Quality Scoring Framework
Piotroski F-Score (0–9)
The Piotroski F-Score measures financial strength and operating improvement across 9 binary criteria. Each criterion scores 1 (pass) or 0 (fail). Score of 8–9 is strong; 0–2 is weak.
Profitability Signals (4 criteria):
| # | Criterion | Formula | Pass Condition | Score |
|---|
| 1 | ROA > 0 | Net Income / Total Assets | Positive ROA in current year | 0 or 1 |
| 2 | Operating Cash Flow > 0 | CFO from cash flow statement | Positive CFO | 0 or 1 |
| 3 | Change in ROA | ROA(t) − ROA(t-1) | ROA improved year-over-year | 0 or 1 |
| 4 | Accruals (quality) | CFO / Total Assets > ROA | Cash earnings exceed reported earnings | 0 or 1 |
Leverage, Liquidity & Source of Funds (3 criteria):
| # | Criterion | Formula | Pass Condition | Score |
|---|
| 5 | Change in Leverage | Long-term Debt / Avg Assets | Leverage decreased YoY | 0 or 1 |
| 6 | Change in Liquidity | Current Ratio(t) vs (t-1) | Current ratio improved YoY | 0 or 1 |
| 7 | No New Shares Issued | Diluted shares outstanding | No new equity issuance in past year | 0 or 1 |
Operating Efficiency (2 criteria):
| # | Criterion | Formula | Pass Condition | Score |
|---|
| 8 | Change in Gross Margin | Gross Margin(t) vs (t-1) | Gross margin expanded YoY | 0 or 1 |
| 9 | Change in Asset Turnover | Revenue / Total Assets | Asset turnover improved YoY | 0 or 1 |
F-Score Interpretation:
- 8–9: Strong financial position — high-quality candidate
- 5–7: Average quality — neutral
- 0–2: Weak financial position — high risk of deterioration
Earnings Quality Score
- Accruals Ratio: (Net Income − CFO) / Average Total Assets. Low or negative accruals indicate high earnings quality (cash-backed profits).
- Cash Conversion Rate: CFO / Net Income. Ratio consistently above 1.0x is positive. Below 0.7x signals potential earnings inflation.
- Non-Recurring Items: Identify and strip out restructuring charges, asset write-downs, gains on asset sales, and one-time tax benefits from normalized earnings.
- Revenue Recognition Risk: Assess channel stuffing, bill-and-hold arrangements, and aggressive deferred revenue recognition.
ROIC / WACC Analysis
ROIC Calculation
ROIC = NOPAT / Invested Capital
- NOPAT (Net Operating Profit After Tax) = EBIT × (1 − effective tax rate)
- Invested Capital = Total Equity + Total Debt − Cash and Cash Equivalents
- Alternatively: Invested Capital = Net PP&E + Net Working Capital + Goodwill + Other Long-term Operating Assets
| Component | Value |
|---|
| EBIT | |
| Effective Tax Rate | |
| NOPAT | |
| Total Equity | |
| Total Debt | |
| Less: Cash | |
| Invested Capital | |
| ROIC | |
WACC Calculation
WACC = (E/V) × Re + (D/V) × Rd × (1 − T)
- Cost of Equity (Re) via CAPM: Re = Rf + β × (Rm − Rf)
- Rf: Risk-free rate (current 10-year Treasury yield)
- β: Stock beta (5-year monthly vs. S&P 500)
- (Rm − Rf): Equity risk premium (historical ~5–6%)
- Cost of Debt (Rd): Weighted average interest rate on outstanding debt
- Capital Structure Weights: E/V = market cap / (market cap + total debt), D/V = total debt / (market cap + total debt)
- Tax Shield: Multiply Rd by (1 − marginal tax rate) to reflect interest deductibility
| Component | Value |
|---|
| Risk-Free Rate (Rf) | |
| Beta (β) | |
| Equity Risk Premium | |
| Cost of Equity (Re) | |
| Pre-Tax Cost of Debt | |
| Tax Rate | |
| After-Tax Cost of Debt | |
| Equity Weight (E/V) | |
| Debt Weight (D/V) | |
| WACC | |
Economic Value Added (EVA)
EVA = (ROIC − WACC) × Invested Capital
- ROIC > WACC: Company is creating economic value — every dollar invested earns more than its cost. Strong positive signal.
- ROIC = WACC: Company is breaking even economically — no value creation or destruction.
- ROIC < WACC: Company is destroying shareholder value — capital is deployed below its opportunity cost. Significant warning sign.
