Value investing has stood the test of time, delivering consistent returns for those who master its principles. As someone who has spent years analyzing markets, I’ve found that the most successful investors adhere to a disciplined, methodical approach. Below, I outline the six core commandments of value investing, blending theory with practical applications.

1. Buy Businesses, Not Stocks
The first rule of value investing is to treat stocks as ownership stakes in real businesses, not just ticker symbols. Warren Buffett famously said, “If you aren’t willing to own a stock for ten years, don’t even think about owning it for ten minutes.”
Key Considerations:
- Economic Moats: A company with a durable competitive advantage (brand loyalty, cost advantages, network effects) will outperform over time.
- Management Quality: Skilled, shareholder-friendly leadership is critical. Look for high insider ownership and capital allocation discipline.
Example:
If Company A has a 20\% return on invested capital (ROIC) while Company B earns only 8\%, Company A is likely the better long-term bet.
2. Margin of Safety: The Bedrock of Value Investing
Benjamin Graham, the father of value investing, emphasized buying securities at a significant discount to their intrinsic value. This “margin of safety” protects against errors in judgment or unforeseen market downturns.
Calculating Intrinsic Value
The discounted cash flow (DCF) model is a common method:
\text{Intrinsic Value} = \sum_{t=1}^{n} \frac{CF_t}{(1 + r)^t} + \frac{TV}{(1 + r)^n}Where:
- CF_t = Cash flow in year t
- r = Discount rate
- TV = Terminal value
Example:
If a stock’s intrinsic value is $100, buying at $70 provides a 30\% margin of safety.
3. Be Contrarian When Necessary
Markets overreact. Fear and greed create mispricings. The best opportunities arise when others panic.
Historical Evidence:
- During the 2008 financial crisis, Wells Fargo (WFC) traded below book value. Investors who bought then saw massive gains.
- In 2020, COVID-19 fears caused strong businesses like Disney (DIS) to drop 40\%+, only to recover sharply.
4. Patience is a Virtue
Value investing is a long-term game. Compounding works best when given time.
FV = PV \times (1 + r)^nWhere:
- FV = Future value
- PV = Present value
- r = Annual return
- n = Number of years
Example:
A $10,000 investment growing at 15\% annually becomes $40,455 in 10 years.
5. Diversify Wisely, Not Excessively
While diversification reduces risk, over-diversification dilutes returns.
| Portfolio Size | Risk Reduction Benefit |
|---|---|
| 5-10 stocks | Significant |
| 20-30 stocks | Marginal |
| 50+ stocks | Minimal |
Concentrate in your best ideas but avoid single-stock risk.
6. Ignore Market Noise
Short-term price movements are distractions. Focus on fundamentals.
Common Pitfalls to Avoid:
- Day-trading based on headlines
- Overreacting to quarterly earnings misses
- Chasing “hot” stocks
Final Thoughts
Value investing isn’t about quick wins—it’s about disciplined, rational decision-making. By following these six commandments, I’ve built a portfolio that withstands market turbulence and grows steadily. The principles of Graham, Buffett, and other greats remain as relevant today as ever.
