Strategy Overview

Fundamental Value Investing targets companies trading below their intrinsic value. This strategy relies on detailed financial analysis. It seeks a significant margin of safety. Traders hold positions for several months to several years.

Company Selection Criteria

Identify companies with a consistent earnings history. Look for stable revenue growth, minimum 5% annually for the last five years. Require a return on equity (ROE) above 15% for the last three years. Demand a debt-to-equity (D/E) ratio below 0.5. Examine free cash flow (FCF) generation; it must be positive and growing. Avoid highly cyclical industries. Focus on businesses with sustainable competitive advantages. These advantages include strong brands, patent protection, or high switching costs.

Valuation Models

Employ a discounted cash flow (DCF) model for intrinsic value estimation. Project FCF for the next five to ten years. Use a conservative growth rate, typically 2-3% for terminal value. Apply a weighted average cost of capital (WACC) between 8-12%, depending on industry and company risk. Perform sensitivity analysis on growth rates and WACC. Compare the DCF output with other valuation methods. Use a price-to-earnings (P/E) ratio analysis against industry peers. Target companies with a P/E ratio below their historical average and industry average. Consider enterprise value to EBITDA (EV/EBITDA) for capital-intensive businesses. A target EV/EBITDA below 8 is often suitable. Calculate tangible book value per share. Look for a price-to-book (P/B) ratio below 1.5, especially for financial institutions.

Entry Rules

Establish a margin of safety. Do not purchase a stock unless its market price is at least 30% below your calculated intrinsic value. For example, if DCF yields $100 per share, the entry price limit is $70. This buffer protects against valuation errors and unforeseen business headwinds. Initiate a position with 2-5% of total portfolio capital. Avoid overconcentration in a single stock. Spread investments across different sectors to diversify risk. Place limit orders at the target entry price. Do not chase rising prices. Patience is paramount.

Position Sizing and Risk Management

Allocate 2-5% of portfolio capital per position. No single stock should exceed 10% of the portfolio. This limits downside exposure from any individual holding. Set a maximum portfolio exposure to a single sector, typically 20%. Monitor key financial ratios quarterly. If D/E rises above 0.8, re-evaluate. If ROE drops below 10% for two consecutive quarters, review the investment thesis. Maintain a cash reserve, 10-20% of the portfolio. This allows opportunistic buying during market downturns. Regularly review the investment thesis; if the competitive advantage erodes, reconsider the position.

Exit Rules

Exit a position when the market price approaches your calculated intrinsic value. For example, if intrinsic value is $100 and the stock trades at $95, consider exiting. Do not hold beyond fair value. Re-evaluate if the company's fundamentals significantly deteriorate. This includes sustained earnings declines, loss of market share, or increased competition. If the D/E ratio exceeds 1.0, or FCF turns negative for two consecutive years, sell the position. A major change in industry structure or regulatory environment warrants a re-assessment. If a better investment opportunity emerges with a higher margin of safety, consider rotating capital. Do not set arbitrary time-based exits. Exits are fundamentally driven. Sell if the investment thesis breaks, regardless of price action. For instance, if management commits fraud, exit immediately. If the business model becomes obsolete, liquidate the position. Sell a portion of the position if it becomes an outsized percentage of the portfolio, exceeding 15%.
