4 Steps to Build The Best Munger/Buffett Stock Screener

You Can Easily Build a Great Munger/Buffett Stock Screener & Find Value Stocks By Applying Buffett's Investing Criteria With a Top Stock Screener

Table of Contents

Warren Buffett & Charlie Munger have proven over the last 50 years to be the most successful investors of all time.  With an average compound rate of return of 23.3% per year, Buffett and his good friend Charlie Munger have a reputation that Wall Street can only dream of. His wise investing has grown his company Berkshire Hathaway (BRK.A) into a behemoth worth over $500 billion.

But how did Buffett achieve these great investing returns?  He analyses stocks better than anyone else and understands what makes a great company.

The Warren Buffett Stock Screener

A Warren Buffett Stock Screener needs to filter on investing criteria such as earnings per share (EPS) growth, consistent return on equity (ROE), high return on invested capital (ROIC), and low debt using the solvency ratio. Finally, the screener needs to calculate the margin of safety using discounted cash flow (DCF).

How Does Buffett Screen for Stocks?

Buffett screens for stocks using specific criteria is the company profitable and generating a healthy cash flow.  He then predicts and discounts the cashflow ten years into the future. If the discounted cash flow value is 30% higher than the company’s stock market valuation, then it has a good margin of safety, and it is a candidate for purchase.

How To Build A Buffett Stock Screener

  1. Understand What Warren Buffett Looks For In Stocks
  2. Implement Those Metrics Into A Stock Screener
  3. Understand How Buffett Evaluates The Business & Industry

Section 1 is very detailed. If you do not want to read about all the criteria and methodology, jump directly to Section 2 – Implementing the Stock Screener


1. Warren Buffett Stock Selection Criteria

In this first step, we look at the key financial metrics to screen the stocks against.  The most detailed analysis of Buffett’s investing methodology is outlined in the book “The New Buffettology” by his daughter Mary Buffett.  We will use the Buffettology book, plus the two single most important criteria created by his mentor, the great Benjamin Graham, Fair Value (Intrinsic Value), and Margin of Safety.

Look for Fair Value Higher Than The Current Stock Price

Warren Buffett bases his Intrinsic Value / Fair Value calculations on future free cash flows. To explain, Buffett thinks cash is a company’s most important asset, so he tries to project how much future cash a business will generate and discount it against inflation. This is called the Discounted Cashflow Method.  Read more about Buffett’s Fair Value Calculation.

Screener Calculation – Fair Value 30% Higher Than Share Price

A High Margin Of Safety

Probably Buffett’s most important measure to decide whether to invest in a company.

Warren Buffet describes the Margin of Safety like this.

If you understood a business perfectly and the business’s future, you would need very little in the way of a margin of safety. So, the more vulnerable the business is, assuming you still want to invest in it, the larger the margin of safety you’d need. If you’re driving a truck across a bridge that says it holds 10,000 pounds and you’ve got a 9,800-pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay; but if it’s over the Grand Canyon, you may feel you want a little larger margin of safety…

The Margin of Safety is the percentage difference between a company’s Fair Value and its actual stock price. This metric is the single most significant valuation metric in our arsenal, as it is the final output of detailed discounted cash flow analysis.

A Strong Earnings Per Share History & Growth Rate

It will come as no surprise that earnings per share (EPS) is an important metric for Buffett and Wall Street.  Buffett looks for companies with a consistent track record of earnings growth, particularly over a 5 to 10 year period.

Screener Calculation – Yearly EPS growth Year on Year

A Consistently High Return on Equity

This is a profitability measure calculated as net income as a percentage of shareholders’ equity, also called ROE. A high ROE shows an effective use of investor’s money to grow the value of the business.

Screener Calculation – Return on Equity (ROE) 0> 15%

Does the Company Earn a High Return on Total Capital?

Return on Invested Capital (ROIC) quantifies how well a company generates cash flow relative to the capital it has invested in its business.

It is defined as Net Operating Profit after Taxes / (Total Equity + Long-term Debt and Capital Lease Obligation + Short-term Debt and Capital Lease Obligation)

Screener Calculation – 10 Year ROIC Average => 12%

Is the Company Conservatively Financed?

“For a company to pull out of any business difficulties it may encounter, it needs plenty of financial power.  Companies with a durable competitive advantage usually create such great wealth for their owners that they are long-term-debt-free or close to it. Standard debt-to-equity ratios give a poor picture of the business’s financial strength in that shareholder’s equity is seldom used to extinguish the debt. A business’s earning power is the only real measure of a company’s ability to service and retire its debt. You need to ask yourself, how many years of current net earnings would be required to pay off all the long-term debt of the business in the current year?”. Source The New Buffettology

To achieve this very specific calculation, you can use the closest match, the Solvency Ratio.

The solvency ratio is a measure of whether a company generates enough cash to stay solvent. It is calculated by summing net income and depreciation and dividing by current liabilities and long-term debt. A value above 20% is considered good.

Screener Calculation – Solvency Ratio > 20%

The Initial Rate of Return for the Stock is Greater than The Return on U.S. Treasury Bonds?

If a company cannot make a profit per share higher than the return of a safe asset like treasury bonds, you should not invest in it.  This is an easy calculation, and we will use the Earnings Yield.  Earnings Yield is the earnings per share for the most recent 12-month period divided by the current market price per share.

Screener Calculation -Earnings Yield > 3%

3. Understand How Buffett Evaluates The Business & Industry

There are certain factors that Buffett considers that are not found in the balance sheet or financials.  They are the business and competition-related questions that need a further deep dive.  Now that you have your potential target stocks in your screener window above.  Select a stock you like the look of, and ask the following Buffett questions as outlines in the Buffettology book.

Does the company have an identifiable durable competitive advantage?

The competitive advantage over others in the industry might be better technology, better products, patents, or even a captive market.  Does the company’s industry have high entry barriers, e.g., a microchip maker or telecoms company?  Also, do not forget, is a competitive advantage durable, meaning it will last for at least ten years.

Do you understand how the product works?

Buffett always says that if he does not understand how the product or service works, then he will not invest.  The idea is that if you cannot understand the business, you will not accurately assess potential threats or competition.  He wants to only invest money in companies he can understand.

If the company does have a durable competitive advantage and you understand how it works, then what is the chance that it will become obsolete in the next twenty years?

Does the company allocate capital exclusively in the realm of its expertise?

Is the company free to raise prices with inflation?

If the company has severe competition, which pushes product or service prices downward, this may be a stock to avoid.  If prices cannot increase with inflation, you may need to factor this into the valuation and Margin of Safety.

Are large capital expenditures required to update plant and equipment?

This question is aimed at companies that have to invest heavily in plant and equipment to remain competitive, for example, carmakers or telecoms companies.  These infrastructure upgrades can take a huge toll on debt and free cash flow.

Is the company’s stock price suffering from a market panic, a business recession, or an individual calamity that is curable?

This is the magic question and the question that leads to Buffett’s famous quote.

Be fearful when others are greedy, and be greedy when others are fearful

If the market is going through panic, a stock with great company fundamentals (financials), low competition, and a solid competitive advantage could see its stock price fall dramatically.  This would be a great time to buy, as you will see a higher Margin of Safety.

Is the company actively buying back its shares?

One sign Mr. Buffett looks for is companies buying back their own shares.  This usually means that the company’s management sees a bright future and also believes the stock market seriously undervalues the company.  This is often a good sign.

The best time to sell is never

Although not a strict rule, it pertains more to the fact that you need to buy and hold long-term.  If you have done your job well, you will not need to sell for the foreseeable future.
