Edward Altman developed the Z-Score formula in 1968 to predict the probability of a company going bankrupt within two years. Over five decades later, it remains one of the most widely used financial distress indicators in the world — used by credit analysts, auditors, value investors, and even SEBI-registered portfolio managers screening Indian equities.
We ran the Altman Z-Score across 2,700+ NSE-listed companies using the latest quarterly financial data from Capital Advantage's database. Here's what we found.
What is the Altman Z-Score?
The Z-Score is a weighted combination of five financial ratios that together predict financial distress:
- Z = 1.2A + 1.4B + 3.3C + 0.6D + 1.0E
Where:
- A = Working Capital / Total Assets — Measures short-term liquidity. Negative working capital is a red flag.
- B = Retained Earnings / Total Assets — Measures cumulative profitability. Young companies score low here.
- C = EBIT / Total Assets — Measures operating efficiency. The highest-weighted component (3.3x).
- D = Market Cap / Total Liabilities — Market's view of solvency. Uses live market cap, not book equity.
- E = Revenue / Total Assets — Measures asset turnover. How efficiently assets generate sales.
Interpreting the Score
- Z > 2.99 — Safe Zone: Low probability of financial distress. Most blue-chip Indian companies fall here.
- 1.81 < Z < 2.99 — Grey Zone: Caution. The company has some distress characteristics. Needs deeper analysis.
- Z < 1.81 — Distress Zone: Elevated bankruptcy risk. Altman's original study showed 95% accuracy in predicting failures within this zone over a 2-year horizon.
What Our Screening Revealed
Across 2,700+ NSE-listed companies with sufficient financial data, the distribution breaks down approximately as:
- ~55% in the Safe Zone (Z > 2.99) — The majority of actively traded Indian stocks are financially healthy
- ~20% in the Grey Zone (1.81–2.99) — Require case-by-case analysis
- ~25% in the Distress Zone (Z < 1.81) — Including many micro-caps, turnaround stories, and capital-intensive businesses
Sectors Concentrated in the Distress Zone
- Real Estate & Construction — High leverage, lumpy revenue recognition, and asset-heavy balance sheets naturally produce low Z-Scores. Many Indian real estate firms carry significant debt.
- Metals & Mining — Cyclical revenue, high fixed assets, and commodity price sensitivity.
- Telecom & Utilities — Capital-intensive with thin margins. The Vodafone Idea story is a textbook distress-zone example.
- Micro-cap industrials — Low retained earnings, limited track record, and small market caps deflate the D component.
Sectors Concentrated in the Safe Zone
- IT Services — Asset-light, high retained earnings, strong margins. TCS, Infosys, HCL Tech all score well above 3.0.
- FMCG — Steady revenue, low leverage, high asset turnover. HUL, Nestle, Dabur are consistently safe.
- Pharma — Strong profitability metrics and moderate leverage keep most pharma stocks in the safe zone.
Important Caveats for Indian Markets
Banks and NBFCs: Use the Z'-Score
The original Altman Z-Score was designed for manufacturing companies. For financial firms, “Working Capital” and “Revenue / Total Assets” don't have the same meaning. Altman later developed the Z'-Score (Z-prime) for non-manufacturing companies, which Capital Advantage computes automatically when the company is classified as financial services.
Young Companies Score Low — That's Expected
The B component (Retained Earnings / Total Assets) penalizes recently listed companies. A company that IPO'd 2 years ago will naturally have lower retained earnings than a company listed for 20 years. This doesn't mean it's distressed — it means the Z-Score should be used alongside other metrics, not in isolation.
Market Cap Swings Affect the Score
The D component uses live market capitalization. During a broad market selloff, even fundamentally healthy companies can see their Z-Score drop as their market cap declines. This is a feature, not a bug — the market is pricing in higher risk — but it means Z-Scores should be evaluated over time, not as a single snapshot.
How to Use Z-Score in Your Investment Process
- As a negative screen — Avoid stocks in the distress zone unless you're specifically doing turnaround investing. This alone eliminates many value traps.
- Combined with Piotroski F-Score — Use Z-Score for solvency risk and F-Score for earnings quality. A stock with Z > 3.0 AND F-Score > 7 is both solvent and operationally improving.
- For debt-heavy sectors — In real estate, infra, and metals, Z-Score is more informative than PE ratio. A low PE might look like value, but a low Z-Score tells you it might be a trap.
- Tracking over time — A deteriorating Z-Score (moving from safe to grey) is an early warning signal, often months before the stock price reacts.
