A Retired Economist’s Struggle with U.S. Stocks
When a Great Story Becomes a Profitable Business
Story → High Revenue Growth → Break-Even → Operating Leverage → Earnings Growth → Revaluation
In stock investing, a company whose share price rises tenfold is commonly called a “tenbagger.” Finding a stock that has already risen tenfold is not difficult. The real challenge is identifying, among the many companies with compelling stories but continuing losses and skeptical investors, those whose share prices may truly rise more than tenfold in the future.
In Article 15, we examined several ways to find tenbaggers. One type is particularly interesting: a loss-making company that maintains rapid revenue growth while its profit structure improves, and that also possesses a technological or business moat that competitors cannot easily replicate.
Turning profitable means more than simply eliminating losses. At a high-growth company, if revenue keeps rising while the rate of cost growth begins to slow, profits can grow far faster than revenue. This is operating leverage. At that point, the market begins to revalue the company from “a story that might make money someday” into “a business that can grow while making money.”
Of course, some companies see their stocks rise first on the strength of the story alone, and another approach is to apply leverage to long-term winners through products such as TQQQ and SOXL. But this article focuses on one question: “If we had bought a loss-making company with high growth and a moat as it crossed the inflection point in its profit structure, would it actually have become a tenbagger?”
1. First, Let Us Define What ‘Turning Profitable’ Means
There is no single accounting definition of a turn to profitability. The timing differs depending on whether we look at net income, operating income, adjusted EBITDA, or free cash flow. The five cases in this article are not identical. Palantir turned to positive GAAP net income in 2023, Amazon reported annual net income in 2003, and Tesla achieved positive annual GAAP net income in 2020. Carvana reported positive GAAP net income in 2023, although debt-reduction gains contributed to the result. Bloom Energy, meanwhile, turned to positive annual GAAP operating income in 2024, while net income remained negative.
Accordingly, “turning profitable” in this article does not mechanically mean that EPS has crossed above zero. It refers to an “inflection point in the profit structure,” when losses in the core business are shrinking rapidly and one or more of operating income, cash flow, and net income turns structurally positive.
| Company | Inflection Point (Profitability Year) | Confirmed Change | Caution |
| Palantir | 2023 | GAAP net income $210M | Monitor government exposure and stock-based compensation |
| Bloom Energy | 2024 | GAAP operating income $22.9M | Net income still negative |
| Carvana | 2023 | GAAP net income $150M | Debt-reduction gains contributed |
| Amazon | 2003 | Annual net income $35M | Cost structure improved after dot-com collapse |
| Tesla | 2020 | GAAP net income attributable to common stockholders $721M | Consider contribution from regulatory credits |
2. Why Can the Stock Remain Depressed Until Just Before the Turn to Profitability?
Early-stage high-growth companies spend heavily up front on R&D, production capacity, sales organizations, and logistics networks to capture the market. Even when revenue grows 30–50%, persistent losses lead investors to ask, “So when will this company actually make money?”
Palantir, Bloom Energy, and Carvana all had compelling growth stories, yet each spent periods below its listing price before the improvement in profitability was confirmed. Amazon’s survival was questioned after the dot-com crash, while Tesla remained unprofitable for years amid production delays and financing concerns.
But once revenue at a company with substantial fixed costs crosses a critical threshold, the incremental cost of generating one additional dollar of revenue can become far less than one dollar. Revenue growth of 20% can then translate into operating-profit growth of 50% or even 100%. This is the zone in which stock-price revaluation can be most dramatic.
3. The Profitability Inflection Point and Stock Prices of Five Companies
| Company (Profitability Year) | Start of Inflection Year | Year-End | Gain That Year | Sep. 30, 2026 / Start of Inflection Year |
| Palantir (2023) | $6.39 | $17.17 | +168.7% | 29.3x |
| Bloom Energy (2024) | $14.76 | $22.21 | +50.5% | 18.8x |
| Carvana (2023) | $0.93 | $10.59 | +1,038.7% | 67.2x |
| Amazon (2003) | $0.94 | $2.63 | +179.8% | 265.1x |
| Tesla (2020) | $27.89 | $235.22 | +743.4% | 12.7x |
The striking point is that all five stocks had already moved sharply during the year in which their profit structures changed. Even Bloom Energy, the weakest performer of the five, rose about 50%, while Carvana surged more than tenfold. In other words, waiting until profitability is fully confirmed can mean missing a substantial part of the advance.
