WASHINGTON—In an effort to revive her lagging capital gains, House Speaker Nancy Pelosi introduced a landmark piece of legislation Thursday that would appropriate federal funds to provide aid for her struggling personal stock portfolio. “This monumental bill will inject a much-needed and long-overdue stimulus, allowing my individual stock picks to reach their full potential,” said Pelosi, who remarked that America had to invest big in her private brokerage account now to ensure her frequent buying and selling of shares outperformed the market in the long term. “Without this measure, my equity investments will continue to be trapped in a cycle of disappointing compound annual growth rates. Being able to maximize the rate of return on my holdings is core to the American promise, and this bill delivers on that promise.” A press release issued by Pelosi’s office touted more than 30 of the speaker’s stock positions that would be lifted out of the red if the legislation were adopted.
