Advanced Ratio Analysis

This lesson provides an in-depth exploration of advanced ratio analysis, moving beyond basic calculations to uncover hidden trends and potential risks within financial statements. You will learn to leverage trend analysis, common-size analysis, and benchmarking techniques to gain a more complete understanding of a company's financial performance and position.

Learning Objectives

  • Apply trend analysis to identify patterns and potential issues in financial ratios over time.
  • Utilize common-size analysis to compare financial performance across different companies and periods, regardless of size.
  • Perform benchmarking against industry peers and competitors to assess a company's relative performance.
  • Evaluate the impact of different accounting methods on ratio comparability and interpret financial data accordingly.

Trend Analysis: Uncovering Time-Series Insights

Trend analysis involves examining a ratio's performance over several periods (e.g., years, quarters) to identify patterns, such as upward or downward trends, seasonality, or cyclical behavior. This helps uncover issues and opportunities.

Methodology: Calculate the ratio for multiple periods. Plot the ratio over time. Analyze the slope and direction of the trend. Identify inflection points (points where the trend changes direction).

Example: Imagine a company's debt-to-equity ratio has steadily increased over the past five years. This could indicate increasing financial risk, even if the absolute value of the ratio appears manageable in the latest period. Conversely, a declining days sales outstanding (DSO) trend could indicate improved efficiency in collecting receivables.

Important Consideration: Factor in external factors like economic conditions, industry dynamics, and major company events. A rising debt to equity ratio might be acceptable during a period of very low interest rates if the company is investing in profitable assets.

Common-Size Analysis: Leveling the Playing Field

Common-size analysis involves expressing financial statement items as percentages. On the income statement, each line item is expressed as a percentage of revenue (e.g., cost of goods sold as a percentage of sales). On the balance sheet, each item is expressed as a percentage of total assets or total liabilities and equity.

Benefits: Enables comparison between companies of different sizes or across different periods, eliminating the scale effect. Highlights relative performance and changes in financial structure.

Example: Two companies operate in the same industry, but one has significantly higher revenue. Comparing their operating margins directly might be misleading. Using a common-size income statement (showing each expense as a percentage of revenue) allows for a more accurate comparison of their profitability and cost management.

Important Consideration: Common-size analysis reveals proportions, but it doesn't reveal why the proportions have changed. Further investigation (e.g., cost driver analysis) is needed to understand the underlying causes.

Benchmarking: Comparing Apples to Apples (and Pears!)

Benchmarking involves comparing a company's financial ratios against those of its competitors, industry averages, or best-in-class companies. This helps assess relative performance and identify areas for improvement.

Types of Benchmarking:

  • Industry Benchmarking: Comparing against the average performance of companies within the same industry (e.g., using data from sources like IBISWorld or industry reports).
  • Competitor Benchmarking: Comparing against specific competitors. Requires access to competitor financial statements.
  • Best-in-Class Benchmarking: Comparing against companies that excel in a particular area, regardless of industry.

Considerations: Ensure comparability (e.g., similar business models, accounting methods, geographic locations). Consider any differences in the business. Understand the limitations of averages and peer groups.

Example: A company's gross profit margin is significantly lower than the industry average. Benchmarking can then pinpoint specific inefficiencies in the company's cost structure or pricing strategy.

Impact of Accounting Methods on Ratio Comparability

Different accounting methods can significantly impact the values of financial ratios, potentially hindering comparability. Understanding these differences is crucial for accurate interpretation.

Key Areas to Consider:

  • Inventory Valuation (FIFO, LIFO, Weighted Average): Affects cost of goods sold and thus gross profit and profitability ratios.
  • Depreciation Methods (Straight-line, Accelerated): Impacts net income and asset values.
  • Revenue Recognition (Percentage of Completion, Completed Contract): Affects revenue and thus profitability ratios.
  • Lease Accounting (Operating vs. Finance): Influences the balance sheet and leverage ratios.

Example: Two companies use different inventory valuation methods (FIFO and LIFO) during a period of rising prices. The company using LIFO will likely have a higher cost of goods sold and lower net income, which can affect its profitability ratios. Analysts need to adjust the ratios to allow a better comparison, or at the very least, understand the effect.
