Buffett-Style Stock Screen

What Is a Buffett-Style Screen?

Warren Buffett's investment framework has evolved significantly from his early Graham-influenced net-net and cigar-butt approach to the quality-at-fair-price philosophy he is associated with today. The shift is often credited to Charlie Munger and the 1972 purchase of See's Candies — a business with high returns on capital, pricing power, and minimal reinvestment needs. Buffett has described the insight as preferring "a wonderful business at a fair price over a fair business at a wonderful price."

A screen attempting to operationalize Buffett's criteria focuses on four dimensions: high returns on capital employed, earnings consistency over time, conservative use of debt, and an intrinsic value that is not wildly in excess of the current price. None of these are perfectly captured by a single metric, but the combination of ROIC, ROE, debt-to-equity, and multi-year earnings growth provides a reasonable quantitative approximation.

It is important to be honest about what this screen does not capture. Buffett's actual selection process is heavily qualitative: he is looking for durable competitive moats (brand, network effects, switching costs, low-cost producer advantages), management teams with integrity and capital allocation discipline, and businesses in industries he can understand and forecast over a 10–20 year horizon. A screen can surface candidates; it cannot perform qualitative analysis.

The companies that consistently meet this screen's criteria tend to be household names — consumer staples, industrial conglomerates, financial services franchises — because these are the sectors where pricing power and return on capital have historically been most durable. Technology companies also increasingly appear, though the capital-light nature of software businesses means some aggregated metrics look different than for traditional industrials.

The criteria in plain English:

• ROIC consistently above 15% — the business earns strong returns on deployed capital
• ROE above 15% — equity is being compounded at an attractive rate
• Debt-to-equity below 0.5 — the balance sheet is conservative
• Earnings growth positive over 3 years — the business is not in structural decline
• P/E below 30 — you are not paying a catastrophic price for these qualities

Buffett himself would resist any formula that purports to capture his approach. This screen is better understood as a filter that reduces a universe of thousands down to a manageable list of high-quality businesses worth investigating further.

How to Run This Screen in GeminIQ

Step 1. Open the GeminIQ Screener

Step 2. Add the following filters:

Filter	Operator	Value
ROIC TTM	≥	15
ROE TTM	≥	15
Debt To Equity	≤	0.5
Net Income TTM Growth 3Y	≥	8
P/E TTM	≤	30
P/E TTM	≥	1

Step 3. Set Sort By to ROIC TTM, direction Descending — highest quality first.

Step 4. For each result, open the company's Financial Statements in GeminIQ and review:

• Is ROIC stable or improving over the past 8 quarters?
• Is revenue growth organic or acquisition-driven?
• Are there significant off-balance-sheet obligations (operating leases, pension liabilities)?

GeminIQ Tip: Use the Calculated Metrics trend view to verify that ROIC and ROE are stable over multiple periods, not a function of a single good quarter. Buffett-style quality is defined by consistency — a business that earns 20% ROIC reliably is more valuable than one that earns 35% one year and 5% the next.

What Aggregator Data Misses for This Screen

This screen is particularly sensitive to how aggregators handle ROIC and ROE, since those are the primary quality signals.

Goodwill and intangible assets in invested capital. When a company grows through acquisitions, goodwill and acquired intangibles accumulate on the balance sheet. Many aggregators include goodwill in invested capital, which suppresses ROIC for acquisitive companies. Some aggregators strip goodwill out, which makes ROIC look higher. Buffett himself focuses on return on tangible equity — a metric that strips goodwill — precisely because it measures how well the underlying business compounds capital. GeminIQ reports invested capital as-filed, so you can see goodwill as a separate balance sheet line and calculate both variants.

Pension obligations. Companies with large defined-benefit pension plans carry off-balance-sheet-equivalent obligations that affect the true leverage picture. While US GAAP requires pension liabilities on the balance sheet since SFAS 158, the discount rate assumptions used to calculate the obligation vary by company and can significantly affect both the liability and the annual pension expense flowing through earnings. An aggregator applying a normalized discount rate will produce different ROE and debt-to-equity figures than the as-filed data. GeminIQ uses the company's own reported figures.

Stock-based compensation. High-ROIC technology companies often carry significant stock comp expense. Some aggregators add this back in adjusted earnings, making ROE and earnings growth look better than the as-filed numbers. GeminIQ surfaces as-filed net income, and the Stock Comp To Revenue TTM metric lets you explicitly see what share of revenue is being distributed as equity compensation — a useful context for any quality screen.
