Investing: Fundamental Analysis

Fundamental analysis estimates a stock's intrinsic value by studying a company's financial health, business model, and the broader economic environment. If the intrinsic value exceeds the current market price, the stock may be undervalued.

This approach contrasts with technical analysis, which focuses on price patterns and trading volume. Fundamental analysts ask: Is this business worth more than the market currently believes?

• Analysis spans three levels: company, industry, and macroeconomic.
• Analysts use both quantitative (numbers-based) and qualitative (judgment-based) inputs.
• The goal is to find businesses trading below their calculated fair value and hold them long enough for the market to recognize that value.

Three core documents form the backbone of fundamental analysis:

• Income Statement: Shows revenue, operating expenses, and net profit over a period. Look for consistent revenue growth and expanding profit margins.
• Balance Sheet: Snapshots assets, liabilities, and shareholders' equity at a point in time. A healthy current ratio (current assets divided by current liabilities) above 1.5 suggests short-term stability.
• Cash Flow Statement: Tracks cash moving in and out of the business. Free cash flow (operating cash flow minus capital expenditures) shows how much cash is truly available to shareholders.

Statement	Key Line Items	What to Watch
Income Statement	Revenue, gross profit, net income	Margin trends over 3–5 years
Balance Sheet	Total debt, equity, cash	Debt-to-equity ratio below 1.0
Cash Flow	Operating cash flow, capex	Positive and growing free cash flow

Valuation ratios help compare a stock's price to underlying financial performance:

• P/E Ratio (Price-to-Earnings): Stock price divided by earnings per share. A P/E of 15 is often considered fair value for stable companies; growth stocks may trade at 30 or higher.
• P/B Ratio (Price-to-Book): Compares market price to net asset value. A P/B below 1.0 may signal the stock is cheap relative to assets.
• EV/EBITDA: Enterprise value divided by earnings before interest, taxes, depreciation, and amortization. Useful for comparing companies with different capital structures.
• Dividend Yield: Annual dividend divided by share price. A yield above 4% can be attractive but warrants scrutiny for sustainability.
• Return on Equity (ROE): Net income divided by shareholders' equity. An ROE above 15% generally indicates efficient use of capital.
• Debt-to-Equity (D/E): Total debt divided by equity. High D/E ratios above 2.0 may increase financial risk during downturns.

Numbers alone do not tell the full story. Qualitative factors can meaningfully affect a company's long-term value:

• Management Quality: Experienced, shareholder-aligned leadership tends to allocate capital well. Review the CEO's tenure, track record, and ownership stake.
• Business Model: Assess whether revenue is recurring, scalable, and defensible against competition.
• Competitive Advantage (Moat): Companies with strong brands, patents, network effects, or switching costs can maintain pricing power over time.
• Industry Trends: A strong company in a declining industry may still underperform. Evaluate sector tailwinds and the regulatory environment.
• Market Sentiment: Short-term price swings often diverge from fundamentals. Use sentiment as context, not as a primary signal.

Pitfalls to avoid:

• Focusing only on short-term data — use at least 3–5 years of financial history for meaningful trend analysis.
• Ignoring debt levels — a company with strong earnings but unsustainable debt can fail quickly in a downturn.
• Overlooking macroeconomic context — rising interest rates, inflation, and GDP trends all affect valuations.
• Anchoring to purchase price — evaluate the stock on current fundamentals, not the price you originally paid.
