Valuation Metrics
Valuation metrics compare stock price to fundamental measures like earnings, sales, or book value. They help determine whether a stock is cheap, fairly valued, or expensive relative to what the company produces.
Price-to-earnings (P/E) ratio divides stock price by earnings per share. Price-to-sales (P/S) compares price to revenue. Price-to-book (P/B) relates price to balance sheet equity. Each offers different perspective on value.
Profitability Metrics
Profitability metrics measure how effectively a company generates profits from operations and capital. Return on equity (ROE) shows profit generated from shareholder investment. Return on assets (ROA) measures profit from total assets.
Profit margins—gross, operating, and net—show profitability at different levels. Higher margins indicate pricing power and efficiency. Compare margins to industry peers and track trends over time to assess competitive position.
Return on Invested Capital
ROIC measures return on all capital—both debt and equity. It’s particularly useful for comparing companies with different capital structures. ROIC exceeding cost of capital indicates value creation; below cost destroys value.
Efficiency Metrics
Efficiency metrics reveal how well management uses company resources. Asset turnover (revenue/assets) shows sales generated per dollar of assets. Inventory turnover indicates how quickly inventory sells. Receivables turnover measures collection speed.
The cash conversion cycle—days inventory outstanding plus days sales outstanding minus days payables outstanding—shows how long cash is tied up in operations. Shorter cycles mean better working capital management.
Leverage Metrics
Leverage metrics assess financial risk from debt. Debt-to-equity ratio shows borrowing relative to shareholder investment. Interest coverage (operating income/interest expense) indicates ability to service debt. Net debt/EBITDA measures payback capacity.
Higher leverage amplifies returns—both positive and negative. Low-leverage companies can weather downturns; high-leverage companies may face distress. Match leverage to business stability—cyclical businesses need lower debt.
Frequently Asked Questions
Which metrics matter most?
The most important metrics depend on your investment style and the company type. Value investors focus on valuation ratios, growth investors on revenue and earnings growth, and quality investors on ROE and margins. Use multiple metrics for complete analysis.
How do I know if a metric is good or bad?
Context is everything. Compare to industry peers—a 10% margin may be excellent in one industry and poor in another. Compare to historical averages for the same company. Understand what drives the metric and whether current levels are sustainable.
Can metrics be misleading?
Absolutely. One-time items distort single-period metrics. Accounting choices affect reported numbers. Different business models make comparisons difficult. Always understand the underlying business and verify metrics with multiple data points.
Where do I find these metrics?
Financial websites like Yahoo Finance, Morningstar, and Seeking Alpha display common metrics. For accuracy, calculate key ratios yourself from financial statements. Different sources may calculate ratios differently, causing confusion.
