The Central Macro Tension
Our starting point is straightforward: the equity market can remain structurally supported even while the macro backdrop becomes considerably less forgiving. That apparent contradiction is the defining investment problem of late 2026. The bullish case does not require low interest rates, an easy Federal Reserve, or endlessly accelerating earnings. It requires something more subtle: productivity gains, capital expenditure, operating leverage, and corporate profitability strong enough to offset a materially higher discount rate.
That distinction matters because the economy is no longer behaving like a conventional late-cycle expansion. Real U.S. GDP grew at a 1.5% annualized rate in the second quarter of 2026, down from 2.1% in the first quarter, yet real final sales to private domestic purchasers increased 4.2%. At the same time, corporate profits from current production rose by $400.9 billion in the second quarter, following a $74.4 billion increase in the first quarter. The combination suggests that headline GDP alone is not capturing the entire strength of private-sector demand and corporate profitability. r1
I therefore view the current environment as a contest between two compounding forces. The first is a productivity and earnings mechanism capable of pushing equity valuations higher even without falling yields. The second is a rate and liquidity mechanism capable of compressing valuations if real yields, term premiums, or funding costs continue rising. The question is not simply whether stocks are expensive or cheap. The more important question is whether the growth in the denominator of valuation can keep pace with the increase in the discount rate.
The “Coiled Spring” Thesis and What It Really Means
The coiled-spring concept is best understood as a volatility-and-positioning thesis rather than a simple prediction of an imminent rally. A market can become compressed when investors disagree about the future while remaining heavily concentrated in a relatively narrow set of exposures. In that configuration, relatively small changes in macro data can generate disproportionately large changes in positioning, volatility, and valuation.
There are two possible releases of that spring. One is upward: economic data remain resilient, earnings expectations rise, liquidity improves, and investors discover that their portfolios are underexposed to productive risk. The other is downward: inflation proves persistent, long-duration yields rise further, earnings expectations fail to justify elevated multiples, and concentrated technology exposure becomes a source of forced de-risking.
My interpretation is that the asymmetry comes from the interaction between earnings duration and interest-rate duration. High-growth equities possess substantial economic duration because a large proportion of their valuation depends on cash flows far into the future. When long-term yields rise sharply, that duration becomes a liability. But if productivity growth simultaneously raises expected future cash flows, the same duration becomes an asset. This is why the equity market can absorb higher rates for a surprisingly long period if the earnings engine remains powerful.
Recent earnings evidence provides some support for the latter mechanism. FactSet reported in early September that analysts had increased aggregate third-quarter bottom-up S&P 500 earnings estimates by 1.2% from June 30 through August 31, reaching $89.69 per share. That is notable because analysts typically cut estimates during the first two months of a quarter; over the prior five and ten years, the average declines were 1.7% and 2.1%, respectively. r2
That does not establish that equities must rise. It establishes something more useful: the earnings revision cycle had, at least through August, been behaving better than normal despite concerns about input costs and energy. For valuation, the direction of earnings revisions can be more informative than the absolute level of earnings because markets discount changes in expectations rather than merely current accounting outcomes.
Productivity Is the Crucial Variable
The productivity thesis deserves considerably more attention than the simplistic debate over whether artificial intelligence is a bubble. The relevant economic question is not whether artificial intelligence companies are richly valued. The relevant question is whether technology investment is beginning to raise economy-wide output per unit of labor and capital.
If productivity rises materially, several macro relationships change simultaneously. Companies can produce more output without proportionately increasing labor costs. Unit labor costs can stabilize even when wages rise. Operating margins can expand. Higher margins can support stronger earnings. Stronger earnings can justify higher equity multiples. That creates a reinforcing loop between investment and valuation.
But this mechanism has a timing problem. Capital expenditure arrives before productivity benefits are fully realized. Investors therefore finance an uncertain future using present cash flows and present credit markets. During the buildout phase, capital intensity can increase depreciation, financing requirements, energy consumption, infrastructure demand, and leverage. If the eventual productivity gains fail to meet expectations, the market can discover that it financed too much capacity too quickly.
This is the classic mechanism through which technological investment cycles can become financial cycles. The technology does not have to be fraudulent for the valuation to become excessive. Genuine technological progress can coexist with excessive capital allocation. That distinction is critical for portfolio construction.
