Fundamental analysis

Fundamental analysis is the evaluation of a company’s financial statements, business quality, and competitive position to estimate intrinsic value and decide whether a security is under- or overvalued. It answers what to buy or sell; technical analysis and options help with when and how.

Core Concepts (Quick Reference)

The Three Financial Statements

• Income Statement (P&L): Revenue − Expenses = Net income. Key lines: gross profit, operating income (EBIT), net income, EPS. Use for trends in revenue, margins, and earnings quality.

• Balance Sheet: Assets = Liabilities + Equity. Use for liquidity (current ratio, quick ratio), leverage (debt/equity), and book value.

• Cash Flow Statement: Operating (cash from core business), Investing (CapEx, M&A), Financing (debt, dividends, buybacks). Use to check if earnings are backed by cash flow—beware earnings without cash.

Key Ratios

Category	Examples
Profitability	ROE, ROA, gross/operating/net margin
Liquidity	Current ratio, quick ratio
Leverage	Debt/equity, interest coverage
Valuation	P/E, P/B, P/S, EV/EBITDA
Growth	Revenue growth, EPS growth (YoY)

Valuation Approaches

• DCF (Discounted Cash Flow): Estimate future free cash flows; discount to present value. Sensitive to growth and discount rate—use a range of assumptions.

• Multiples: Compare P/E, P/B, EV/EBITDA to peers and history. Adjust for growth and risk.

• Margin of safety: Buy when price is meaningfully below estimated value (e.g. 20–30%+). Graham/Buffett principle.

Qualitative Factors

• Competitive advantage (moat): Brand, scale, network effects, switching costs. Sustained high ROE and margins often reflect a moat.

• Management: Capital allocation, transparency, alignment (insider ownership).

• Industry and risks: Growth vs mature; regulatory, technology, concentration risks.
