Every scoring system has two sides. The buy signal gets the attention — the excitement of discovering an undervalued company that meets every fundamental criterion. But the sell signal is where real money is protected. When a stock's Buffett Score drops below 35, it means the company is failing on multiple fundamental dimensions simultaneously. For Pro subscribers, this triggers a sell alert with a full breakdown of what changed and by how much.
Understanding what drives a score below 35 — and what it means in practice — is just as important as understanding what creates a score above 80. This article walks through the mechanics, the patterns, and the thinking behind the system's most critical threshold.
The Buffett Score evaluates six weighted criteria that together paint a picture of a company's fundamental health. A score below 35 does not happen because of one bad quarter or a single metric slipping. It requires broad, simultaneous deterioration across several dimensions. Here is how each criterion can degrade:
Profit margins compressing. When a company's gross or operating margins shrink over consecutive periods, it signals that pricing power is eroding. Perhaps competitors have entered the market, input costs have risen faster than the company can raise prices, or a once-dominant product is losing relevance. Margin compression is often the first visible sign that a company's competitive moat is narrowing.
Debt rising. A company that takes on significant debt — whether to fund an acquisition, cover operational shortfalls, or finance a capital-intensive pivot — will see its debt-to-equity ratio spike. When D/E climbs well above 0.5, the balance sheet becomes fragile. The company is increasingly dependent on continued cash flow to service its obligations, and any downturn in revenue creates a compounding problem.
Return on equity declining. ROE measures how efficiently the company converts shareholder capital into profit. When ROE drops year over year, it often means the business is deploying capital into lower-return projects, or that net income is falling faster than equity is being returned to shareholders. Declining ROE across multiple years is one of the strongest signals that a company's competitive position is weakening.
Free cash flow turning negative. Free cash flow is what Buffett calls "owner earnings" — the actual cash a business generates after maintaining its asset base. When FCF goes negative, the company is consuming more cash than it produces. It may still report positive earnings on paper, but the cash reality tells a different story. A business that cannot generate free cash flow cannot pay dividends, buy back shares, or invest in growth without borrowing.
Valuation becoming stretched. Even a fundamentally weak company can see its P/E ratio spike if earnings collapse faster than the stock price falls. A P/E ratio that is significantly above the company's own historical average and its industry peers means the market is still pricing in a future that the fundamentals no longer support.
When three or four of these criteria degrade simultaneously, the score drops rapidly. Below 35, the system is telling you that the company has moved far from the kind of business Warren Buffett would want to own.
The Buffett Score maps to five alignment bands, each representing a different relationship between a company's fundamentals and Buffett's investment principles:
A score below 35 is not a marginal call. It means the company has moved through Hold, through Watch, and into a zone where the weight of evidence suggests the fundamentals are deeply misaligned with what a disciplined value investor would accept.
While specific stock predictions are outside the scope of this article, the patterns that drive scores below 35 are recognizable and recurring. Here are three illustrative scenarios:
A company with a solid track record and strong margins decides to make a transformative acquisition, financing it primarily with debt. Overnight, the D/E ratio jumps from 0.3 to 1.8. The acquisition also brings integration costs that compress operating margins for several quarters. If the acquired business does not immediately generate enough cash flow to offset the debt service, free cash flow can turn negative. In a single transaction, three of the six criteria have degraded sharply — and the score follows.
A company in a cyclical industry — think commodities, industrials, or certain segments of consumer discretionary — enters the downward phase of its business cycle. Revenue falls, margins compress as fixed costs are spread over fewer units, and free cash flow turns negative as the company continues to invest in maintenance capital. ROE declines because net income has collapsed while the equity base remains roughly the same. The valuation metric may also deteriorate if the stock price does not fall as fast as earnings, pushing the P/E ratio to historically elevated levels. This is the scenario where multiple criteria fail simultaneously not because of bad management decisions, but because of macro conditions.
A company that was once a market leader sees its competitive advantage slowly dissolve. Margins compress year after year as competitors capture market share. ROE declines as the company invests more capital to defend a shrinking position. Free cash flow weakens as spending on retention, marketing, or product development increases without proportional revenue growth. This pattern is the most insidious because it happens gradually. Each year's decline is modest enough to dismiss, but over three to five years, the cumulative effect is severe. The Buffett Score captures this slow erosion because it evaluates current-period data against established benchmarks, not against last quarter alone.
Warren Buffett is famously reluctant to sell. His preferred holding period is "forever," and he has described the ideal business as one you never need to part with. But he has also been explicit about when selling is the right decision.
"Should you find yourself in a chronically leaking boat, energy devoted to changing vessels is likely to be more productive than energy devoted to patching leaks."
This quote, from one of his shareholder letters, captures the principle: when the fundamental nature of a business has changed — not a temporary setback, but a structural deterioration — the rational response is to move on rather than hope for a reversal.
Buffett has also articulated a simpler version of the selling rule: sell when the facts change. If the competitive advantage you believed in when you bought the stock no longer exists, the original investment thesis is invalidated. Holding on at that point is not patience — it is denial.
"When the facts change, I change my mind. What do you do, sir?"
The Buffett Score below 35 is a systematic, quantitative way of detecting when the facts have changed. It does not rely on narrative or sentiment. It measures the same six criteria that justified the purchase and tells you when they no longer hold.
When a stock's Buffett Score drops below 35, Pro subscribers receive a sell alert that includes more than just the headline number. The alert breaks down exactly which criteria degraded, by how much each one moved, and what changed since the previous scan.
This granularity matters because it informs the response. If the score dropped because a single one-time event crushed margins for one quarter, the appropriate action is different from a situation where ROE, margins, and free cash flow have all been declining for three consecutive scans. The alert gives you the data to make that distinction.
Pro subscribers also see the historical score trajectory — not just the current number, but how it has moved over recent scans. A stock that has been slowly drifting from 55 to 45 to 38 to 33 tells a very different story than one that dropped from 72 to 31 in a single period. The first suggests a structural decline; the second suggests a shock event that may or may not be temporary.
No scoring model is omniscient, and this one has specific blind spots that are important to acknowledge.
One-time write-offs. A company that takes a large non-cash impairment charge — writing down the value of an acquisition, for example — will see its net income and therefore its ROE and free cash flow drop dramatically for the quarter in which the charge is recognized. The score will fall. But write-offs are accounting events, not operating ones. The company's actual cash generation and competitive position may be completely unchanged. If the score drops because of a single non-recurring item, the next scan will likely show a recovery.
Cyclical troughs. For companies in cyclical industries, a low score at the bottom of the cycle is structurally different from a low score for a company in secular decline. The cyclical company's fundamentals will recover when the cycle turns. The model cannot distinguish between "this is the bottom of a cycle" and "this is the beginning of a permanent decline." That distinction requires understanding the industry and the company's position within it.
Restructuring periods. A company undergoing a genuine turnaround — selling off underperforming divisions, investing in a new strategic direction, taking short-term pain for long-term repositioning — will often see its score drop during the transition. If the restructuring succeeds, the score will recover. If it fails, the score was right to warn you. The model flags the deterioration; you must judge whether the cause is temporary or permanent.
This is where the Buffett Score is a starting point, not a final verdict. It systematically identifies fundamental deterioration. The question of whether that deterioration is transient or structural is one that requires human context, industry knowledge, and judgment. The score gives you the signal. What you do with it is up to you.
