What is Fundamental Analysis?

Fundamental analysis is the cornerstone of intelligent investing - evaluating a company’s intrinsic value by examining its financial health, business model, competitive position, and growth prospects to make informed investment decisions.

​
Why Fundamental Analysis Matters

Fundamental analysis helps you answer the most important investment question: “Is this company’s stock price justified by its underlying business value?” This approach has made legendary investors like Warren Buffett, Peter Lynch, and Benjamin Graham incredibly wealthy.

​
The Investment Philosophy

Value vs. Price: Price is what you pay, value is what you get. Fundamental analysis helps you identify when a stock’s price is significantly different from its intrinsic value. Long-term Perspective: While stock prices fluctuate wildly in the short term, they tend to reflect business fundamentals over longer periods. Competitive Advantage: The best investments are companies with sustainable competitive advantages (moats) that protect their profits from competition.

​
What Fundamental Analysis Reveals

  • Financial Health: Is the company profitable and growing?
  • Business Quality: Does it have competitive advantages?
  • Management Quality: Are executives making smart decisions?
  • Valuation: Is the stock cheap, fair, or expensive?
  • Growth Prospects: What’s the potential for future expansion?

​
The Three Essential Financial Statements

Understanding financial statements is like learning to read - it’s essential for investment success. Every public company publishes these quarterly and annually.

​
Income Statement

Shows profitability over a period (quarter/year)

Revenue$100M
- COGS$60M
Gross Profit$40M
- Operating Exp$25M
Net Income$15M

​
Balance Sheet

Snapshot of assets, liabilities, and equity

Cash$50M
Other Assets$150M
Total Assets$200M
Debt$80M
Equity$120M

​
Cash Flow Statement

Tracks actual cash movements

Operating CF$20M
Investing CF($10M)
Financing CF($5M)
Net Cash Flow$5M

​
Understanding the Income Statement

The income statement tells the story of a company’s profitability over a specific period. Think of it as a report card for how well management converted sales into profits. Revenue (Top Line): Total money coming in from sales
  • Quality Check: Is revenue growing consistently? Is growth from new customers or higher prices?
  • Red Flags: Declining revenue, heavy dependence on one customer, one-time revenue boosts
Cost of Goods Sold (COGS): Direct costs to produce products/services
  • Analysis: Lower COGS as % of revenue suggests improving efficiency or pricing power
  • Benchmark: Compare COGS margins to industry competitors
Gross Profit = Revenue - COGS
  • Interpretation: Higher gross margins indicate pricing power and competitive advantages
  • Example: Apple’s ~38% gross margins vs. Dell’s ~23% shows Apple’s premium pricing ability
Operating Expenses: Costs to run the business (R&D, marketing, administration)
  • Growth Phase: High R&D spending can indicate future growth investment
  • Mature Phase: Operating leverage should improve margins as revenue grows
Net Income (Bottom Line): Final profit after all expenses and taxes
  • Growth Pattern: Look for consistent growth over multiple years
  • Quality: Prefer companies that grow earnings faster than revenue (improving margins)
  • Income Statement
  • Balance Sheet
  • Cash Flow Statement
Shows company’s revenues, expenses, and profits over a period (quarterly/annually).
Key Components:
Revenue (Top Line)
- Cost of Goods Sold (COGS)
= Gross Profit
- Operating Expenses
= Operating Income (EBIT)
- Interest & Taxes
= Net Income (Bottom Line)

Revenue Growth

Look for consistent, sustainable revenue growth over multiple quarters

Profit Margins

Compare gross, operating, and net margins to industry averages

​
Key Financial Ratios

​
Profitability Ratios

Gross Margin

Gross Margin = (Revenue - COGS) / Revenue × 100%
What it shows: Efficiency of core operationsGood Range: Varies by industry
  • Software: 70-90%
  • Retail: 20-40%
  • Manufacturing: 30-50%

Return on Equity (ROE)

ROE = Net Income / Shareholders' Equity × 100%
What it shows: How effectively management uses equityBenchmark:
  • Excellent: > 20%
  • Good: 15-20%
  • Average: 10-15%

Return on Assets (ROA)

ROA = Net Income / Total Assets × 100%
What it shows: How efficiently company uses assetsGenerally: Higher is better, compare within industry

Net Profit Margin

Net Margin = Net Income / Revenue × 100%
What it shows: Overall profitability after all expensesIndustry Comparison: Essential for meaningful analysis

