Financial Ratios 

Why Stock Market Basics Matter?

When you’re just starting out in stock investing, financial statements can look intimidating. Pages full of numbers, jargon, and ratios can overwhelm even smart DIY investors.

 But you don’t need to master everything.
Start with 3 simple ratios that give you powerful insights into:

• Profitability (how well the company makes money),
• Risk (how much debt it carries), and
• Valuation (whether you’re overpaying or getting a bargain).

 The 3 Financial Ratios That Matter Most

1. P/E Ratio (Price-to-Earnings) – Valuation Compass

• Formula: Price per Share ÷ Earnings per Share (EPS).
• Meaning: How much are investors willing to pay for ₹1 of earnings?
• Example: A stock trading at ₹500 with EPS of ₹25 has a P/E = 20.
• How to Use:
  • Compared with peers. If sector average P/E = 15 and your stock trades at 30, it’s expensive unless growth justifies it.
  • High P/E isn’t always bad — growth stocks often command premiums.

2. Debt-to-Equity Ratio (D/E) – Risk Radar

• Formula: Total Debt ÷ Shareholder’s Equity.
• Meaning: Shows how much of the company is funded by borrowed money vs owners’ capital.
• Example: A company with ₹500 cr debt and ₹1,000 cr equity = 0.5 D/E → comfortable.
• How to Use:
  • D/E < 1 = healthy for most sectors.
  • Banks and NBFCs are exceptions (leverage is their business model).
  • A rising D/E trend can signal risk, especially in cyclical industries.

3. Return on Equity (RoE) – Profitability Scorecard

• Formula: Net Profit ÷ Shareholder’s Equity × 100.
• Meaning: Measures how efficiently the company generates profit from owners’ funds.
• Example: Company earns ₹200 cr profit on ₹1,000 cr equity → RoE = 20%.
• How to Use:
  • RoE > 15% = generally strong.
  • Compare across years — is it consistent or falling?
  • High RoE with low/no debt = excellent sign.

 ️ Take the Charge: Do This

1. Practice With a Screener
   • Use Moneycontrol, Screener.in, or WealthAlpha.
   • Pull ratios for Infosys, HDFC Bank, ITC, Reliance, and compare.
2. Combine Ratios With Common Sense
   • P/E says it’s expensive — but is growth strong enough to justify it?
   • RoE is high — but is it driven by genuine earnings or excess debt?
3. Remember Ratios Are Just a Start
   • Don’t buy a stock only because “P/E looks low.”
   • Always combine ratio analysis with your understanding of the company’s brand, business model, and industry.

 Decision Guide

• If You Already Invest:
  • Run these 3 checks quarterly on your top holdings.
  • Trim stocks that look expensive and weak on RoE.
• If You’re Just Starting:
  • Start with large, well-known companies.
  • Practice interpreting ratios before buying small/mid-caps.
• If You’re Overwhelmed by Ratios:
  • Stick to these 3 first.
  • Add more advanced ones (PEG, EV/EBITDA, Free Cash Flow) later.

A quick glance tells you ITC looks safer and more profitable vs Reliance’s expensive valuation.

FAQs

Q1: As a beginner, why these 3 ratios?

• P/E helps avoid overpaying.
• D/E helps avoid risky balance sheets.
• RoE shows if management is efficient.

Q2: How do these ratios simplify analysis?

They cut through noise and highlight the three big truths:

• Is it overpriced? (P/E)
• Is it overleveraged? (D/E)
• Is it profitable? (RoE)

Q3: How to apply them practically?

• Pick 3–5 well-known companies.
• Note down their P/E, D/E, RoE from a screener.
• Compare across peers to see who’s stronger, riskier, or overpriced.

Final Takeaway

Don’t drown in financial jargon. Mastering just three ratios — P/E, D/E, RoE — gives you 80% clarity on a company’s valuation, risk, and profitability.
