Step 1: Choose Your Analysis Method

Fundamental Analysis (FA)

Best for long-term investors (3+ years)

  • Examines business health (Revenue, Profits, Debt, YOY Growth, QOQ Growth, Promoter Holding)
  • Uses financial ratios (P/E, ROE, ROCE, Debt-to-Equity)
  • Example: Analyzing HDFC Bank’s quarterly results

Technical Analysis (TA)

Best for traders (1 day-6 months)

  • Studies price charts & patterns
  • Uses indicators (RSI, Moving Averages)
  • Example: Identifying breakout in Reliance stock

2025 Trend: Smart investors now combine FA + TA + AI tools (like Trendlyne).


Step 2: Fundamental Analysis Checklist

A. Financial Statement Analysis

Download annual reports from:

Key Metrics to Check:

Ratio Ideal Value Where to Find
P/E Ratio <25 for large caps Profit & Loss Statement
Debt-to-Equity <1 for most sectors Balance Sheet
ROE (Return on Equity) >15% Cash Flow Statement
Promoter Holding >40% (for stability) Shareholding Pattern

💡 Pro Tip: Compare ratios with industry peers – A Tata Steel P/E of 8 is good if JSW Steel trades at 12.

B. Business Quality Check

Ask these 5 questions:

  1. Does the company have a moat? (Brand, patents, network effects)
  2. Is management trustworthy? (Check for fraud cases via SEBI SCORES)
  3. Is the industry growing? (EV stocks > oil stocks in 2025)
  4. Any regulatory risks? (E.g., FMCG taxes, IT sector visas)
  5. How does COVID-19/geopolitics affect it? (Pharma stocks benefit)

Step 3: Technical Analysis Basics

Must-Know Chart Patterns

Pattern What It Signals Example Stock
Head & Shoulders Trend reversal ITC (2023)
Double Bottom Price bounce Tata Motors (2024)
Cup & Handle Bullish continuation Infosys (2021)

Key Indicators

  • RSI (Relative Strength Index): >70 = Overbought, <30 = Oversold
  • 200-Day MA: Price above = Bullish trend (e.g., Reliance)
  • Volume Spike: Confirms breakout (e.g., Adani Ports)

Step 4: Avoid These 10 Red Flags

🚩 Consistent losses (3+ years of negative profits)
🚩 High promoter pledging (>25% shares pledged)
🚩 Frequent auditor changes
🚩 Negative cash flow (Company burns more cash than it earns)
🚩 Suspicious transactions (Related-party deals)
🚩 Rising debt but falling sales
🚩 SEBI investigations (Check SEBI Orders)
🚩 Low institutional holding (<10% FII/DII stake)
🚩 Extreme valuations (P/E >100 without justification)
🚩 Frequent bonus/splits without profit growth


Step 5: Value the Stock

3 Valuation Methods

  1. DCF (Discounted Cash Flow)
  2. P/E Ratio Comparison
    • If Tata Motors P/E = 12 and industry avg. = 18, it may be undervalued
  3. Dividend Discount Model
    • For high-dividend stocks (ITC, Power Grid)

2025 Tip: AI tools like Trendlyne ValQ automate valuations.