ROIC vs. WACC spread trend (expanding = improving value creation, compressing = deteriorating):
| Year | ROIC | WACC | Spread | EVA |
|---|
| Current | | | | |
| -1 Year | | | | |
| -2 Year | | | | |
| -3 Year | | | | |
DCF Framework
Step-by-Step DCF Methodology
Step 1 — Project Free Cash Flow (Years 1–10)
- Start with current year base FCF = Operating Cash Flow − Maintenance Capex
- Apply revenue growth rate assumptions (differentiate Phase 1: high growth, Phase 2: fade to stable)
- Apply operating margin assumptions (expanding/stable/compressing)
- Deduct taxes and changes in net working capital
- FCF = NOPAT + D&A − Change in Working Capital − Capex
Step 2 — Terminal Value Calculation
- Gordon Growth Model: TV = FCF(Year 10) × (1 + g) / (WACC − g)
- Exit Multiple Method: TV = EBITDA(Year 10) × Terminal EV/EBITDA multiple
- Terminal growth rate (g): typically 2–3% (in line with long-run nominal GDP growth)
- Cross-check both methods for reasonableness
Step 3 — Discount to Present Value
- Discount each year's FCF: PV(FCFt) = FCFt / (1 + WACC)^t
- Discount terminal value: PV(TV) = TV / (1 + WACC)^10
- Enterprise Value = Sum of all discounted FCFs + PV(Terminal Value)
- Equity Value = Enterprise Value − Net Debt
- Intrinsic Value Per Share = Equity Value / Diluted Shares Outstanding
Key Assumptions
| Assumption | Base Case | Bull Case | Bear Case |
|---|
| Revenue Growth Yr 1–5 | | | |
| Revenue Growth Yr 6–10 | | | |
| Operating Margin | | | |
| Tax Rate | | | |
| Capex (% Revenue) | | | |
| WACC | | | |
| Terminal Growth Rate | | | |
| Terminal EV/EBITDA | | | |
Sensitivity Table
Intrinsic value per share at various WACC and terminal growth rate combinations:
| WACC \ Terminal Growth | 1.5% | 2.0% | 2.5% | 3.0% | 3.5% |
|---|
| 7% | | | | | |
| 8% | | | | | |
| 9% | | | | | |
| 10% | | | | | |
| 11% | | | | | |
Margin of Safety Assessment
- Intrinsic Value (Base Case):
- Current Market Price:
- Premium / (Discount) to Intrinsic Value:
- Margin of Safety: (Intrinsic Value − Market Price) / Intrinsic Value × 100%
-
30% discount: Significant margin of safety — compelling value
- 10–30% discount: Moderate margin of safety — attractive
- 0–10% discount: Limited margin of safety — fairly valued
- Trading at premium: No margin of safety — risk of capital loss if assumptions miss
Management Quality Assessment
Capital Allocation Track Record
- ROIC Trend: Is management generating returns above cost of capital consistently? Review 5-year ROIC history.
- Acquisition History: Evaluate past M&A for value creation. Did acquired assets earn above WACC? Were goodwill impairments taken post-acquisition?
- Buyback Timing: Did management repurchase shares below intrinsic value? Assess buyback price vs. subsequent performance.
- Dividend Policy: Sustainable payout ratio? Dividend growth track record. Balance between dividends, buybacks, and reinvestment.
- Capex Discipline: Differentiate growth capex vs. maintenance capex. Asset-light vs. capital-intensive business assessment.
Guidance Accuracy History (Last 8 Quarters)
| Quarter | EPS Guidance | EPS Actual | Beat/Miss | Revenue Guidance | Revenue Actual | Beat/Miss |
|---|
| Q1 | | | | | | |
| Q2 | | | | | | |
| Q3 | | | | | | |
| Q4 | | | | | | |
| Q5 | | | | | | |
| Q6 | | | | | | |
| Q7 | | | | | | |
| Q8 | | | | | | |
| Rate | | | X/8 | | | X/8 |
- Beat rate above 75% (6+/8) is strong. Below 50% suggests overpromising or deteriorating visibility.
- Assess guidance conservatism (sandbagging tendency) vs. optimism bias.
Insider Ownership Alignment
- CEO ownership (% of shares outstanding): > 3% meaningful, > 10% highly aligned
- Board ownership: Independent directors with meaningful personal stakes indicate alignment
- Recent insider transactions: Open-market buys are strongly positive; sells can be routine diversification
- Insider buy/sell ratio over past 12 months
- 10b5-1 plan activity: Scheduled plan sales are less informative than discretionary transactions
Compensation Structure
- Pay-for-performance alignment: Are bonuses and equity vesting tied to ROIC, FCF, and total shareholder return (TSR)?
- Long-term equity grants: Stock option or RSU vesting periods (3+ years preferred)
- CEO pay ratio: Context for compensation relative to company size and peers
- Say-on-pay vote: Shareholder approval percentage in most recent proxy vote
- Excessive compensation red flags: Guaranteed bonuses, repriced options, change-of-control severance packages
