📝 Equity Research – Investor’s Checklist: The Story of Raj Before Buying a Stock

Raj was an enthusiastic retail investor. One evening, while scrolling through the latest market buzz, he spotted a stock being hyped everywhere. Twitter threads, WhatsApp groups, even his colleagues at work — everyone said it was the “next multibagger.”

Tempted, Raj hovered over the Buy button on his trading app. But then he remembered something his mentor once told him:

“Never invest with excitement. Invest with a checklist.”

That night, Raj pulled out his notebook and started ticking off questions.

📝 Investor Checklist:

✅ Step 1: Business Understanding

Raj asked himself: Do I really understand this company’s business model?

• What does the company sell?
• Who are its customers?
• Does it have a competitive advantage (brand, technology, cost leadership)?

Red Flag: If you can’t explain the business in simple terms, don’t invest.

---

✅ Step 2: Management Quality

Raj flipped through the annual report. He checked the promoters’ track record, corporate governance, and whether auditors had raised concerns.

• Is management honest and shareholder-friendly?
• Any history of fraud or regulatory issues?
• Are promoters pledging their shares heavily?

Red Flag: Frequent auditor resignations, related-party transactions, or excessive pledging.

---

✅ Step 3: Financial Health (Ratios)

Raj knew numbers tell stories too. He checked key ratios:

• Liquidity: Current Ratio > 1, Quick Ratio stable.
• Leverage: Debt-to-Equity not ballooning.
• Profitability: Consistent ROE and margins.
• Cash Flow: Net profit ≈ Operating cash flow.

Red Flag: High profits but weak cash flow → accounting trickery.

---

✅ Step 4: Growth Sustainability

Raj compared revenue and profit growth over 5–10 years. He avoided companies that showed sudden spikes only in the last year.

• Are revenues and earnings growing steadily?
• Or is it a one-hit wonder due to a temporary boom?

Red Flag: Growth dependent on one-time events or subsidies.

---

✅ Step 5: Valuation Check

Finally, Raj compared valuation ratios with peers.

• P/E too high? → Hype.
• P/B very low? → Market distrust.
• EV/EBITDA far above industry? → Overvaluation risk.

Red Flag: Buying “popular” stocks at bubble valuations.

📌 Raj’s Realization

After running through his checklist, Raj realized the hyped stock failed on multiple counts — high debt, weak cash flow, and overpriced. Instead of chasing noise, he shortlisted two other companies that passed most of his tests.

The next morning, while the crowd rushed into the hot stock, Raj calmly bought his chosen picks. Months later, when the hyped stock crashed 40%, Raj’s disciplined approach saved him.

📝 Investor’s Checklist Before Buying Any Stock

1. Understand the business (simple, durable, competitive).
2. Evaluate management (honest, transparent, low pledging).
3. Check financial health (ratios + cash flow).
4. Look for sustainable growth (not one-time boosts).
5. Do valuation sanity check (compare with peers).
6. Cross-verify income vs cash flow (profits must equal cash over time).

📊 How to Check Financial Health

Before buying any stock, smart investors always ask: Is this company financially healthy?

Financial health ratios act like a blood test for a company. They reveal if a business can survive short-term shocks, manage debt, generate profits, and convert those profits into real cash.

Let’s break down the key financial health ratios, the red flags, and where you can find them easily.

---

🔹 1. Liquidity Ratios – Can the company pay its bills?

Current Ratio

Formula:

Current Assets÷Current Liabilities

• Healthy: > 1.5 (enough assets to cover liabilities).)
• Red Flag: < 1 → company may struggle to meet short-term dues.

Quick Ratio (Acid-Test)

Formula:

(Current Assets – Inventory​) / Current Liabilities

• Healthy: > 1.
• Red Flag: Sharp fall → relying on selling inventory to pay debts, risky in downturns.

👉 Source: Balance sheet (current assets, liabilities, inventory).

---

🔹 2. Leverage Ratios – Is debt a ticking time bomb?

Debt-to-Equity (D/E)

Formula:

Total Debt÷Shareholders’ Equity

• Healthy: < 1 for most industries (banks/utilities can be higher).
• Red Flag: Rising D/E → too much borrowing.

Interest Coverage Ratio

Formula: EBIT÷Interest Expense

• Healthy: > 3.
• Red Flag: < 2 → company may default on loans if profits dip.

👉 Source: Income statement (EBIT, interest expense).

---

🔹 3. Profitability Ratios – Is the company really making money?

Gross Margin

Gross Profit÷Revenue

• Red Flag: Declining margin → rising costs or pricing pressure.

Net Profit Margin

Net Income÷Revenue

• Red Flag: Falling despite revenue growth → costs eating profits.

Return on Equity (ROE)

Net Income÷Shareholders’ Equity

• Healthy: 15–20% for good companies.
• Red Flag: Very high ROE driven by debt (not efficiency).

👉 Source: Income statement + balance sheet.

✅ When ROE is Good

• Consistent, sustainable ROE above industry average = strong profitability.
• 10–20% range is considered healthy for most industries.
• High ROE backed by growing revenues and cash flows = competitive advantage.

