Analysis Framework

The 5 Core Pillars of Stock Valuation

Fundamental analysis evaluates business operations, balance sheet health, and earnings growth velocity to determine fair equity value.

šŸ¢

Pillar 1: Market Capitalization & Company Tiers

Market Cap

Market Capitalization is the total dollar market value of a company's outstanding shares ($Market\ Cap = Share\ Price \times Total\ Shares$).

Mega-Cap (> $200B) Industry dominators (AAPL, MSFT, NVDA, GOOGL). Highest stability and liquidity.
Large-Cap ($10B - $200B) Established leaders with consistent dividend yields and moderate growth.
Mid/Small-Cap (< $10B) Higher growth potential accompanied by increased price volatility.
šŸ“Š

Pillar 2: Stock Price Valuation Multiples

Full Concepts Guide ā†’

Valuation multiples normalize share price relative to fundamental financial metrics:

  • P/E Ratio (Price-to-Earnings): Measures how much investors pay per dollar of annual profit ($PE = Share\ Price / EPS$). Historical S&P 500 median is ~18ā€“22.
  • PEG Ratio (P/E to Growth): Adjusts P/E for annual earnings growth. A $PEG < 1.0$ suggests undervaluation relative to earnings velocity.
  • P/B (Price-to-Book) & P/S (Price-to-Sales): Evaluates net asset value and revenue volume, critical for tech & financial sectors.

Pillar 3: Balance Sheet Strength & Debt Leverage

A company with high profit margins can still fail if overburdened by excessive debt interest obligations.

Debt-to-Equity (D/E) Ratio Formula D/E = Total Liabilities / Total Shareholders' Equity

Values below 0.5 to 1.0 indicate strong corporate balance sheets capable of withstanding economic recessions and interest rate spikes.

šŸ’µ

Pillar 4: Corporate Profitability & ROE

Profitability ratios measure executive efficiency in converting revenue into shareholder capital:

Net Profit Margin (%) Bottom-line profit after all expenses, taxes, and interest. Margins > 20% indicate competitive moats.
Return on Equity (ROE %) Net Income divided by Shareholder Equity. ROE > 15% demonstrates superior capital allocation.
šŸ›”ļø

Pillar 5: Volatility (Beta) & Portfolio Asset Allocation

Retirement Hub ā†’

Beta ($\beta$) measures an individual stock's volatility relative to the overall market (S&P 500 baseline = 1.0).

  • Beta < 1.0 (Defensive): Less volatile than market index (e.g. Consumer Staples, Utilities).
  • Beta > 1.0 (High Beta): Swings more aggressively than index (e.g. High-growth tech, semiconductors).
