U.S. stocks were on course to pare back some of their recent losses Thursday, while Treasury yields were holding firm after a weak 20-year bond auction rattled investors during the previous trading session. S&P 500 futures ticked up 0.1%, and contracts tied to the tech-heavy Nasdaq 100 climbed by the same amount. Investors are worried that the Trump administration’s signature tax and spending bill could be bad news for the economy, particularly after Moody’s took away its triple-A rating on U.S. debt.
