Learn how Series 86 tests SEC filings, income statement, balance sheet, cash flow, segment reporting, guidance, risk factors, and source verification.
Series 86 expects the analyst to treat filings and financial statements as evidence, not as decoration around a research story. Forms 10-K, 10-Q, 8-K, proxy statements, earnings releases, investor presentations, and third-party data all need to be checked for purpose, reliability, timing, and consistency. The exam rewards answers that connect the income statement, balance sheet, cash flow statement, segment notes, guidance, and risk disclosures into one supportable view of the company.
This section is not only about finding numbers. It is about verifying whether the numbers support the thesis. A company may report strong sales growth while cash flow weakens, segment margins deteriorate, management guidance diverges from historical performance, or MD&A risk factors describe a problem that the headline release minimizes. Those inconsistencies matter because Series 86 expects the analyst to document key inputs and identify gaps before using the data in a model.
| Source | Strong Series 86 use | Common trap |
|---|---|---|
| Form 10-K | annual business, risk, segment, statement, and accounting-policy baseline | relying only on the earnings release |
| Form 10-Q | quarterly trend update and interim statement review | ignoring seasonal or one-time effects |
| Form 8-K | material events such as guidance changes, acquisitions, financing, or leadership changes | missing an event that changes the model |
| Proxy statement | governance, compensation, ownership, voting rights, and related-party signals | treating management incentives as irrelevant |
| Earnings release and call | management framing, KPIs, guidance, and near-term color | accepting non-GAAP framing without reconciliation |
| Third-party data | peer, industry, macro, channel, or consensus context | using it without checking source quality and definitions |
Series 86 questions often turn on statement linkages. The income statement shows profitability, but the balance sheet and cash flow statement test whether those profits are supported by assets, liabilities, working capital, and cash generation. A revenue increase is stronger when collections, inventory, margins, and operating cash flow support it. It is weaker when receivables surge, inventory builds, or free cash flow deteriorates without a defensible growth explanation.
Useful trend review normally includes:
The exam point is disciplined evidence. If a company’s guidance assumes margin expansion while the filings show cost inflation, lower utilization, or weaker mix, the analyst should flag the inconsistency rather than simply copy the guidance into the model.
Data verification protects the model from false precision. A strong analyst cross-checks filings, earnings materials, conference-call statements, industry data, and consensus estimates before treating an input as reliable. When the sources disagree, the analyst should identify the reason: different time periods, different definitions, different accounting treatment, stale data, or management adjustment choices.
Series 86 also expects repeatability. Key inputs, sources, and assumptions should be documented so the model can be updated after the next filing or earnings release. If a material data gap remains, the analyst should formulate targeted follow-up questions rather than burying the uncertainty in a forecast.
An analyst sees management guidance that assumes improving operating margins, but the latest 10-Q shows rising input costs, weaker segment margins, and no clear pricing offset. What is the strongest Series 86 response?
A. Use management guidance without adjustment because guidance is always more current than historical data B. Treat the inconsistency as a data-quality and assumption issue that must be investigated before finalizing the forecast C. Ignore segment margins because consolidated revenue is the only relevant input D. Assume the market has already priced in the issue and remove it from the model
Answer: B. Series 86 expects the analyst to verify source inputs and compare management assumptions with filing evidence before relying on them.
