Investing Classics: Energy & CyclicalsEnergy, Commodities, and the Logic of Cycles
June 5, 2026·BigCat's Capital Allocator
Cyclicals — oil, metals, energy — follow a logic utterly unlike that of consumer or tech stocks: their fate is governed by supply, demand, and the price cycle, not by compounding. This issue unpacks four dimensions — the reflexive oil cycle, the "capital cycle" behind metals and smelting, the "a world-changing trend is not a good business" trap of energy transition, and the nature of commodities as "non-productive assets." The goal isn't to time the market, but to give you a mental framework for cyclical assets.
The Capital Cycle: The Real Engine of Cyclical Returns
Phase
What's happening
What smart money does
① Boom
High prices, fat profits; capital and new capacity flood in
Be wary, step aside — where all are optimistic, returns are being spent in advance
② Glut
New capacity comes online, supply catches demand, prices peak and roll over
Sell out; don't be fooled by a low P/E on peak earnings
③ Shakeout
Prices crash, the industry loses money, capex is slashed, bankruptcies follow
Buy the low-cost survivors against the crowd
④ Recovery
Supply shrinks, capacity is short, prices climb back
Harvest — and prepare to exit again in the next boom
Most people stare at demand forecasts; the real money hides on the supply side — where capital flees, returns are being born.
PRINCIPLE 01 · Oil Cycle
Price Self-CorrectsThe Cure for Low Prices Is Low Prices
Cyclical reflexivity
The Principle
Commodity prices self-correct: high prices spur production and suppress demand, eventually crushing the price; low prices do the reverse. Cycles can't be abolished — all you can do is recognize where you stand in one.
Source + Quote
"The cure for high prices is high prices, and the cure for low prices is low prices."
— Commodity-market adage, often cited by cycle thinkers such as Howard MarksPrice itself is the force that regulates supply and demand — and ends its own extremes.
Deeper Reading
The most counterintuitive feature of cyclicals: the valuation signal is inverted. Peter Lynch warns in One Up on Wall Street that when a cyclical's P/E is very low and earnings are at a record, it is often the tail end of the boom — because peak earnings make the P/E look "cheap" just as earnings are about to revert to the mean. This is especially true of oil: when prices are high, shale and deepwater projects pile in, and two or three years later the supply gushes out and prices collapse. The correct anchor isn't the current P/E, but where the commodity price sits relative to the long-run marginal cost of production.
Classic Case
In June 2014 WTI crude was about $107/barrel; the US shale revolution surged output, OPEC refused to cut, and by February 2016 it had fallen to about $26 (−76%). More extreme still was April 20, 2020: lockdowns evaporated demand and storage ran out, and the WTI May contract closed at a negative price for the first time in history — −$37.63/barrel, meaning longs had to pay to take delivery. Both crashes proved the same point: however "cheap" oil looks, it can get cheaper.
Limits + Decision Checklist
Cycles can be broken by structural change — if demand is permanently displaced, low prices need not rebound, and a "cycle" becomes a "secular decline." Misuses: ① running a DCF on peak earnings as if they were normal; ② buying a low P/E to bottom-fish a cycle that's actually topping; ③ ignoring the balance sheet — a company that can't survive the trough has no "rebound."
Relative to long-run marginal cost of production, is the commodity price high or low?
Am I being misled by a "low P/E" while earnings sit at the cycle peak?
Can this company's balance sheet survive one full price trough?
Is demand cyclically dipping, or structurally and permanently shrinking?
Essence
For cyclicals, read cheap and dear backwards — the most dangerous entry point usually looks the most like a bargain.
This Week's Reflection
Look back at any "cyclical" asset you've held. Did you judge by where the price stood in the cycle, or were you drawn in by a P/E that merely looked very low?
PRINCIPLE 02 · Metals & Smelting
The Capital CycleSupply Is What Matters
Supply-side thinking
The Principle
What decides a cyclical's long-run returns is often not demand but supply — and supply is driven by the "capital cycle": industries that capital floods into see returns fall, while those capital flees see returns recover.
Source + Quote
"The prospect of high returns will attract excessive capital and competition, and vice versa."
— Edward Chancellor, ed., Capital Returns (2016), the Marathon Asset capital-cycle frameworkThe whole of capital-cycle analysis rests on this plain proposition.
