How Ratio Analysis Helps You Avoid Fraudulent Companies in India

About one in ten companies that eventually face fraud allegations show clear warning signs in their published financial ratios at least two years before the fraud breaks. That is the conclusion from investing/forensic-accounting-avoid-traps">forensic accounting research across emerging markets including India. Financial ratios for fcf-yield-vs-pe-ratio-myth">valuation-methods/value-ipo-before-investing">stock analysis in India are not just for valuation — used systematically, they form an early warning system that catches red flags long before headlines do.

Here is how to apply eps-vs-reported-eps">ratio analysis specifically to spot fraudulent or aggressive accounting, with the exact ratios, thresholds and combinations that matter.

Why ratios reveal fraud that auditors miss

Auditors check transactions and procedures. They rarely have time to dig into the cumulative pattern across years. Ratios reveal patterns. Fraud usually distorts only some line items, but those distortions create unnatural relationships between numbers — and ratios make those relationships visible.

For example, a company can inflate revenue without changing cash flow, but the ratio of cash flow from operations to net profit drops sharply. Or a company can disguise loans as customer advances, but the working-capital ratio shifts in a way that does not match the business cycle.

The first three ratios to compute on any Indian stock

Before going deeper, run these three quick checks for the most recent five years:

• Cash Flow from Operations to Net Profit — should be close to or above 1.0 in a healthy company. A persistent ratio below 0.6 suggests profits not backed by cash
• Receivables Days — accounts receivable divided by daily revenue. Steady increase across years signals revenue without collection
• Other Current Assets to Total Assets — a rising share of "other" assets often hides loans, advances or off-book exposures

If two or more of these flag, dig deeper before considering the stock.

Sub-section: classic fraud-detection ratios

1. The Beneish M-Score

Developed by Professor Messod Beneish, this combines eight ratios into a single score. Companies with an M-Score above -1.78 are statistically more likely to be earnings manipulators. The eight components include:

• Days Sales in Receivables Index
• mcx-and-commodity-trading/trading-mcx-base-metals-limited-capital-risk-tips">margin-crucial-evaluating-growth-stocks">Gross Margin Index
• Asset Quality Index
• Sales Growth Index
• Depreciation Index
• SGA Expense Index
• Leverage Index
• Total Accruals to Total Assets

You can compute the M-Score from any company's filings. A persistent score above -1.78 across multiple years is a strong red flag.

2. The Altman Z-Score

Originally built to predict bankruptcy, the Altman Z-Score is also useful as a fraud filter. Companies under financial stress are more likely to manipulate accounts. A Z-Score below 1.8 means high distress risk; between 1.8 and 3.0 is the grey zone; above 3.0 is safer.

3. Operating Cash Flow to Total Liabilities

If operating cash flow is consistently below 10 percent of total liabilities, the company is funding operations through debt or equity rather than the underlying business. That is not always fraud, but it pairs badly with other red flags.

Sub-section: ratio combinations that signal fraud

A single ratio at an extreme is rarely conclusive. Combinations are more powerful:

• Rising revenue + falling operating cash flow + rising receivables = revenue inflation pattern
• Rising profit margin + rising depreciation period + rising other current assets = expense capitalisation pattern
• Rising debt + falling interest cost + auditor change = debt mis-classification pattern
• Stable margins + rising esg-and-sustainable-investing/best-esg-scores-indian-companies">governance/promoter-losing-control-company-signs">related-party transactions + falling sebi-shareholding-pattern-disclosures">promoter holding = promoter exit pattern

Each pattern has been observed in Indian corporate frauds over the past two decades. Treat them as standardised checks.

Sub-section: industry-specific adjustments

Ratios are not universal. They behave differently by industry:

• NBFCs and banks need different ratios — savings-schemes/scss-maximum-investment-limit">investments">Net Interest Margin, Gross NPA percent, Capital Adequacy
• Software services companies generate high cash conversion; a fall in cash flow to profit is more meaningful than for capital-heavy industries
• Real estate and construction lag in revenue recognition; receivables days can naturally be high without indicating fraud
• Pharma companies invest heavily in R&D, so SGA-to-sales ratios are higher and not a flag

Always benchmark against the industry, not the broader market.

Real-world case patterns to keep in mind

Several Indian listed companies, on closer inspection of their five-year ratio trends, showed clear fraud patterns:

• Steady rise in receivables days while revenue growth slowed
• Operating cash flow consistently far below reported net profit
• Auditor etfs-and-index-funds/etf-brokerage-stt-calculation">turnover within a couple of years of suspect financials
• Promoter holding decreasing while reported earnings rose
• Sharp jumps in "other current assets" with no clear disclosure

Investors who ran simple ratio analysis would have seen the warning at least 6 to 8 quarters before the public disclosures.

How to build a personal fraud-screen workflow

Create a small dashboard for any company you track:

1. Pull five years of standalone financials from official filings
2. Compute the three primary ratios — CFO to Net Profit, Receivables Days, Other Current Assets to Total Assets
3. Compute Beneish M-Score and Altman Z-Score
4. Compare each metric against industry medians
5. Flag any ratio outside the normal range, then look for combinations

If the dashboard shows multiple flags, demand answers from the company's investor relations or skip the stock.

Where to source clean data

Standalone and consolidated filings are available on the exchanges. For company-level filings and disclosures, the official portals at SEBI and the Ministry of Corporate Affairs are authoritative.

Frequently Asked Questions

Can ratio analysis catch every fraud?

No. Sophisticated fraud may be hidden through related-party structures or off-balance-sheet entities. But the majority of historical Indian frauds left ratio footprints visible to attentive investors.

Which is the single most useful ratio for fraud detection?

Operating Cash Flow to Net Profit. A persistent gap between earnings and cash is the hardest pattern to fake.

How frequently should I recompute these ratios?

Once per quarter, after the company files its results. Annual review is the absolute minimum for a long-term investor.
