Reported holders

Politicians whose newest complete holdings report lists this stock, or who reported buying it after that report (or at any time, if they have no usable report). A later full sale that could have closed the position removes them.

Prices are the market close on the purchase date; exact purchase prices are not disclosed. ROI is the percentage gain or loss from that price to the last close. Holders listed from a holdings report alone have no purchase date, so no price or ROI.
