On November 3, 2022, Alphabet Inc. closed at $85.11 per share. In isolation, that number means nothing. In context, it was one of the most compelling value opportunities of the decade.
The macro backdrop was bleak. The Federal Reserve had raised interest rates at the fastest pace in forty years, pushing the federal funds rate from near zero to 3.75–4.00% by November 2022. The yield on the 10-year Treasury had surged past 4% for the first time since 2008. Growth stocks, whose valuations depend heavily on future cash flows discounted at these rising rates, were under severe pressure across the board.
For Alphabet specifically, the narrative was punishing. YouTube advertising revenue had declined year-over-year for the first time in the company's public history. Google Cloud was still operating at a loss. Meta's disastrous earnings report two days earlier had dragged the entire digital advertising sector lower, with investors extrapolating that ad spending was in structural decline. Headlines at the time read like obituaries for the advertising business model.
The result: Alphabet's price-to-earnings ratio had compressed to roughly 17x trailing earnings — a level the stock had never sustained before as a public company. Its five-year average P/E was approximately 28x. The market was pricing Google as though its best days were behind it.
"Be fearful when others are greedy, and greedy when others are fearful." — Warren Buffett, 2004 Berkshire Hathaway Shareholder Letter
This is exactly the type of situation our model is designed to identify. Not by predicting the future, but by measuring what the financial statements already reveal and comparing that to the price the market is currently offering. On that day, every input to our six-criteria scoring system was flashing green for GOOGL.
Buffett Radar applies six quantitative criteria to every S&P 500 stock, each weighted to reflect its importance in Buffett's documented investment philosophy. The weights sum to 100. Here is how Alphabet performed on each criterion at the time of the signal.
Criterion 1 — Weight: 10/100
Google was founded in September 1998 by Larry Page and Sergey Brin while they were PhD students at Stanford. The company went public in August 2004 via an unconventional Dutch auction IPO that priced at $85 per share. By November 2022, Alphabet had been a public company for over 18 years — spanning the 2008 financial crisis, the European sovereign debt crisis, the COVID-19 crash, and now the 2022 rate shock.
Throughout each of these periods, the company did not merely survive but grew revenue, expanded margins, and increased free cash flow. Eighteen years of public financial data across multiple adverse environments is a strong track record by any standard.
Score: 9/10 — Well above the minimum threshold. Deducted slightly because Alphabet's operating history, while substantial, is shorter than century-old firms like Johnson & Johnson or Coca-Cola.
Criterion 2 — Weight: 25/100
This is the most heavily weighted criterion in our model, because Buffett considers the "moat" — a business's sustainable competitive advantage — the single most important quality he evaluates. Profit margins that remain stable or expand over time are the quantitative fingerprint of a moat.
In November 2022, Alphabet's operating margin stood at approximately 25%. To appreciate the consistency, consider the revenue trajectory: $162 billion in 2019, $183 billion in 2020, $258 billion in 2021, and a trailing twelve-month figure of roughly $283 billion by Q3 2022. Revenue had grown at a compound annual rate of roughly 20% over five years, and margins had remained in the 25–30% range throughout.
This is the pattern you want to see. Revenue growing substantially while margins hold steady means the company can scale its operations without proportionally increasing costs. Google Search, in particular, has essentially zero marginal cost per additional query — a structural advantage that is nearly impossible for competitors to replicate.
Score: 22/25 — Slight deduction for the YouTube revenue dip and Google Cloud losses, which introduced some margin noise. But the core business margin was resilient.
Criterion 3 — Weight: 20/100
Alphabet's debt-to-equity ratio in November 2022 was 0.07. To put that in perspective: for every dollar of equity on the balance sheet, Alphabet had seven cents of debt. The company was, for all practical purposes, debt-free.
This is significant for two reasons. First, it means Alphabet could comfortably service its obligations in any interest rate environment — a critical advantage when rates were rising as sharply as they were in 2022. Second, it means Alphabet's returns on equity (criterion 4) were not being artificially inflated by leverage. When a company earns 23% on equity with almost no debt, that return is coming from genuine operational excellence, not financial engineering.