Deeper Reading
Marathon Asset's "capital cycle" framework upends common sense — most people stare at demand forecasts, while the real money comes from the supply side. The loop: high prices → high profits → capital pours in → glut → price crash → losses and bankruptcies → capital flees, capacity is shaken out → supply shrinks → prices recover. The investor's job is to run against the capital cycle: build positions when capex has dried up and everyone has left; step aside amid expansion mania. The key metric is industry-wide capex and new capacity, not a single quarter's demand.
Classic Case
2003–2011, the "China super-cycle": urbanization devoured the world's metals, and iron ore climbed from about $30/tonne to roughly $190 by early 2011, as the big three miners and countless new projects expanded furiously on the logic that "China demand never stops." But supply finally caught up — by end-2015 iron ore had fallen back to about $40 (−79%). Capital that expanded at the top was almost wiped out; those who entered after the 2015–2016 shakeout caught the subsequent rebound.
Limits + Decision Checklist
The capital cycle demands patience and can't be timed precisely — a shakeout may drag on for years, and being early is agonizing. It also assumes the industry is ultimately rational, but subsidies, state-owned firms, and strategic-industry status can keep capacity that "should die" alive, distorting the whole cycle.
Is this industry expanding furiously right now, or cutting capex and shutting capacity?
Am I following capital in, or positioning against it as capital flees?
Are there subsidies or policies that keep inefficient capacity from exiting, distorting the normal cycle?
Essence
Many watch demand; those who profit usually watch supply — where capital flees, returns are being born.
This Week's Reflection
An industry you follow — is capital pouring in right now, or is no one interested? What does that fact alone imply about future returns?
PRINCIPLE 03 · Energy Transition
A Great Trend ≠ A Good BusinessA World-Changing Trend Is Not a Good Investment
The growth trap
The Principle
A world-changing trend is not the same as a money-making business. Growth without pricing power and returns on capital becomes a black hole that devours capital.
Source + Quote
"The worst sort of business is one that grows rapidly, requires significant capital to engender the growth, and then earns little or no money. Think airlines."
— Warren Buffett, Berkshire 2007 Letter to ShareholdersA durable competitive advantage in such industries has proven elusive ever since the Wright Brothers.
Deeper Reading
The energy transition is almost certainly one of the largest trends of the coming decades — but "the trend is right" and "the investment is right" are two different things. Buffett uses autos and airlines to make the point: of the roughly 2,000 American carmakers of the early 20th century, nearly all vanished; aviation changed the world yet cumulatively destroyed enormous shareholder value. The reason is that these industries grow fast but sell commodities, lack pricing power, and have bottomless capex. Solar modules are the textbook case: technical progress crashed costs, capacity became massively oversupplied, and manufacturing degenerated into a thin-margin "commodity," with the trend's dividend captured by consumers and latecomers rather than early shareholders.
Classic Case
Amid the 2010s solar boom, SunEdison expanded via aggressive debt-funded acquisitions and briefly became the world's largest renewable-energy developer; in April 2016 it filed for bankruptcy under roughly $16 billion of debt — one of the largest US bankruptcies of that year. Countless early solar manufacturers fell amid overcapacity and price wars. Solar generation grew dozens-fold over the decade, yet most early investors in manufacturing got nothing — the growth was real, the returns were not.
Limits + Decision Checklist
This isn't to say transition industries are uninvestable — rather, find the links in the chain with pricing power and cost barriers (specialized equipment, key materials, concession-type operating assets), and avoid commoditized manufacturing. Misjudgment usually comes when "the story is too compelling" overrides a cool look at unit economics.
Does this business's growth come with real pricing power and returns on capital (ROIC)?
Is the product differentiated, or will it become a commodity in a price war?
Is its capex "widening the moat," or burning cash because competition forces it to?
Will the trend's dividend land with shareholders, or with consumers and latecomers?
Essence
World-changing industries are often capital-destroying industries — growth itself is never a moat.
This Week's Reflection
Have you ever bought an asset because "this is the future"? Did you compute its return on capital then, or only its growth?
PRINCIPLE 04 · The Commodity View
The Non-Productive AssetCommodities Don't Procreate
The nature of an asset
The Principle
Commodities (gold, oil, metals) create no cash flow of their own — investing in them isn't compounding but a bet that "someone will pay a higher price." It is a fundamentally different game.
