Understanding the Price-to-Earnings (P/E) Ratio
Worked Example: These Figures Today
The companies used as examples above, with the live figures behind them. Illustrations of the metric — not a ranking, not a shortlist, and not a recommendation.
| Ticker | Company | Price | Change | Market Cap | P/E | MoonshotScore |

P/E Ratio in Context: Examples
“Le MoonshotScore est une note transparente de 0 à 100. Les actions ordinaires cotées aux États-Unis sont notées par rapport à leurs pairs sectoriels selon cinq piliers — qualité de l'activité, solidité financière, valorisation, durabilité de la croissance et momentum — tandis que les ETF, les titres OTC et les valeurs étrangères utilisent un modèle hérité à neuf signaux. Il est conçu à des fins éducatives et pour une diligence raisonnable approfondie, et non comme un conseil financier.”
Questions worth resolving before acting on the screen
What does a high P/E ratio indicate?
A high P/E ratio may suggest that a stock is overvalued, or that investors anticipate higher earnings growth in the future. It's important to compare the P/E ratio to those of competitors and industry benchmarks.
What does a low P/E ratio indicate?
A low P/E ratio can suggest that a stock is undervalued, or that the market has low expectations for future earnings growth. However, it could also reflect underlying problems with the company.
What are the limitations of using the P/E ratio?
The P/E ratio does not provide a complete picture of a company's financial health. It should be used in conjunction with other financial metrics and qualitative factors. Also, negative earnings result in an undefined P/E ratio, making comparisons impossible.