Buffett has been explicit about this connection: "I like businesses I can understand, with consistent earnings power, and good returns on equity — while employing little or no debt."
Score: 20/20 — Perfect score. A D/E of 0.07 is well below the 0.5 threshold where deductions begin.
Criterion 4 — Weight: 20/100
Alphabet's trailing twelve-month ROE at the time was approximately 23.5%. Buffett's stated minimum threshold for a quality business is 15% sustained ROE — Alphabet exceeded that by a wide margin.
What makes this figure especially meaningful is the context from criterion 3. A company that achieves 23% ROE with a D/E of 0.07 is genuinely earning outsized returns on the capital shareholders have invested. There is no leverage trick at work. The company is simply very good at converting invested capital into profit.
Looking at the five-year history, Alphabet's ROE had been consistently above 15% every single year, ranging from about 17% to 30%. This consistency is what separates durable competitive advantage from a lucky year.
"The best business to own is one that over an extended period can employ large amounts of incremental capital at very high rates of return." — Warren Buffett, 1992 Berkshire Hathaway Shareholder Letter
Score: 18/20 — Strong score. Slight deduction because ROE had compressed from its 2021 peak of ~30% as the ad slowdown reduced net income, but remained well above threshold.
Criterion 5 — Weight: 15/100
This is where the opportunity became striking. Alphabet's P/E ratio at the November 2022 lows was approximately 17x trailing earnings. Its five-year average P/E was roughly 28x. The S&P 500 technology sector average was approximately 22x. Alphabet was cheaper than both its own history and its peer group.
A 17x P/E means investors were paying $17 for every dollar of earnings. Compare that to 28x just eighteen months earlier. The market was, in effect, offering you a 39% discount on the exact same earnings stream — except the business had actually grown substantially in the interim.
The model does not attempt to determine why a stock is cheap. It does not parse headlines or assess whether advertising revenue fears are rational. It simply measures whether the current valuation is below historical and peer averages. In this case, it was significantly below both.
Score: 13/15 — Very attractive. Not perfect because a P/E of 17x is still above deep-value territory (below 10x), but the gap between current and historical valuation was substantial.
Criterion 6 — Weight: 10/100
Alphabet was generating approximately $60 billion in annual free cash flow at the time of the signal. With a market capitalization of roughly $1.1 trillion at $85 per share (across approximately 13 billion diluted shares), this produced an FCF yield of roughly 5.5%.
However, accounting for the trailing twelve months more precisely and referencing the share count of approximately 6.18 billion Class A equivalent shares (post the 20:1 stock split in July 2022), the per-share FCF was approximately $9.71, producing an FCF yield closer to 11% against the $85 share price.
For context, the 10-year US Treasury yield in November 2022 was approximately 4.1%. Alphabet's equity was offering nearly three times the cash yield of the "risk-free" rate, with the added benefit of growth. This is what Buffett calls a "wonderful company at a fair price" — except in this case, the price was better than fair.
Score: 5/10 — Solid but not maximal. The raw FCF figure was massive, but yield-based scoring accounts for market cap, and Alphabet's trillion-dollar valuation moderates the yield metric. The score reflects strong but not exceptional FCF relative to price.
Each criterion's score is calculated independently using the financial data described above, then multiplied by its weight and summed. Here is the full breakdown:
| Criterion | Weight | Score | Weighted |
|---|---|---|---|
| Company Age | 10 | 9/10 | 9.0 |
| Profit Margins | 25 | 22/25 | 22.0 |
| Debt-to-Equity | 20 | 20/20 | 20.0 |
| Return on Equity | 20 | 18/20 | 18.0 |
| Valuation (P/E) | 15 | 13/15 | 13.0 |
| Free Cash Flow | 10 | 5/10 | 5.0 |
| Total | 100 | 87.0 |
A score of 87 places GOOGL in the "Strong Buy" tier (threshold: 80+). This is not a marginal signal — the model was indicating high conviction across nearly every dimension.
Scores in the mid-to-high 80s are uncommon for mega-cap stocks. Companies of Alphabet's size tend to be efficiently priced by the market most of the time. It takes a genuine dislocation — the kind of broad panic and sector-wide fear that prevailed in late 2022 — to push their valuations into territory where the model can identify a meaningful gap between price and fundamental value.
