Learn how Series 86 tests business strategy, revenue drivers, cost structure, management execution, supply chain, customer concentration, product mix, and competitive position.
Series 86 expects a research analyst to understand how the company actually makes money. A financial statement trend is more useful when it is connected to the business model: what the company sells, how demand is generated, what costs are fixed or variable, how contracts work, whether customers are concentrated, and whether management has the capacity to execute the stated plan.
This section is the operating-driver bridge between statement review and forecasting. The analyst identifies the measurable drivers that will later feed revenue, margin, working-capital, capex, and valuation assumptions. A candidate who can describe the company but cannot translate the description into drivers is not yet doing Series 86 analysis.
| Area | Strong analyst question | Why it matters for Series 86 |
|---|---|---|
| Strategy and business plan | Is management’s plan supported by execution evidence? | separates realistic forecasts from unsupported narratives |
| Revenue drivers | Are sales driven by volume, price, mix, customer growth, or retention? | determines the correct forecast inputs |
| Cost structure | Which costs are fixed, variable, discretionary, or input-sensitive? | explains operating leverage and downside risk |
| Contracts | Are revenues recurring, usage-based, long term, or take-or-pay? | affects revenue visibility and risk |
| Supply chain | Which suppliers, inputs, or logistics constraints matter? | identifies cost and availability risks |
| Customer concentration | How much depends on a few customers or channels? | exposes fragility hidden by aggregate growth |
Series 86 does not reward vague praise for management. The analyst should evaluate execution using evidence: prior guidance accuracy, capital allocation, product launches, acquisition integration, cost control, incentive alignment, and the ability to respond to changed market conditions. Management quality is strongest when the record supports the plan and the incentives are consistent with shareholder value.
The exam may present a company with attractive strategic claims but weak evidence. If management promises margin expansion, the analyst should look for pricing power, scale benefits, product mix improvement, cost savings, or utilization gains that can support the claim. If management promises growth, the analyst should check capacity, capex, demand, supply chain, and customer acquisition economics.
A Series 86 answer is usually strongest when it converts qualitative evidence into measurable drivers. For example:
The point is not to memorize every industry metric. It is to choose the drivers that actually explain the company’s economics.
Business-model analysis also requires peer and industry context. A company with strong differentiation, switching costs, network effects, or a durable cost advantage may support better pricing and margins than peers. A company exposed to substitutes, customer concentration, weak product relevance, or a disruptive competitor may require lower growth, lower margins, or higher risk assumptions.
Series 86 often tests the candidate’s ability to avoid headline bias. High revenue growth is not automatically strong if customer acquisition costs are rising faster, customer churn is increasing, or the growth depends on discounts. Slower growth is not automatically weak if margins, cash conversion, and competitive durability are superior.
A company’s revenue is growing quickly, but customer acquisition costs are rising, churn is increasing, and management has repeatedly missed prior profitability guidance. What is the strongest Series 86 response?
A. Treat the revenue growth as sufficient evidence of business quality B. Increase the valuation multiple because fast growth always outweighs operating risk C. Reassess the sustainability and profitability of the growth before relying on management’s plan D. Ignore management’s execution record because only current-period results matter
Answer: C. Series 86 expects the analyst to connect operating drivers and management execution to the forecast rather than relying on headline growth alone.
