How to Build an Investment Checklist: Never Forget What Matters

Pilots use checklists before every flight — even after thousands of hours of experience. Surgeons use checklists before every operation. Investors should too. A simple checklist prevents you from making emotional decisions and forgetting critical questions.

Why You Need a Checklist

When you are excited about a stock, your brain overlooks red flags. When you are scared, you ignore opportunities. A checklist forces you to evaluate every investment systematically, regardless of how you feel about it in the moment.

The best checklists are short enough to use every time but thorough enough to catch mistakes. Aim for 8-12 questions that cover the most important aspects of any investment.

The Quality Checklist

1. Does the company have a durable competitive advantage? Identify the moat source — brand, switching costs, network effects, cost advantage, or regulatory protection. If you cannot name the moat clearly, the company probably does not have one.

2. Has ROIC been above 15% consistently for 5+ years? ROIC is the single best indicator of business quality. One good year is not enough. Look for consistently high returns through different economic conditions.

3. Are margins stable or improving? Check gross margin and EBIT margin trends over 5 years. Expanding margins suggest pricing power. Volatile or shrinking margins suggest competitive pressure.

4. Does the company generate real free cash flow? Compare free cash flow to reported earnings. A company that consistently reports earnings but burns cash is a red flag.

The Valuation & Risk Checklist

5. Is the FCF/EV yield above 4%? For a quality business, an FCF yield below 2% usually means the market is pricing in perfection. Above 5% is an attractive entry point.

6. Is the balance sheet strong? Net debt to EBITDA below 2x is generally safe. Above 4x is dangerous for most businesses. Financial companies are different — check CET1 ratios instead.

7. Does management think like owners? Check insider ownership. If executives own meaningful stakes (above 5% is a good start), they are more likely to make decisions that benefit long-term shareholders.

8. What could go wrong? List three specific things that could permanently impair the business. If you cannot think of any, you are not thinking hard enough. Every investment has risks — the question is whether you understand them.

Using Your Checklist

Print your checklist. Keep it next to your computer. Run through it before every investment. If you cannot answer all 8 questions with confidence, do not invest until you can. The checklist will not guarantee success, but it will prevent the most common mistakes — and that is more than half the battle.
