Why is Caterpillar (CAT) stock moving?

Caterpillar's post-earnings slide has deepened. The Oct 29 report showed adjusted EPS of $7.20 and a record $78.1B backlog, but revenue of $20.68B narrowly missed and the full-year outlook was unchanged. The stock fell about 9% that day and has kept falling, from about $713 on Oct 28 to a close of $591.30 on Nov 4. Nov 4 was a 5.2% drop, on volume of 200.7K in the data provided, the second-highest in the window, and shares traded near $580 on Nov 5. Reported drivers include capacity limits, about $2.2B in annual tariff costs, dealer inventory reductions, and scrutiny of a roughly 50% valuation premium to peers. Several analysts cut price targets while mostly keeping their ratings, and the shares trade about 44% below the $1,073 high. Sentiment is also hurt by the stock's link to AI and data center spending. Supportive points are the backlog, a director's roughly $620K purchase, buybacks and dividends, and oversold readings that could invite a bounce. The trend is clearly negative, though, and the stock keeps setting new lows. A small after-hours gain on Nov 4 was erased by the Nov 5 weakness.
