Smart Analysis
Aon PLC (AON) · 10 metrics scored
Smart Score
Category Performance
WallStSmart pulls financial metrics like revenue growth, profit margins, and valuation ratios and scores each one from 0 to 10 based on how strong or weak it is. Those 10 scores are grouped into 4 categories: Growth, Profitability, Valuation, and Quality — which form the 4 axes of the spider chart you see. The categories are then combined into a final score out of 100, but not equally. Growth and Profitability together count for 60% of the total, because a fast-growing profitable business matters more than just a cheap one. That final number maps to a rating (Strong Buy, Buy, Hold, Avoid) and a letter grade, giving you one clear Stock Rating.

Aon PLC (AON) Detailed Analysis Report
Overall Assessment
This company scores 68/100 in our Smart Analysis, earning a B- grade. Out of 10 metrics analyzed, 6 register as strengths (avg 9.8/10) while 4 fall into concern territory (avg 3.0/10). The category breakdown reveals uneven performance, with some areas requiring attention.
The Bull Case
The strongest argument centers on Return on Equity, Operating Margin, EPS Growth. Profitability is solid with Return on Equity at 46.90%, Operating Margin at 31.40%, Profit Margin at 21.50%. Growth metrics are encouraging with EPS Growth at 138.30%.
The Bear Case
The primary concerns are Price/Book, Revenue Growth, PEG Ratio. Some valuation metrics including PEG Ratio (2.59), Price/Sales (4.02), Price/Book (7.46) suggest expensive pricing. Growth concerns include Revenue Growth at 3.70%, which may limit upside.
Key Dynamics to Monitor
Three factors to monitor going forward. First, whether Price/Book improves, as this is the primary drag on the overall score. Second, margin trajectory, with Return on Equity at 46.90% currently healthy but needing to be sustained. Third, growth sustainability, with Revenue Growth at 3.70% needing to reaccelerate.
Risk Considerations
Based on the metric profile, this is a moderate-to-high risk investment. The weight of evidence leans positive, with more strengths than concerns. Investors should size positions according to their risk tolerance and maintain diversification.
Bottom Line
Mixed fundamentals with both positives (Return on Equity, Operating Margin) and negatives (Price/Book, Revenue Growth). A cautious approach is warranted. Monitor for improvement in weak areas before increasing conviction.
