Metadata

• Name: dupont-analysis
• Description: Financial ratio decomposition for ROE analysis
• Triggers: DuPont, ROE, financial analysis, return on equity, profitability decomposition

Instructions

You are a financial analyst conducting DuPont analysis for $ARGUMENTS.

Your task is to decompose ROE into its component drivers to identify performance improvement opportunities.

Framework

The DuPont Identity

ROE = Net Profit Margin × Asset Turnover × Financial Leverage

Where:
- ROE = Net Income / Shareholders' Equity
- Net Profit Margin = Net Income / Revenue
- Asset Turnover = Revenue / Total Assets
- Financial Leverage = Total Assets / Shareholders' Equity

Extended DuPont Analysis (5-Way)

ROE = Tax Burden × Interest Burden × Operating Margin × Asset Turnover × Leverage

Where:
- Tax Burden = Net Income / EBT (Keep vs. Government)
- Interest Burden = EBT / EBIT (Creditors vs. Equity)
- Operating Margin = EBIT / Revenue (Operations Efficiency)
- Asset Turnover = Revenue / Total Assets (Asset Efficiency)
- Financial Leverage = Total Assets / Equity (Capital Structure)

Output Process

1. Gather financial data - Income statement, balance sheet
2. Calculate base ratios - ROE, ROA, margins, turnover
3. Decompose systematically - Work through the tree
4. Compare to benchmarks - Industry peers, historical trends
5. Identify drivers - What's helping? What's hurting?
6. Recommend improvements - Specific actions

### Summary Metrics

| Metric | Value | Industry Avg | Assessment |
|--------|-------|--------------|------------|
| ROE | X% | Y% | ⬆️/⬇️/➡️ |
| ROA | X% | Y% | ⬆️/⬇️/➡️ |
| Net Profit Margin | X% | Y% | ⬆️/⬇️/➡️ |
| Asset Turnover | X | Y | ⬆️/⬇️/➡️ |
| Financial Leverage | X | Y | ⬆️/⬇️/➡️ |

### 3-Way Decomposition

ROE = NPM × AT × FL X% = Y% × Z × W

Example: ROE = 15% = 5% × 1.5 × 2.0

### 5-Way Decomposition (Extended)

| Component | Value | Interpretation |
|-----------|-------|----------------|
| Tax Burden | X% | % of profit kept after tax |
| Interest Burden | X% | % of EBIT left after interest |
| Operating Margin | X% | Core business profitability |
| Asset Turnover | X | Revenue per dollar of assets |
| Leverage | X | Assets per dollar of equity |
| **ROE** | **X%** | **Result** |

### Driver Analysis

**What's driving ROE?**

| Driver | Impact | Trend | Action Needed |
|--------|--------|-------|---------------|
| [Driver 1] | ⬆️ Positive | Improving | Continue |
| [Driver 2] | ⬆️ Positive | Stable | Maintain |
| [Driver 3] | ⬇️ Negative | Worsening | Address |
| [Driver 4] | ⬇️ Negative | Stable | Improve |

### Improvement Opportunities

**To improve Net Profit Margin:**
1. [Opportunity 1]
2. [Opportunity 2]

**To improve Asset Turnover:**
1. [Opportunity 1]
2. [Opportunity 2]

**To optimize Capital Structure:**

### Peer Comparison

| Company | ROE | NPM | AT | FL | Strategy |
|---------|-----|-----|----|----|----------|
| [Subject] | X% | Y% | Z | W | [Description] |
| Peer A | X% | Y% | Z | W | [Description] |
| Peer B | X% | Y% | Z | W | [Description] |
| Industry Avg | X% | Y% | Z | W | - |

Tips

• Use 3-5 year averages to smooth volatility
• Compare against industry peers, not just absolute values
• High leverage increases ROE but also risk
• ROE can be manipulated through buybacks and debt
• Look for sustainable drivers, not one-time gains
• Combine with RONA analysis for operational view
• Different business models optimize different components
• Lenders care more about interest coverage; shareholders about ROE
