Explanation

Correct Answer: B

Financial ratios can indeed be affected by the phase of the business cycle. This is because:

1. Business Cycle Impact: During economic expansions, companies typically have higher revenues, better profitability, and improved liquidity ratios. During recessions, the opposite occurs - revenues decline, profitability suffers, and liquidity may become strained.

2. Examples of Affected Ratios:

   • Profitability ratios (like net profit margin, ROA, ROE) fluctuate with economic conditions
   • Liquidity ratios (current ratio, quick ratio) can be affected by changes in working capital needs
   • Activity ratios (inventory turnover, receivables turnover) vary with sales volume
   • Leverage ratios may appear different as earnings fluctuate

Why the other options are incorrect:

A. Each financial ratio is relevant to all industries. - This is false. Different industries have different financial characteristics and operating models. For example:

• Inventory turnover is crucial for retail/manufacturing but less relevant for service companies
• Debt-to-equity ratios vary significantly by industry (utilities vs. technology)
• Capital intensity affects asset turnover ratios

C. Aggregate financial ratios are useful for companies operating in different lines of business. - This is false. When a company operates in multiple business segments, aggregate ratios can be misleading because:

• They mask the performance of individual segments
• Different segments may have different optimal financial structures
• Segment-specific ratios provide more meaningful analysis

Key Takeaway: Financial ratio analysis requires understanding of industry norms, business cycles, and company-specific factors. Ratios should be compared with industry peers and considered in the context of economic conditions for meaningful interpretation.
