Smart Analysis
Lennox International Inc (LII) · 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.

Lennox International Inc (LII) Detailed Analysis Report
Overall Assessment
This company scores 56/100 in our Smart Analysis, earning a C grade. Out of 10 metrics analyzed, 5 register as strengths (avg 9.0/10) while 5 fall into concern territory (avg 2.8/10). The category breakdown reveals uneven performance, with some areas requiring attention.
The Bull Case
The strongest argument centers on Return on Equity, Institutional Own., Market Cap. Valuation metrics including PEG Ratio (1.37) suggest the stock is attractively priced. Profitability is solid with Return on Equity at 75.80%, Profit Margin at 15.50%.
The Bear Case
The primary concerns are Revenue Growth, EPS Growth, Price/Book. Some valuation metrics including Price/Sales (3.22), Price/Book (14.27) suggest expensive pricing. Growth concerns include Revenue Growth at -11.20%, EPS Growth at -17.90%, which may limit upside. Profitability pressure is visible in Operating Margin at 19.80%.
Key Dynamics to Monitor
Three factors to monitor going forward. First, whether Revenue Growth improves, as this is the primary drag on the overall score. Second, margin trajectory, with Return on Equity at 75.80% currently healthy but needing to be sustained. Third, growth sustainability, with Revenue Growth at -11.20% needing to reaccelerate.
Risk Considerations
Based on the metric profile, this is a moderate-to-high risk investment. Strengths and concerns are roughly balanced. Investors should size positions according to their risk tolerance and maintain diversification.
Bottom Line
Mixed fundamentals with both positives (Return on Equity, Institutional Own.) and negatives (Revenue Growth, EPS Growth). A cautious approach is warranted. Monitor for improvement in weak areas before increasing conviction.
