Financial Analyst Skill
Overview
Production-ready financial analysis toolkit providing ratio analysis, DCF valuation, budget variance analysis, and rolling forecast construction. Designed for financial analysts with 3-6 years experience performing financial modeling, forecasting & budgeting, management reporting, business performance analysis, and investment analysis.
Use when
- The user asks to "run financial ratios", "build a DCF", "analyze budget variance", or "build a forecast"
- A valuation range is needed for an acquisition, fundraise, or board presentation
- Actuals vs budget needs investigation (which variances are material, favorable/unfavorable, department breakdown)
- A rolling 13-week cash flow or driver-based revenue forecast needs construction
- Sensitivity analysis is required to stress-test valuation or forecast assumptions
- The user asks about profitability, liquidity, leverage, efficiency, or valuation metrics with industry context
5-Phase Workflow
Phase 1: Scoping
- Define analysis objectives and stakeholder requirements
- Identify data sources and time periods
- Establish materiality thresholds and accuracy targets
- Select appropriate analytical frameworks
- Validate: materiality threshold is explicit (absolute $ or %), accuracy target is a number, and the decision the analysis supports is named
Phase 2: Data Analysis & Modeling
- Collect and validate financial data (income statement, balance sheet, cash flow)
- Calculate financial ratios across 5 categories (profitability, liquidity, leverage, efficiency, valuation)
- Build DCF models with WACC and terminal value calculations
- Construct budget variance analyses with favorable/unfavorable classification
- Develop driver-based forecasts with scenario modeling
- Validate: input JSON conforms to the expected schema (no missing statements, no mixed periods); WACC inputs sourced within the last quarter; terminal growth rate ≤ long-run GDP growth
Phase 3: Insight Generation
- Interpret ratio trends and benchmark against industry standards
- Identify material variances and root causes
- Assess valuation ranges through sensitivity analysis
- Evaluate forecast scenarios (base/bull/bear) for decision support
- Validate: every material variance has a root-cause hypothesis; DCF sensitivity range is wider than ±15% on WACC and terminal growth
Phase 4: Reporting
- Generate executive summaries with key findings
- Produce detailed variance reports by department and category
- Deliver DCF valuation reports with sensitivity tables
- Present rolling forecasts with trend analysis
- Validate: executive summary leads with the decision-relevant conclusion, not the method; assumptions appendix lists source + last-reviewed date for each
Phase 5: Follow-up
- Track forecast accuracy (target: +/-5% revenue, +/-3% expenses)
- Monitor report delivery timeliness (target: 100% on time)
- Update models with actuals as they become available
- Refine assumptions based on variance analysis