The Bond Market Is Becoming the More Important Variable
The most consequential development for risk assets is the level of long-term Treasury yields. As of September 23, the Federal Reserve's daily H.15 data showed the 10-year Treasury yield at 5.11%, the 20-year at 5.45%, and the 30-year at 5.40%. The corresponding 10-year inflation-indexed yield was 2.76%. r3
Those numbers fundamentally change the opportunity set. A 5%-plus nominal Treasury yield is not merely a higher hurdle for equities. It changes the opportunity cost of holding virtually every risk asset. Investors can obtain substantial nominal income without accepting corporate default risk, equity-duration risk, or cryptocurrency volatility. Consequently, risk assets must provide a compelling combination of earnings growth, cash-flow durability, and valuation support to attract marginal capital.
The real-yield component is particularly important. A 10-year real yield around 2.76% represents a substantial real return requirement embedded in the global pricing system. If real yields remain elevated, the equity market cannot depend on multiple expansion alone. Earnings growth must do more of the work.
This is where the bullish equity thesis becomes more demanding. A market can tolerate higher nominal yields if those yields are accompanied by stronger nominal growth and stronger corporate cash flows. But if yields rise because inflation expectations and real term premiums are increasing while earnings expectations remain unchanged, the valuation arithmetic becomes considerably less favorable.
The Federal Reserve Has Changed the Rate Regime
The September 2026 Federal Open Market Committee meeting is an important marker because monetary policy is no longer operating in the same direction as it did during the earlier easing phase of the cycle. The Federal Reserve's official September 15–16 meeting materials confirm that the committee met during a period in which the policy framework and projections were being reassessed. r4
The market consequence is more important than the precise policy-rate level: investors must now account for the possibility that long-term yields can remain elevated even if short-term monetary policy eventually becomes less restrictive. That happens because long-duration yields are determined by more than the expected path of the federal funds rate. They also incorporate expected inflation, real growth, fiscal borrowing requirements, term premium, global capital flows, and the supply-demand balance for government debt.
That creates a particularly difficult environment for the traditional assumption that a future easing cycle automatically produces a major bond rally and therefore a synchronized equity rally. The two outcomes can diverge. Short rates can decline while the long end remains stubbornly elevated if investors demand greater compensation for inflation, fiscal risk, or duration exposure.
Our analysis therefore treats the 10-year yield as a macro regime variable rather than simply another market price. If long yields stabilize near current levels while earnings continue to rise, equities can potentially digest the rate shock. If yields continue climbing rapidly, however, the market's valuation structure becomes increasingly vulnerable.
Why 2027 Earnings Matter More Than 2026 Headlines
The market's next major test is the transition from unusually strong current earnings growth toward the more difficult comparison base of 2027. This is where the concept of operating leverage becomes decisive.
Suppose revenues continue growing, but at a slower rate. If productivity allows companies to control labor and input costs, margins can continue expanding despite slower top-line growth. Earnings can therefore remain surprisingly strong even when GDP growth moderates. This is the mechanism behind the productivity-boom thesis.
But the reverse is also true. If revenue growth slows while wages, energy, financing costs, and depreciation remain elevated, margins can contract quickly. Because equity valuations capitalize earnings, a simultaneous decline in earnings estimates and valuation multiples can create a much larger drawdown than either factor alone would imply.
That is why I would focus less on whether earnings growth is slowing and more on the composition of that slowdown. Slower earnings generated by falling margins are materially different from slower earnings generated by an already-anticipated normalization in revenue growth while margins remain structurally elevated.
| Macro condition | Corporate earnings effect | Equity valuation implication | Primary risk |
|---|---|---|---|
| Strong productivity, stable yields | Margin expansion and resilient EPS | Multiples can remain supported | Expectations become too optimistic |
| Strong productivity, rising yields | EPS growth offsets some discount-rate pressure | Selective valuation support | Long-duration equities remain vulnerable |
| Weak productivity, stable yields | Margin expansion fades | Multiples require earnings support | Earnings revisions turn negative |
| Weak productivity, rising yields | Margins and EPS face pressure | Multiple compression becomes more likely | Simultaneous earnings and valuation shock |
Liquidity Is Not the Same Thing as Easy Money
A critical analytical distinction is the difference between liquidity and monetary accommodation. Liquidity can improve for reasons that do not necessarily imply a structurally easier central bank. Treasury cash management, bank reserve dynamics, financial regulation, market plumbing, asset purchases, and private credit creation can all influence the amount and distribution of liquidity in financial markets.
For equities, this distinction matters because liquidity can support valuation even when policy rates remain comparatively restrictive. But liquidity cannot permanently override the arithmetic of real yields. If the risk-free rate rises sufficiently, investors eventually demand more earnings yield from equities, more spread from corporate credit, and more compensation for speculative assets.