🚨 ROE Red Flags

1. Very High ROE (>40–50%)
   • Could be due to low equity (not genuine profitability).
   • Often happens if the company has taken on excessive debt (tiny equity base).
   • Example: A debt-heavy company may show inflated ROE but is actually risky.
2. Declining ROE Trend
   • Falling ROE over 3–5 years may signal deteriorating business fundamentals, shrinking margins, or inefficient capital use.
3. ROE Much Higher Than Cash Flow Growth
   • If net income is rising but operating cash flow is weak, profits may not be real.
4. Inconsistent ROE vs. Peers
   • If industry average is ~15% and one company shows 60%, check why. It might be due to accounting adjustments, asset sales, or unsustainable leverage.
5. Negative ROE
   • Occurs when net income is negative → company is loss-making.

⚖️ Bottom Line:
A healthy ROE signals good capital efficiency, but an unusually high or falling ROE should make you dig deeper — especially into debt levels and cash flows.

🔎 What is DuPont Analysis?

Instead of looking at ROE as a single number, DuPont splits it into 3 parts: ROE=NetProfitMargin×AssetTurnover×EquityMultiplierROE = Net Profit Margin \times Asset Turnover \times Equity MultiplierROE=NetProfitMargin×AssetTurnover×EquityMultiplier

Where:

• Net Profit Margin = Net Income ÷ Sales (profitability)
• Asset Turnover = Sales ÷ Assets (efficiency)
• Equity Multiplier = Assets ÷ Equity (financial leverage)

✅ Why It Helps Investors

By decomposing ROE, you can see what’s driving returns:

• Is ROE high because the company is genuinely profitable?
• Or is it high only because of heavy debt?
• Or is it shrinking because sales are weak despite high margins?

🚨 Red Flags DuPont Can Reveal

1. High ROE due to High Leverage (Equity Multiplier)
   • If margins and efficiency are weak, but leverage is high, ROE may look “good” — but the business is riskier.
   • Example: A company taking on lots of debt will have low equity → inflated ROE.
2. Falling Asset Turnover
   • Means the company is using assets inefficiently (poor sales relative to asset size).
   • Could suggest bloated balance sheet, poor management, or slowing demand.
3. Weak Profit Margins but Stable ROE
   • Sometimes, a company boosts ROE by taking on debt or selling assets, hiding the fact that core profitability is weak.
4. Year-to-Year Volatility
   • A stable business shows consistent DuPont components. Big swings may signal accounting tricks, cyclical risk, or one-off gains/losses.

🧩 Investor Use-Case

• If Net Profit Margin drives ROE → business has pricing power, brand strength.
• If Asset Turnover drives ROE → business is efficient in using resources.
• If only Leverage drives ROE → 🚨 red flag → avoid or investigate further.

⚖️ Bottom Line:
DuPont Analysis is like an X-ray of ROE. It helps investors avoid the trap of thinking “high ROE = good business” when in reality, the company may just be piling on debt or underperforming in core operations.

🔹 4. Efficiency Ratios – Is the company using resources well?

Inventory Turnover

COGS÷Average Inventory

• Red Flag: Decline → unsold or obsolete stock.

Receivables Turnover

Net Credit Sales÷Average Accounts Receivable

• Red Flag: Decline → customers not paying.

Asset Turnover

Revenue÷Total Assets

• Red Flag: Falling → underutilized assets.

👉 Source: Income statement + balance sheet (sales, COGS, receivables, assets).

---

🔹 5. Cash Flow Ratios – Profits vs Reality

Operating Cash Flow to Net Income

CFO÷Net Income

• Healthy: Around 1 over long term.
• Red Flag: < 1 → profits not backed by cash.

Free Cash Flow (FCF)

CFO – Capital Expenditure

• Red Flag: Consistently negative while net income is positive → poor earnings quality.

👉 Source: Cash flow statement (CFO, capex).

🧭 Where Can an Investor Find These Ratios?

You don’t need to calculate all ratios manually unless you want to dig deeper.

1. Company Annual Reports → Primary, most authentic source.
   • Balance Sheet, Income Statement, Cash Flow Statement.
   • Notes to accounts explain unusual changes.
2. Stock Market Websites & Data Platforms
   • India: Screener.in, Moneycontrol, NSE/BSE websites.
   • Global: Yahoo Finance, Morningstar, Investing.com.
   • These sites provide pre-calculated ratios + historical trends.
3. Brokerage Reports
   • ICICI Direct, HDFC Securities, Motilal Oswal, etc. publish research reports with ratio analysis.
4. Financial Databases (Pro level)
   • Bloomberg, Capital IQ, Refinitiv, TradingView.

👉 Tip for beginners: Start with free tools like Screener.in (India) or Yahoo Finance (Global) — they display all major ratios with history.

---

✅ Key Takeaway

• Liquidity ratios → survival in the short term.
• Leverage ratios → risk from debt.
• Profitability ratios → efficiency of making profits.
• Efficiency ratios → asset utilization.
• Cash flow ratios → whether profits are real.

Golden Rule: Always look for trends (3–5 years), not just one year. And compare ratios with industry peers to spot hidden red flags.

📌 Investor Action Step

✅ Next time you look at a stock, don’t just glance at the price chart.

• Download the company’s financials (annual reports, Screener.in, Moneycontrol, Yahoo Finance).
• Pull up the checklist.
• Tick off each item honestly.

👉 If the company passes most boxes → consider buying.
👉 If it fails too many → walk away.

Remember: Great investments are found in discipline, not hype.

Investing isn’t about following the noise — it’s about asking the right questions. Raj’s story is every investor’s lesson:

👉 “Buy discipline, not hype.”
