Key Valuation Insights:
Graham Number Formula: √(22.5 × EPS × Book Value per Share). This provides a conservative estimate of fair value based on both earnings power and asset backing.
P/E Ratio Analysis: Graham preferred P/E ratios below 15x for established companies, with adjustments for growth rates and industry characteristics.
Margin of Safety: Central to Graham's philosophy - buy only when market price is significantly below calculated intrinsic value (typically 25-50% discount).
Investment Decision Framework:
- Strong Buy: Market price 40%+ below calculated fair value
- Buy: Market price 20-40% below fair value
- Hold: Market price within ±20% of fair value
- Sell: Market price 20%+ above fair value
- Avoid: Fails multiple Graham criteria or financial strength tests
Understanding Graham's Philosophy:
Mr. Market Concept: Stock prices fluctuate based on emotions rather than fundamentals. Successful investing requires taking advantage of market irrationality while focusing on intrinsic business value.
Circle of Competence: Invest only in businesses you understand thoroughly. Avoid complex financial instruments and trendy sectors outside your expertise.
Defensive vs. Enterprising: Choose an investment approach matching your knowledge, time commitment, and risk tolerance. Defensive investors should focus on diversified, high-quality stocks.
Risk Considerations:
- Industry cycles - Consider sector-specific risks and economic sensitivity
- Management quality - Evaluate leadership track record and capital allocation
- Competitive position - Assess sustainable competitive advantages
- Financial flexibility - Ensure adequate liquidity for economic downturns
- Valuation limitations - Models provide estimates, not precise predictions
