share of their own trades in the sector, averaged across the 104. The trade columns count disclosed lines, which lets the busiest filers set the order, so the last column repeats the count without the largest household. Each sector links to its page, with every ticker and member behind the number.
| Sector | Avg member share | Largest sector for | Members trading | Trades | Share of trades | Without largest household |
|---|---|---|---|---|---|---|
| Technology | 28.5% | 55 | 102 | 4,326 | 23.2% | 27.8% |
| Financials | 18.1% | 17 | 104 | 3,308 | 17.7% | 14.7% |
| Consumer Discretionary | 10.3% | 7 | 89 | 2,342 | 12.5% | 11.8% |
| Healthcare | 9.4% | 7 | 78 | 2,529 | 13.5% | 10.8% |
| Industrials | 8.4% | 5 | 76 | 2,092 | 11.2% | 11.9% |
| Communications | 6.8% | 6 | 79 | 744 | 4.0% | 4.4% |
| Materials | 4.2% | 2 | 59 | 1,128 | 6.0% | 4.8% |
| Utilities | 3.8% | 1 | 50 | 451 | 2.4% | 3.3% |
| Energy | 3.6% | 4 | 45 | 318 | 1.7% | 3.1% |
| Consumer Staples | 2.7% | 0 | 48 | 745 | 4.0% | 3.1% |
| Transportation | 2.6% | 0 | 51 | 515 | 2.8% | 2.6% |

One household is half the count
Rohit Khanna (D-CA) has disclosed 9,478 sector-classified trades, 50.7% of the 18,686 on file across 166 members. Any ranking by raw trade count is largely a ranking of that one household’s accounts. By trades, technology leads at 23.2% and financials follows at 17.7%. Without that household, technology is 27.8% of the remaining 9,208 and financials 14.7%.

Democrats and Republicans
Both parties put more of their trading in technology than anywhere else: 30.2% of the average Democrat’s record and 27.3% of the average Republican’s. The differences sit further down. The widest is financials, 21.1% for Republicans against 13.7% for Democrats; 53 of 62 Republicans and 30 of 41 Democrats traded it at all. Next is consumer discretionary, 13.0% for Democrats against 8.6% for Republicans. Then energy, 5.3% for Republicans against 1.0% for Democrats. Per-member shares keep one large filer from setting a party’s total; the party is the one on the member’s roster record.
| Sector | Democrats, avg share | Republicans, avg share | Democrats trading (41) | Republicans trading (62) |
|---|---|---|---|---|
| Technology | 30.2% | 27.3% | 37 | 48 |
| Financials | 13.7% | 21.1% | 30 | 53 |
| Consumer Discretionary | 13.0% | 8.6% | 31 | 45 |

| Agriculture | 0.5% | 0.0% | 3 | 2 |
Energy and defense are small
Coverage of congressional trading often turns to defense contractors and oil companies, because members vote on budgets and rules that reach them. In the disclosures they are a small slice: energy is 3.6% of the average member’s trades (318 trades by 45 members) and defense and aerospace 1.4% (138 trades by 34 members). A count says how often members trade a sector, not how large or how timely those trades were; each sector page lists the trades themselves, and for what stocks did between the trade and the disclosure, sector by sector, see What Stocks Do Before Congress Discloses.
Methodology and honest caveats
A trade counts here when it carries a ticker and that company has a coarse sector assigned from its SEC industry (SIC) code. That is 18,686 of 23,884 tickered trades (78.2%); funds, ETFs and companies without an SEC code fall outside every sector, and trades with no listed ticker are not counted. SIC groups are not a market-index classification, so a company can land somewhere a fund manager would not put it. The per-member frame includes the 104 members with five or more classified trades, each weighted equally; party columns cover Democrats and Republicans only. Trades are disclosed lines, purchases and sales together, across every year we have parsed. The sector counts match the sector pages, and how we parse and classify filings is set out in our methodology. For the individual stocks, see the most traded stocks in Congress. Figures are computed live and update as new filings arrive, so they may differ from the ones quoted the day this was published.
