Elsewhere, S&P 500 constituents Henry Schein (HSIC 72.82, +4.06, +5.90%), Walgreens Boots Alliance (WBA 8.67, +0.44, +5.35%), and Moderna (MRNA 38.66, +1.81, +4.91%) pepper the top of the standings.

Meanwhile, recent spin-off Amentum Holdings (AMTM 22.91, -2.29, -9.09%) is continuing its fall to (albeit brief) all-time lows.
