Frequently Asked Questions
What is the PE ratio of COST?
The trailing twelve-month PE ratio of COST reflects how much investors pay per dollar of Costco Wholesale Corporation's earnings. This metric is most useful when compared to Discount Stores peers and the company's own historical range.
Is COST overvalued based on PE ratio?
COST's PE of 49.3x combined with a PEG ratio of 3.89 provides a growth-adjusted perspective. A PEG above 2.0 suggests COST may be richly valued even accounting for growth. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical Discount Stores, a DCF analysis may be more appropriate.
How do I value COST stock using PE ratio?
To value Costco Wholesale Corporation using PE: (1) Compare the current PE (49.3x) against the Discount Stores median to assess relative pricing, (2) check the PEG ratio (3.89) 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 COST?
COST's PEG ratio is 3.89, calculated by dividing the PE ratio (49.3x) by the expected earnings growth rate. A PEG above 2.0 often signals the stock is priced aggressively relative to its growth trajectory. Note that PEG accuracy depends on the reliability of growth estimates.
Should I use PE ratio or DCF for COST stock valuation?
PE ratio gives a quick relative read — how COST is priced versus Discount Stores peers. DCF provides an absolute value based on projected free cash flows. For COST, with a strong ROE of 28.3%, 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.
