A top official at President Trump's Department of Homeland Security recently put some of his money in an exchange-traded fund (ETF) built to mimic the portfolios of congressional Democrats, according to a financial disclosure. Under Secretary for Science and Technology Pedro Allende purchased between $15,000 and $50,000 in shares of a Subversive ETFs product called NANC (NANC) (named after Nancy Pelosi) that tracks the trading of Democratic lawmakers and invites traders to "invest like the oligarchy." "It's a validation of what we're doing," said Dan Weiskopf, co-portfolio manager of the NANC fund and another ETF that mirrors Republican portfolios. Pedro Allende, the Homeland Security undersecretary for the Science and Technology Directorate, testifies during an oversight hearing on Capitol Hill in January. The fund mirrors trades by Democratic lawmakers and is heavily focused on technology stocks.
