Building Your Stock Screening Checklist

Part 1: The Purpose of a Stock Screening Checklist

Before we build the checklist, let's understand its purpose. A stock screening checklist is a set of predefined criteria used to filter stocks. Given your background in IT, you can think of this as running a query against a large database of companies to return only the results that match your specific parameters. It's a systematic way to enforce discipline and save an immense amount of time.

Let's hear from an experienced investor on how he starts his research process.

As you saw, the goal isn't to make a final decision but to efficiently discard companies that clearly don't meet your minimum standards. This allows you to focus your valuable research time on better-than-average opportunities.

Part 2: The Quantitative Checklist: Assessing Financial Health

The quantitative part of your checklist uses the financial ratios and metrics we've covered in previous modules. It answers objective questions about a company's financial performance and stability.

Here are the key categories to include:

1. Valuation: Is the price reasonable?
As investor Howard Marks says, "There's no such thing as a good or bad idea regardless of price." The best company can be a terrible investment if you overpay for it.

• Key Metrics:
  • Price-to-Earnings (P/E) Ratio: Should be reasonable compared to the industry average.
  • Price-to-Book (P/B) Ratio: Useful for asset-heavy industries.

2. Profitability: Is it an efficient business?
A profitable company is one that effectively turns revenue into actual profit.

• Key Metrics:
  • Return on Equity (ROE): Measures how much profit the company generates with shareholders' money. A consistent ROE above 15% is often considered a sign of a quality business.
  • Net Profit Margin: Indicates what percentage of revenue is left after all expenses are paid.

3. Financial Strength: Is the company solvent?
High debt can be a significant risk, especially during economic downturns. A strong balance sheet provides a safety cushion.

• Key Metrics:
  • Debt-to-Equity (D/E) Ratio: Compares total debt to shareholder equity. A ratio below 1.0 is generally preferred, though this can vary by industry.
  • Current Ratio: Measures the company's ability to pay its short-term bills. A ratio above 1.5 is a healthy sign.
  • Operating Cash Flow: Should be consistently positive. Profit on paper is good, but cash is what keeps a business running.

4. Growth: Is the company expanding?
You want to invest in businesses with a future.

• Key Metrics:
  • Revenue Growth: Look for consistent growth over the past 5 years.
  • Earnings Per Share (EPS) Growth: Shows that profitability is growing on a per-share basis.

This article provides a superb, concise pre-investment checklist with specific quantitative targets.

Part 3: The Qualitative Checklist: Understanding the Business

Numbers only tell part of the story. The qualitative checklist helps you assess the factors that don't appear on a balance sheet but are critical for long-term success.

Here are the key questions your qualitative checklist should answer:

1. Business Model & Competitive Advantage (Moat)

• Can you explain what the company does and how it makes money in simple terms? (If not, it might be outside your "circle of competence.")
• What gives it a durable competitive advantage, or "moat"? This could be a strong brand, unique technology, network effects, or cost leadership.

2. Management Quality & Corporate Governance

• Is the management team experienced and shareholder-friendly? Read the Chairman's message and Management Discussion in the annual report.
• Are there any governance red flags?

This article details several critical red flags to watch for.

3. Industry and Future Prospects

• Is the company in a growing or declining industry?
• What are the long-term trends affecting the business? (e.g., technological changes, new regulations, shifting consumer habits).

For a broad overview of what to look for in both quantitative and qualitative analysis, the following resource is helpful.

Action Item: Create Your Personal Stock Screening Checklist

Now it's your turn to synthesize this information. Your task is to create your own personal stock screening checklist. This is not a static document; it will evolve as you gain more experience. As the presenter in our first video noted, building and refining a checklist is an ongoing process.

Open a document or spreadsheet and create your checklist. I suggest you structure it in two sections:

Section 1: Quantitative Criteria (The Hard Filters)
List the key financial metrics you will use as your first-pass filter. For each metric, define a specific threshold. Use the Winvesta article's checklist as a starting point.

• Example:
  • Debt-to-Equity Ratio: Must be less than 1.0
  • Return on Equity (ROE): Must be greater than 15% for the last 3 years
  • Revenue Growth (5-Year Average): Must be positive

Section 2: Qualitative Criteria (The Key Questions)
List the critical questions you will ask about any company that passes your quantitative screen.

• Example:
  • Business Model: Can I explain how this company makes money in one sentence? (Yes/No)
  • Competitive Moat: What protects it from competition? (e.g., Brand, Scale, Patents)
  • Management Red Flags: Have there been recent auditor changes or resignations? (Yes/No)
  • Promoter Pledging: Is promoter share pledging below 5%? (Yes/No)

Remember to tailor this checklist to your own goals and risk tolerance. If your goal is long-term growth, you might be stricter on growth metrics. If your goal is income, you might add criteria about a company's dividend history.

Conclusion

Congratulations on building a foundational tool for your investment process. A well-defined checklist brings structure, discipline, and efficiency to your search for great companies. It helps you move from emotional decision-making to a systematic, rules-based approach—a trait common among successful long-term investors.

Key Takeaways:

• A stock screening checklist is a personal filter to narrow down investment candidates.
• It should be divided into quantitative criteria (financial metrics like ROE, D/E) and qualitative criteria (business model, management quality, competitive moat).
• Quantitative criteria act as a first-pass filter to ensure financial health, while qualitative criteria help you understand the story and long-term viability behind the numbers.
• Your checklist is a living document that you should refine and improve over time.

Now that you have your map, it's time to explore the territory. In our next lesson, we will apply the screening checklist you just created to filter stocks on the CSE and create a candidate list. We will look at practical tools available to Sri Lankan investors to run these screens and generate your first list of companies for deeper analysis.
