Palanor calculation from licensed closes. Members are the U.S.-listed companies where the stake is in the listed company itself; each enters at the close of its announcement date, so the announcement-day move is left out. Price only, no dividends. Not the value of the government’s holdings.
How the shares of listed companies in which the U.S. government took an equity stake have done since the stakes were announced, next to the S&P 500. The basket is small and leans on semiconductors, quantum computing and critical minerals, so it swings far more than the market.