Even more interesting, comparing the price at the beginning of the inflection year with the price at the end of September 2026 shows that all five examples rose more than tenfold. This does not mean that turning profitable is a sufficient condition for becoming a tenbagger. There is survivor bias because we are looking backward at companies that succeeded. What we are testing is whether a shift in the profit structure can be a powerful revaluation signal when high growth and a moat are already present.
4. Revenue Growth Alone Is Not Enough — The Quality of Revenue Must Change
| Company | Revenue / Business Change Around the Inflection Point | Key Point |
| Palantir | 2020 revenue +47% → 2023 +17% → 2024 +29% → 2025 +56% | Growth reaccelerated after profitability |
| Bloom Energy | 2024 $1.47B (+10.5%) → 2025 $2.02B (+37.3%) | Margin improvement + AI power demand |
| Carvana | 2023 revenue $10.77B, down | Unit economics and cost structure improved first |
| Amazon | 2003 revenue $5.26B, +33.8% | Economies of scale and cash-flow improvement |
| Tesla | 2020 revenue $31.54B, +28.3% | Mass production translated into profits |
Carvana is an important counterexample. Its 2023 turn to profitability did not coincide with rapid revenue growth; instead, revenue declined while unit economics and the cost structure improved sharply. The formula, therefore, is not simply “30% revenue growth + profitability.” A more accurate signal is whether gross profit and the cost structure are improving together while the company’s growth potential remains intact.
4-1. Before, During, and After the Turn to Profitability — What Happened to Stock Prices and Revenue?
Dividing the five companies into the same three periods makes the significance of the profitability inflection point clearer. In the more recent cases—Palantir, Bloom Energy, and Carvana—share prices were stagnant or declining until just before the inflection point. Amazon and Tesla, by contrast, had already posted strong long-term share-price gains before becoming profitable. Turning profitable, therefore, is not the starting point of every tenbagger. Rather, it can be an especially powerful revaluation signal for a high-growth company whose profitability the market still doubts.
| Company | Listing/Early Period → Start of Inflection Year Stock-Price CAGR | Inflection Year Stock-Price Gain | Inflection Year-End → Sep. 30, 2026 Stock-Price CAGR | Interpretation |
| Palantir | Approx. -5% | +168.7% | Approx. +138% | Revaluation after loss and growth-slowdown concerns |
| Bloom Energy | Approx. 0% | +50.5% | Approx. +323% | Revaluation after long stagnation, margin improvement, and AI power demand |
| Carvana | Approx. -19% | +1,038.7% | Approx. +91% | Sharp reversal in unit economics after bankruptcy fears |
| Amazon | Approx. +57% | +179.8% | Approx. +22% | Hypergrowth even before profitability, then long-term compounding |
| Tesla | Approx. +40% | +743.4% | Approx. +7% | Growth before profitability; major revaluation in 2020 |
Revenue is even more important than the stock price. Comparing how much revenue had already grown before the turn to profitability—and whether revenue continued to grow afterward—helps distinguish a structural improvement at a growth company from profitability created merely by cost cutting.
| Company | Listing/Early Period → Pre-Inflection Revenue CAGR | Inflection Year Revenue Growth | Post-Inflection Revenue CAGR | Key Point |
| Palantir | 2020→22 approx. +32% | 2023 +16.7% | 2023→25 approx. +41.8% | Growth reaccelerated after profitability |
| Bloom Energy | 2018→23 approx. +12.4% | 2024 +10.5% | 2024→25 +37.3% | Growth reaccelerated with margin improvement |
| Carvana | 2017→22 approx. +73.8% | 2023 -20.8% | 2023→25 approx. +37.4% | Growth resumed after restructuring |
| Amazon | 1997→02 approx. +92.8% | 2003 +33.8% | 2003→25 approx. +25.0% | Long-term compounding after hypergrowth |
| Tesla | 2010→19 approx. +81.2% | 2020 +28.3% | 2020→25 approx. +24.6% | Growth continued after mass production |
** Post-inflection CAGR is calculated through the latest comparable annual results (2025). The figures incorporate 2025 revenue of $4.48B for Palantir (+56%), $2.02B for Bloom Energy (+37.3%), $20.32B for Carvana (+49%), $716.9B for Amazon (+12%), and $94.83B for Tesla (-3%).