Source + Quote
"[Gold] has two significant shortcomings, being neither of much use nor procreative... if you own one ounce of gold for an eternity, you will still own one ounce at its end."
— Warren Buffett, Berkshire 2011 Letter to ShareholdersYou can fondle the cube, but it will not respond.
Deeper Reading
Buffett divides investments into three kinds: currency-denominated assets (cash, bonds), assets that produce nothing (gold, commodities), and productive assets (businesses, farms, real estate). The entire return of the second comes from "someone paying more later" — that is speculation, not investment. An ounce of gold a century later is still that ounce; a farm or a great company keeps producing cash. This doesn't mean commodities should never be held — in inflation or as a crisis hedge they have tactical value, but you must be clear-eyed: you're making money on price, not on compounding, and there is no intrinsic-value anchor to tell you whether it's "dear or cheap."
Classic Case
In the 2011 letter Buffett did the arithmetic: the world's roughly 170,000 tonnes of mined gold would form a cube about 21 meters per side, worth about $9.6 trillion. For the same money you could buy all US cropland (producing about $200 billion a year) plus about 16 ExxonMobils, and still have about $1 trillion left over. A century on, the cropland still grows grain and the oil firms still pay dividends, while the gold cube "produces nothing at all."
Limits + Decision Checklist
Buffett's critique has its limits — Berkshire itself bought the gold miner Barrick Gold in 2020 (then sold it). In specific macro regimes (high inflation, negative real rates) commodities do have a phase-by-phase role, and a pure "productive-asset" framework is not all-powerful.
Am I buying this asset because it produces cash, or because I'm betting the price rises?
With no cash-flow anchor, on what basis do I judge it "dear" or "cheap"?
Is this a core holding (compounding) or a tactical hedge (timing)? Have I kept them straight?
Essence
Productive assets make time your friend; in non-productive commodities, time takes no one's side.
This Week's Reflection
What share of your portfolio is bet on assets that "produce nothing and only pay off if the price rises"? Is that share a considered tactical allocation, or unwitting speculation?
Going Deeper
Since cyclicals' valuation signal is inverted (a low P/E is dangerous), what should an ordinary investor actually use to gauge cycle position?
Using P/E almost guarantees getting it backwards. A more reliable anchor is the commodity price relative to long-run marginal cost of production: when the market price falls below the cash cost of most capacity, losses force supply offline — a bottom signal; when price runs far above cost and everyone expands — a top signal. Add the trend in industry capex, and "normalized earnings" (estimating earning power on a mid-cycle price rather than the current one). The core is to always take a "through-the-cycle" view, not a snapshot of this single year.
The capital-cycle framework demands going against the crowd and years of patience — why, knowing it works, can most people not do it?
Because it collides directly with human nature and career incentives. Buying against the cycle means buying when the industry is most dismal and the news most bleak, and possibly suffering for years before returns appear — psychological torture for individuals, career risk for fund managers (underperform too long and you're redeemed and fired). Those without long enough capital get washed out before dawn. That's exactly why the capital cycle's excess returns persist: it's a "patience premium," structurally hard to arbitrage away.
The energy transition is a certain long-term trend yet may be a poor investment — is AI the same story replaying? How to tell "trend" from "good business"?
Structurally they're highly similar: both are genuinely world-changing trends, both attract vast capital, both face the question of "who gets the dividend." The key to telling trend from good business is to ask which link in the chain has pricing power and returns on capital. Solar's money was eaten by consumers and price wars; with AI you must ask the same — is it the model layer (possibly commoditized, cash-burning), the application layer, or the "sell the shovels" compute and equipment layer that holds the barriers? Buffett's airline/auto lesson reminds us: fast growth, capital intensity, and commoditized competition are the classic recipe for destroying shareholder value.
Buffett dismisses commodities as "non-productive assets"; but in an era of relentless fiat debasement and geopolitical turmoil, does the framework itself have a blind spot?
Possibly. Buffett's framework is near-airtight in a world of "stable currency and freely operating businesses," but it implicitly trusts fiat and institutions. In hyperinflation or monetary-system upheaval, "non-productive" gold becomes a store of value precisely because it depends on no one's promise to pay — its role for millennia. A safer stance may be to treat commodities as a small-percentage insurance (hedging tail risk) rather than a core compounding engine — honoring Buffett's insight without being bound by it.