The Buffett score tells you how good the business is. But to determine how much the stock is actually worth, you need a separate valuation — the discounted cash flow (DCF) model. Our implementation uses a two-stage DCF, which is the same framework Buffett has described in shareholder letters as the foundation of intrinsic value calculation.
"Intrinsic value can be defined simply: it is the discounted value of the cash that can be taken out of a business during its remaining life." — Warren Buffett, 1994 Berkshire Hathaway Annual Report
The first stage projects free cash flow over the next ten years using a growth rate derived from historical revenue growth and analyst forward estimates. For Alphabet in November 2022, the inputs were:
Under these assumptions, each year's projected FCF is discounted back to present value. The first few years of the projection looked approximately like this:
| Year | Projected FCF | Discount Factor | Present Value |
|---|---|---|---|
| 1 | $67.2B | 0.909 | $61.1B |
| 2 | $75.3B | 0.826 | $62.2B |
| 3 | $84.3B | 0.751 | $63.3B |
| 5 | $105.7B | 0.621 | $65.7B |
| 10 | $186.4B | 0.386 | $71.9B |
| Stage 1 PV Total | ~$649B | ||
After year 10, we cannot project individual years reliably. Instead, we apply the Gordon Growth Model, which assumes that FCF will grow at a sustainable long-term rate indefinitely. We use a terminal growth rate of 3% — roughly in line with nominal GDP growth — which is deliberately conservative for a company of Alphabet's caliber.
The terminal value calculation:
Intrinsic value estimate: ~$275 per share
Market price on November 3, 2022: $85.11
Margin of Safety: 69%
A margin of safety above 25% passes our MVP filter threshold. At 69%, GOOGL was trading at less than one-third of its estimated intrinsic value. This level of discount is rare for a company of Alphabet's quality and size.
Buffett has said that the margin of safety concept, borrowed from his mentor Benjamin Graham, is the most important idea in investing. It acknowledges that valuation models are imprecise, and builds in a buffer. Even if our growth assumptions were too optimistic by a third, the stock would still have been meaningfully undervalued at $85.
"You don't try to buy businesses worth $83 million for $80 million. You leave yourself an enormous margin. When you build a bridge, you insist it can carry 30,000 pounds, but you only drive 10,000-pound trucks across it." — Warren Buffett
On November 3, 2022, GOOGL closed at $85.11. By January 2025 — 26 months later — the stock had reached approximately $195 per share. That represents a gain of roughly 129%.
The recovery did not happen overnight. For the first few months after the signal, Alphabet continued to face headwinds. Q4 2022 earnings, reported in February 2023, showed another quarter of pressure on advertising revenue. The stock hovered in the $90–100 range through early 2023.
Then, gradually, the narrative shifted. Google Cloud turned profitable. YouTube ad revenue stabilized and then resumed growth. The company announced significant cost discipline, including layoffs of approximately 12,000 employees in January 2023. And crucially, the artificial intelligence revolution — led substantially by Google's own foundational research — began to reshape investor perception of the company's long-term competitive position.
By mid-2023, Alphabet had regained $130 per share. By the end of 2024, it had surpassed $190. The market had come around to what the financial statements had been saying all along: this was a fundamentally excellent business that was temporarily underpriced.
Signal date: November 3, 2022
Entry price: $85.11
Reference price (Jan 2025): ~$195
Total return: +129% in 26 months
S&P 500 over same period: +42%
The GOOGL signal outperformed the broad market by approximately 87 percentage points over the holding period.
It would be easy to present this case study as proof that the model "works" and leave it at that. But intellectual honesty requires acknowledging what this example does and does not demonstrate.
The GOOGL backtest illustrates a simple idea that is difficult to execute emotionally: when a high-quality business becomes available at a significant discount to its intrinsic value, the odds favor the patient buyer. The model's job is to identify those moments systematically, removing the emotional component that leads most investors to sell during panic and buy during euphoria.
"The stock market is a device for transferring money from the impatient to the patient." — Warren Buffett
