Frequently Asked Questions
What is the PE ratio of CAT?
The trailing twelve-month PE ratio of CAT reflects how much investors pay per dollar of Caterpillar Inc.'s earnings. This metric is most useful when compared to Agricultural - Machinery peers and the company's own historical range.
Is CAT overvalued based on PE ratio?
CAT's PE of 39.8x combined with a PEG ratio of -18.66 provides a growth-adjusted perspective. CAT has negative earnings, so its PE and PEG ratios are not meaningful here and cannot tell you whether the stock is over or undervalued. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical Agricultural - Machinery, a DCF analysis may be more appropriate.
How do I value CAT stock using PE ratio?
To value Caterpillar Inc. using PE: (1) Compare the current PE (39.8x) against the Agricultural - Machinery median to assess relative pricing, (2) check the PEG ratio (-18.66) to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.
What is the PEG ratio of CAT?
CAT's PEG ratio is -18.66, calculated by dividing the PE ratio (39.8x) by the expected earnings growth rate. Because CAT has negative earnings, its PEG ratio is not meaningful and should not be read as a sign of under or overvaluation. Note that PEG accuracy depends on the reliability of growth estimates.
Should I use PE ratio or DCF for CAT stock valuation?
PE ratio gives a quick relative read — how CAT is priced versus Agricultural - Machinery peers. DCF provides an absolute value based on projected free cash flows. For CAT, with a strong ROE of 47.5%, both methods are worth using — PE for a market-relative check, DCF to stress-test whether fundamentals justify the price. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