Taken together, the two tables make the central point clearer. A stronger signal than profitability itself is whether revenue reaccelerates or remains high after the company turns profitable. This pattern is particularly clear in Palantir and Bloom Energy. Carvana’s revenue declined in the year it turned profitable, but growth revived in 2024–2025 after unit economics improved sharply. By contrast, profitability created solely by cost cutting while revenue growth is deteriorating is difficult to regard as a tenbagger signal.
5. The Five Companies Have Very Different Moats
| Company | Core Moat | Why It Is Difficult to Replicate |
| Palantir | Ontology · Foundry · AIP | Deep integration into core customer data and workflows; high switching costs |
| Bloom Energy | Solid oxide fuel cells · On-site power | Technology and manufacturing experience enabling rapid deployment of large-scale power without waiting for grid connections |
| Carvana | Vertical integration of sales · purchasing · logistics · inventory · finance | Requires a nationwide logistics network, vehicle data, and unit economics to be built simultaneously |
| Amazon | Flywheel of customers · sellers · logistics · Prime · AWS | Greater scale improves both cost and service |
| Tesla | Vertical integration of EVs · batteries · software · manufacturing | Combines product, factory, and software data to reduce costs |
A “technological moat” does not mean a single patent. It can be software embedded deeply in a customer’s workflow, as with Palantir, or manufacturing technology that allows real products to be deployed rapidly, as with Bloom Energy. An operating system that combines technology, logistics, and data—as in Carvana and Amazon—can also be an important moat.
6. Four Numbers to Watch Before Profitability
| Checkpoint | Positive Signal | Warning Signal |
| ① Revenue | 20–30%+ growth or reacceleration | Persistent growth slowdown |
| ② Gross Margin | Rising or remaining high | Margins deteriorate as revenue grows |
| ③ Operating Expenses | Grow more slowly than gross profit | Grow faster than revenue |
| ④ Cash Flow | Operating cash flow / FCF improves first | Cash burn continues despite accounting profits |
When all four numbers improve together, break-even stops being a vague hope and becomes an event with a rising probability. The key moment is when gross-profit growth begins to consistently outpace operating-expense growth.
7. The Biggest Trap — Five Success Stories Are Not Enough
The biggest weakness in this analysis is survivor bias. We are looking backward at Palantir, Bloom Energy, Carvana, Amazon, and Tesla—companies that ultimately succeeded. In reality, far more companies claim that profitability is just around the corner, only to see revenue slow and survive through repeated share issuance before eventually disappearing.
The first profit can also be temporary. Carvana’s 2023 net income benefited from gains related to debt reduction. Bloom Energy turned to positive operating income in 2024 but still reported a net loss. Tesla’s 2020 earnings should also be viewed alongside the contribution from regulatory credits.
The real signal, therefore, is not the “first profit” but repeatability. Revenue must continue to grow the following year, gross margin must hold up, operating cash flow must improve, and the company must be able to finance growth without excessive additional share issuance.
8. A Practical Filter for Finding Tenbagger Candidates
| Step | Question | Example of a Passing Signal |
| 1 Market | Is the addressable market large enough if the company succeeds? | Room for revenue to grow severalfold |
| 2 Growth | Is revenue actually growing rapidly? | 20–30%+ or reaccelerating growth |
| 3 Moat | Can competitors easily replicate it? | Technology · data · network effects · switching costs |
| 4 Unit Economics | Does the economics improve with scale? | Improving gross margin · GPU · profit per customer |
| 5 Leverage | Is gross profit growing faster than costs? | Operating-loss margin keeps narrowing |
| 6 Cash | Does improving profitability translate into cash? | Improving operating cash flow / FCF |
| 7 Price | Is all the success already priced in? | Further upside if growth persists |
9. Conclusion — When a Great Story Becomes Great Numbers
Palantir, Bloom Energy, Carvana, Amazon, and Tesla operate in entirely different industries and have very different business models. Yet they share one characteristic: before turning profitable, each already had a large addressable market and a growth story, while investors still questioned whether the company could truly make money.
Once that doubt began to be resolved by the numbers, their share prices moved very quickly. But this should not be read as “buy companies when they turn profitable and they will become tenbaggers.” The sequence is the reverse. First there must be a large market, high growth, and a moat that competitors cannot easily overcome. Next, gross margin and cash flow must improve. Finally, the turn to profitability confirms the economics of the business model.
A more important question than ‘When will this company turn profitable?’ is
‘Is revenue continuing to grow while costs rise more slowly—and is that structure difficult for competitors to replicate?’
When the answer to both questions begins to become “yes,” the next tenbagger may already be emerging inside the income statement of a company that is still reporting losses.
