Based on our multi-factor framework, the stock trades at a fair valuation with a Smart Value Score of 60/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 49.0x, below its 5-year median of 54.1x. The PEG ratio of 5.68 indicates the price has run ahead of the underlying growth rate.
Looking at its own history, O is currently trading cheaper than 73% of the last 5Y on P/E. This places it in the 27th percentile of its historical range, a reasonable but unremarkable position.
Our discounted cash flow model estimates O's intrinsic value at $60.93 per share, against the current market price of $62.36. This implies a premium to fair value of -5.86%. The stock is priced close to its estimated fair value, offering limited upside without further operational improvement.
Financial quality is a concern. The Piotroski F-Score of 3/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: O trades at a fair valuation on our framework, with a Smart Value Score of 60/100. The valuation is defensible but offers no obvious bargain. Patience or a better entry price may reward disciplined buyers.
Frequently asked questions
Is O overvalued?
O scores 60/100 on our Smart Value Score (Grade C+), a mixed overall profile. On valuation specifically, the DCF puts intrinsic value below the current price, so the stock is expensive on cash flow today. The score reflects growth and quality carrying it, not a cheap entry point.
What is O's fair value?
Our DCF model estimates O's intrinsic value at $60.93 per share, versus the current price of $62.36, a margin of safety of -5.86%. Fair value is the present value of the cash flows we project the business to produce, so a price above it means the market is paying up for growth the model does not yet assume.
What P/E ratio does O trade at?
O trades at a P/E of 49.0x on trailing twelve-month earnings, against a 5-year median of 54.1x. P/E is what you pay per dollar of profit, and sitting below its own median means the stock is cheaper than usual relative to its earnings.
