| 2023-10-24 | Greg Stanton · D-AZ-04 · House | SellComment: In Sept. 2023, my wife started with a new investment firm for her assets, and this new investment firm was unaware of our policy against owning individual stocks. On Sept. 26, the new investment firm purchased stock mimicking the S & P 500. I learned of the purchase of stock on Oct. 21, and immediately on the next business day (Oct. 23) requested the stocks be divested. The new investment firm sold the stock and instead invested in Exchange Traded Funds. | $1k – $15k | Spouse | 2023-11-09 · 16d | PTR |

What do these records cover?
House trades come from the official House Clerk filings from 2021 on; earlier House rows come from an archive of the same reports. Senate trades come from an archive that ends on Nov 30, 2020. Senators’ LRCX trades after that date are not included until the Senate eFD import is live, so this page undercounts Senate activity since then (7 of the 68 trades here are Senate filings). Scanned paper filings are not itemised, so their trades are not counted.
These are trades reported on periodic transaction reports, not current holdings: a member who bought LRCX may have sold it since, and a position bought before the records start, or held through a fund, does not show here. Amounts are disclosed as bands. This page is educational and is not a recommendation to buy or sell LRCX.