​
Valuation Ratios

1

Price-to-Earnings (P/E)

Formula: Stock Price ÷ Earnings Per ShareInterpretation:
  • Low P/E: Potentially undervalued or slow growth
  • High P/E: Growth expectations or overvaluation
  • Compare to industry average and historical P/E
2

Price-to-Book (P/B)

Formula: Stock Price ÷ Book Value Per ShareUse Cases:
  • Value investing screening
  • Asset-heavy industries
  • P/B < 1 may indicate undervaluation
3

Price-to-Sales (P/S)

Formula: Market Cap ÷ Annual RevenueBenefits:
  • Useful for unprofitable companies
  • Less manipulable than earnings
  • Good for growth companies

​
Competitive Analysis

Porter's Five Forces

Framework for analyzing competitive dynamics and industry attractiveness.

Threat of New Entrants

High Barriers = Good
  • High capital requirements
  • Strong brand loyalty
  • Regulatory barriers
  • Network effects

Bargaining Power of Suppliers

Lower Power = Better
  • Multiple supplier options
  • Standardized inputs
  • Forward integration ability

Bargaining Power of Buyers

Lower Power = Better
  • Fragmented customer base
  • High switching costs
  • Unique product offering

Threat of Substitutes

Lower Threat = Better
  • High switching costs
  • Superior performance
  • Strong brand preference

​
Economic Moats

An economic moat is a sustainable competitive advantage that protects a company’s profits from competitors.
  • Network Effects
  • Brand Power
  • Cost Advantages
  • Switching Costs
Definition: Product becomes more valuable as more people use itExamples:
  • Social media platforms (Facebook, LinkedIn)
  • Payment networks (Visa, Mastercard)
  • Marketplaces (Amazon, eBay)
Strength: Very difficult to replicate once established

​
Valuation Methods

​
Discounted Cash Flow (DCF)

# Simplified DCF Model
def dcf_valuation(free_cash_flows, terminal_growth, discount_rate):
    """
    Calculate intrinsic value using DCF method
    """
    present_values = []

    # Discount projected cash flows
    for year, fcf in enumerate(free_cash_flows, 1):
        pv = fcf / (1 + discount_rate) ** year
        present_values.append(pv)

    # Terminal value
    terminal_fcf = free_cash_flows[-1] * (1 + terminal_growth)
    terminal_value = terminal_fcf / (discount_rate - terminal_growth)
    terminal_pv = terminal_value / (1 + discount_rate) ** len(free_cash_flows)

    # Total enterprise value
    enterprise_value = sum(present_values) + terminal_pv

    return enterprise_value

# Example calculation
projected_fcf = [100, 110, 121, 133, 146]  # 5-year projections
terminal_growth = 0.03  # 3% perpetual growth
discount_rate = 0.10    # 10% WACC

intrinsic_value = dcf_valuation(projected_fcf, terminal_growth, discount_rate)

​
Comparable Company Analysis

Process:
  1. Identify comparable companies (same industry, size, business model)
  2. Calculate key multiples (P/E, EV/EBITDA, P/S)
  3. Apply median/average multiples to target company
  4. Derive implied valuation range
Example:
Comparable P/E ratios: 15x, 18x, 22x, 16x, 20x
Median P/E: 18x
Target EPS: $5.00
Implied Value: 18 × $5.00 = $90 per share

​

These warning signs could indicate potential problems with a company’s financial health or management integrity.

Accounting Red Flags

  • Frequent auditor changes
  • Aggressive revenue recognition
  • Growing gap between earnings and cash flow
  • Off-balance sheet liabilities

Business Red Flags

  • Declining market share
  • Heavy dependence on few customers
  • Excessive management turnover
  • Insider selling at high levels

Financial Red Flags

  • Deteriorating margins

​
Putting It All Together

1

Industry Analysis

Understand the industry dynamics, growth prospects, and key success factors
2

Company Quality

Assess business model, competitive advantages, and management quality
3

Financial Health

Analyze financial statements and key ratios for trends and red flags
4

Valuation

Use multiple methods (DCF, comparables) to estimate intrinsic value
5

Investment Decision

Compare intrinsic value to current price, considering margin of safety
Margin of Safety: Only invest when the stock trades significantly below your calculated intrinsic value. This protects against estimation errors and unforeseen events.
