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.

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

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

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

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

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

Tools

1. Ratio Calculator (scripts/ratio_calculator.py)

Calculate and interpret financial ratios from financial statement data.

Ratio Categories:

• Profitability: ROE, ROA, Gross Margin, Operating Margin, Net Margin

• Liquidity: Current Ratio, Quick Ratio, Cash Ratio

• Leverage: Debt-to-Equity, Interest Coverage, DSCR

• Efficiency: Asset Turnover, Inventory Turnover, Receivables Turnover, DSO

• Valuation: P/E, P/B, P/S, EV/EBITDA, PEG Ratio

2. DCF Valuation (scripts/dcf_valuation.py)

Discounted Cash Flow enterprise and equity valuation with sensitivity analysis.

Features:

• WACC calculation via CAPM

• Revenue and free cash flow projections (5-year default)

• Terminal value via perpetuity growth and exit multiple methods

• Enterprise value and equity value derivation

• Two-way sensitivity analysis (discount rate vs growth rate)

  python scripts/dcf_valuation.py valuation_data.json python scripts/dcf_valuation.py valuation_data.json --format json python scripts/dcf_valuation.py valuation_data.json --projection-years 7

3. Budget Variance Analyzer (scripts/budget_variance_analyzer.py)

Analyze actual vs budget vs prior year performance with materiality filtering.

Features:

• Dollar and percentage variance calculation

• Materiality threshold filtering (default: 10% or $50K)

• Favorable/unfavorable classification with revenue/expense logic

• Department and category breakdown

• Executive summary generation

  python scripts/budget_variance_analyzer.py budget_data.json python scripts/budget_variance_analyzer.py budget_data.json --format json python scripts/budget_variance_analyzer.py budget_data.json --threshold-pct 5 --threshold-amt 25000

4. Forecast Builder (scripts/forecast_builder.py)

Driver-based revenue forecasting with rolling cash flow projection and scenario modeling.

Features:

• Driver-based revenue forecast model

• 13-week rolling cash flow projection

• Scenario modeling (base/bull/bear cases)

• Trend analysis using simple linear regression (standard library)

  python scripts/forecast_builder.py forecast_data.json python scripts/forecast_builder.py forecast_data.json --format json python scripts/forecast_builder.py forecast_data.json --scenarios base,bull,bear
