Caterpillar Inc. (NYSE: CAT) ended Thursday’s session on a steady note and barely moved after the closing bell—an important detail for investors watching whether this week’s sharp volatility is stabilizing heading into Friday, December 19.

As of 5:28 p.m. ET, CAT traded at $566.22 in after-hours, up $0.39 (+0.07%) from the regular-session close. The stock closed at $565.83, up $3.94 (+0.70%) on the day. ^[1]

That modest rebound matters because it follows a rough mid-December stretch for the Dow component—CAT is still coming off a -4.59% slide on Dec. 17 and remains meaningfully below last week’s highs. ^[2]
