The integrated reading of the income statement, balance sheet, and cash flow statement as a connected system — the foundation of all fundamental analysis.
“Security analysis demands a thorough examination of the financial statements — not just the earnings per share, but the balance sheet strength that supports those earnings and the cash generation that validates them. — Benjamin Graham”

Deeper Explanation
The three financial statements are mechanically linked and must be read together to understand a business accurately. The income statement reports what the business earned on an accrual basis during the period. The cash flow statement reconciles that reported profit to actual cash received and spent — the critical check on whether reported earnings are real. The balance sheet shows the cumulative effect of all prior periods and the current financial position. The most important cross-statement check is the cash conversion ratio: operating cash flow divided by net profit. For a healthy business this ratio should be close to 1.0. A sustained gap between reported profit and operating cash flow — where profit is high but cash generation is low — is the first quantitative signal that revenue recognition may be aggressive or that the business is consuming cash to grow that the income statement is not showing. Investors who read only the income statement are reading one-third of the story.
