Financial Ratios
Financial ratios allow investment advisers to analyze and compare companies. By expressing financial data as ratios, advisers can evaluate liquidity, leverage, profitability, and valuation regardless of company size.
Why Ratios Matter
Ratios provide:
- Comparability — Compare companies of different sizes
- Trend Analysis — Track changes over time
- Benchmarking — Compare against industry standards
- Quick Assessment — Summarize complex financials
Liquidity Ratios
Liquidity ratios measure a company's ability to pay short-term obligations. They're particularly important for creditors and for assessing near-term financial health.
Current Ratio
| Formula | What It Measures |
|---|---|
| Current Assets / Current Liabilities | Ability to pay short-term debts with short-term assets |
Interpretation:
| Current Ratio | Meaning |
|---|---|
| > 1.0 | Company has more current assets than current liabilities |
| < 1.0 | Company may struggle to pay short-term obligations |
| 2.0 | Often considered healthy (depends on industry) |
Example: Current assets of $500,000 / Current liabilities of $250,000 = 2.0
Quick Ratio (Acid-Test Ratio)
| Formula | What It Measures |
|---|---|
| (Current Assets − Inventory) / Current Liabilities | Ability to pay short-term debts with liquid assets only |
Why Exclude Inventory?
- Inventory may not sell quickly
- Inventory value may decline
- More conservative measure than current ratio
Interpretation:
| Quick Ratio | Meaning |
|---|---|
| > 1.0 | Can pay current liabilities without selling inventory |
| < 1.0 | May need to sell inventory or borrow to pay obligations |
Example: (Current assets $500,000 − Inventory $150,000) / Current liabilities $250,000 = 1.4
Leverage (Solvency) Ratios
Leverage ratios measure long-term solvency and how much debt a company uses in its capital structure.
Debt-to-Equity Ratio
| Formula | What It Measures |
|---|---|
| Total Liabilities / Shareholders' Equity | How much debt vs. equity finances the company |
Interpretation:
| D/E Ratio | Meaning |
|---|---|
| < 1.0 | More equity than debt financing |
| > 1.0 | More debt than equity financing |
| > 2.0 | Highly leveraged; higher financial risk |
Industry Context: Capital-intensive industries (utilities, manufacturing) typically have higher D/E ratios than service industries.
Debt Ratio
| Formula | What It Measures |
|---|---|
| Total Liabilities / Total Assets | Percentage of assets financed by debt |
Example: Total liabilities $400,000 / Total assets $1,000,000 = 40% debt ratio
Valuation Ratios
Valuation ratios help determine whether a stock is overvalued or undervalued relative to its earnings, growth, or assets.
Price-to-Earnings (P/E) Ratio
| Formula | What It Measures |
|---|---|
| Stock Price / Earnings Per Share (EPS) | How much investors pay per dollar of earnings |
Interpretation:
| P/E Range | Typical Meaning |
|---|---|
| < 15 | May indicate undervalued or slower growth |
| 15-25 | Typical range for many stocks |
| > 25 | Premium valuation; high growth expected |
Two Types:
- Trailing P/E — Uses past 12 months earnings
- Forward P/E — Uses projected future earnings
PEG Ratio (Price/Earnings-to-Growth)
| Formula | What It Measures |
|---|---|
| P/E Ratio / Expected EPS Growth Rate | P/E relative to growth rate |
Why It's Useful: Accounts for growth—a high P/E may be justified if growth is high.
| PEG Ratio | Interpretation |
|---|---|
| < 1.0 | Potentially undervalued relative to growth |
| = 1.0 | P/E justified by growth rate |
| > 1.0 | Potentially overvalued relative to growth |
Price-to-Book (P/B) Ratio
| Formula | What It Measures |
|---|---|
| Stock Price / Book Value Per Share | Price relative to accounting value |
Book Value = Total Assets − Total Liabilities (shareholders' equity)
Interpretation:
| P/B Ratio | Meaning |
|---|---|
| < 1.0 | Stock trades below accounting value (potential value opportunity) |
| = 1.0 | Stock trades at book value |
| > 1.0 | Premium to book value (market expects future growth) |
Profitability Ratios
Return on Equity (ROE)
| Formula | What It Measures |
|---|---|
| Net Income / Shareholders' Equity | Return generated on shareholders' investment |
Example: Net income $100,000 / Equity $500,000 = 20% ROE
Profit Margin
| Formula | What It Measures |
|---|---|
| Net Income / Revenue | Percentage of revenue that becomes profit |
Example: Net income $50,000 / Revenue $500,000 = 10% profit margin
Comparing Liquidity Ratios
| Ratio | Formula | Includes Inventory? | More Conservative? |
|---|---|---|---|
| Current Ratio | Current Assets / Current Liabilities | Yes | No |
| Quick Ratio | (Current Assets - Inventory) / Current Liabilities | No | Yes |
In Practice: How Investment Advisers Apply This
Analyzing a potential investment:
- Compare ratios to industry peers
- Look at trends over 3-5 years
- Consider the company's business model
- Don't rely on a single ratio—use multiple
Red Flags:
- Declining liquidity ratios
- Rapidly increasing debt-to-equity
- P/E much higher than peers without justification
- ROE declining over time
On the Exam
The Series 65 exam tests your ability to:
- Calculate current ratio, quick ratio, and debt-to-equity
- Interpret what ratios indicate about financial health
- Distinguish between liquidity and leverage ratios
- Understand valuation ratios (P/E, PEG, P/B)
- Compare current ratio vs. quick ratio
Expect 2-3 questions on financial ratios. Common formats include calculating a ratio from given data or interpreting what a ratio indicates.
Key Takeaways
- Current Ratio = Current Assets / Current Liabilities (includes inventory)
- Quick Ratio = (Current Assets - Inventory) / Current Liabilities (excludes inventory)
- Debt-to-Equity = Total Liabilities / Shareholders' Equity
- Quick ratio is more conservative than current ratio
- P/E ratio shows how much investors pay per dollar of earnings
- PEG ratio adjusts P/E for growth rate (< 1.0 may indicate undervaluation)
- Compare ratios to industry peers and historical trends
- No single ratio tells the complete story—use multiple ratios together
What is the formula for the current ratio?
The quick ratio differs from the current ratio because the quick ratio:
A company has a PEG ratio of 0.8. This suggests the stock may be:
2.5 Time Value of Money
