This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.

Looking at its own history, AES is currently trading more expensive than 50% of the last 5Y on P/E. This places it in the 50th percentile of its historical range, a reasonable but unremarkable position.
Our discounted cash flow model estimates AES's intrinsic value at $18.13 per share, against the current market price of $14.45. This implies a margin of safety of +9.32%. 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 2/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
