Why Did Caterpillar Stock Fall?

For questions about this article or underlying research, email help@trefis.com.

Shares of Caterpillar (CAT) fell 9.3% on Thursday, October 29, 2026, against a 0.3% slip for the S&P 500. The decline occurred on the same day Caterpillar released third-quarter results that beat adjusted earnings per share estimates but fell slightly short on revenue. So what in the report sent the stock down?

Caterpillar Expects Moderate Sales Growth In Q4 2026

News reports linked the decline to Caterpillar’s sales outlook for the fourth quarter of 2026. Management said it anticipates “moderate sales growth versus the prior year” for the company as a whole. By segment, it expects strong growth for Resource Industries, moderate growth for Power and Energy, and sales similar to a year earlier for Construction Industries. Management said the Power and Energy segment faces comparisons to a strong fourth quarter of 2025 as it continues to ramp capacity. According to news reports that day, the stock had been priced for a raise, and the moderate sales outlook overshadowed the earnings beat.

A share price that assumes faster growth is exposed when sales do not keep pace with it. Tesla, for example, is still valued at about 12 times sales even though its deliveries fell two years in a row. Read Trefis Big Story: How Tesla Blundered.

Caterpillar delivered a quarter stronger on profit than on sales. Adjusted earnings per share reached $7.20, topping the $7.06 estimate, while revenue of $20.68 billion landed just under the expected $20.76 billion. Management said sales and revenues rose 17% from a year earlier, driven by strong end market demand.

The company also continued to build its order book. The backlog of orders Caterpillar has taken but not yet delivered climbed 96% from a year earlier, reaching a record $78 billion.

Did Caterpillar Fall Alone Or With Peer Stocks?

Caterpillar fell on its own, not with its broader sector. XLI, the fund that tracks the industrials sector, gained 1.0% during the same session. Across the company’s Trefis peer list, Deere rose 3.0% and Terex advanced 6.0%, while PACCAR, Cummins and Oshkosh fell by far less than Caterpillar did. News reports named the Caterpillar and Alphabet results as the two earnings reports pulling the S&P 500 lower that day.

Where Does Caterpillar Stock Stand After The Drop?

Caterpillar stock had not suffered a one-day decline of this magnitude in the prior 365 days. The last move of this size in either direction was a 9.9% advance on April 30, 2026.

Investors who bought Caterpillar a year ago remain ahead, with the stock returning 24.5% over the past 12 months compared to a 13.3% gain for the S&P 500. That return runs from the October 28, 2025 close, just before the 52-week range below begins. The shares closed at a 52-week high of $1,064.90 on June 30, 2026, and have slid since to finish about 39% below that peak at the latest close. From July 31 to October 29, the stock lost 20.4%, while the S&P 500 gained 3.3%. On October 29, the stock closed at $647.39, compared to a 52-week low of $546.13 set on November 20, 2025.

Caterpillar will next report its fourth-quarter 2026 results. Sales growth against the fourth quarter of 2025 is the number to watch in that report.
