Data Verification and Analysis

Study how Series 86 tests company analysis, accounting quality, ratios, corporate actions, and the verification of industry and company data.

Function 2 is where collected information becomes usable research. Series 86 expects the analyst to read filings, verify the three financial statements, understand the business model, evaluate management execution, judge accounting quality, and compare key metrics against peers and industry drivers. This is the stage where unsupported stories should fail.

Read this chapter as the quality-control and interpretation layer. Start with filings and financial-statement trends, then move into business-model drivers, working capital and accounting practices, and capital-structure or corporate-action changes that can reset the research view.