This creates an important hierarchy. At modest changes in liquidity, positioning and sentiment can dominate. At extreme changes in discount rates, fundamental valuation tends to reassert itself. Our framework therefore treats liquidity as a catalyst rather than as an independent guarantee of higher asset prices.
The Portfolio Architecture Behind the Macro Regime
The appropriate portfolio response to this environment is less about making a single directional call and more about understanding what each asset is designed to hedge. Equities represent productive capacity and corporate claims on future cash flows. High-quality government bonds provide nominal income and, under the right recessionary conditions, duration protection. Gold provides exposure to real assets and monetary confidence. Bitcoin and other cryptocurrencies represent a distinct form of monetary and technological optionality, but with substantially higher volatility and liquidity risk.
The important point is that these assets should not be treated as interchangeable versions of “risk on.” Their economic functions are different. A portfolio constructed around those functions can remain robust even when the macro regime changes, whereas a portfolio built around correlations observed during a single period can fail when those correlations reverse.
The same principle applies within equities. Exposure to productivity beneficiaries is not identical to exposure to high-duration growth stocks. A company can benefit from technological investment while still suffering from valuation compression if its multiple becomes excessively sensitive to the long bond. The quality of the underlying business and the duration of its valuation are separate analytical variables.
Bitcoin, Gold and the Monetary Regime
Gold and cryptocurrency should also be analyzed through different monetary channels. Gold has historically functioned as a non-sovereign store of value and as a hedge against monetary and financial-system uncertainty. Bitcoin carries a different proposition: its value is much more dependent on adoption, liquidity, risk appetite, technological infrastructure, and perceptions of monetary scarcity.
That distinction becomes particularly important when real yields are rising. Higher real yields increase the opportunity cost of holding assets that do not generate conventional cash income. Gold can still benefit from concerns over currency credibility or systemic risk, but its performance becomes more sensitive to the balance between those concerns and the return available from real assets and government securities.
Bitcoin faces an even more complex interaction because it behaves simultaneously as a speculative growth asset and as a monetary alternative. During periods of abundant liquidity, those characteristics can reinforce one another. During periods of tightening financial conditions, they can conflict. Treating cryptocurrency as a simple substitute for gold therefore obscures an important source of portfolio risk.
The Secular-Bear Risk Cannot Be Ignored
A powerful productivity cycle can ultimately sow the conditions for its own reversal. Strong returns encourage capital formation. Capital formation encourages competition. Competition compresses returns on invested capital. Easy financing can sustain marginal projects longer than fundamentals justify. Eventually, excess capacity and excessive leverage collide with slower demand.
This is why a genuine technology revolution can still culminate in a severe equity bear market. The secular risk does not necessarily come from technology failing. It can come from investors extrapolating technological success too aggressively into asset prices and corporate capacity.
The historical lesson is not that technological booms should be avoided. It is that the investment cycle must be separated from the valuation cycle. A technology can transform the economy while the securities associated with that technology experience enormous fluctuations in fair value.
What Would Confirm or Break the Bullish Case
I would monitor five variables above everything else: earnings revisions, operating margins, long-term real yields, capital-expenditure productivity, and credit conditions. These variables connect the real economy to the valuation mechanism.
The bullish configuration would be evidence that earnings estimates continue rising, productivity gains are becoming visible in margins, investment is producing measurable output gains, and long-term yields stabilize rather than accelerate upward. Under that combination, equities could potentially absorb a high-rate environment because fundamental earnings power would be compensating investors for the higher discount rate.
The bearish configuration would be different: long-term real yields continue rising, earnings revisions turn negative, margins peak, credit spreads widen, and capital expenditure continues increasing despite deteriorating returns. That combination would suggest that the economy is moving from productive investment toward overcapacity and financial stress.
There is also a middle regime that investors often underestimate. Earnings can remain strong while valuations compress. In that environment, index-level returns can become much more dependent on actual earnings growth rather than multiple expansion. The market may remain fundamentally healthy while producing substantially more dispersion between companies, sectors, and investment styles.

|---|---|---|---|
| Real GDP | Q2 growth of 1.5% | Moderate headline growth | Q3 acceleration or further deceleration |
| Private domestic demand | Real final sales up 4.2% | Underlying private demand remains stronger than headline GDP | Consumer resilience and investment |
| Corporate profits | $4.83 trillion annualized in Q2 | Profit base remains powerful | Margin sustainability |
| S&P 500 EPS revisions | Q3 estimate rose 1.2% through August | Revision momentum was unusually constructive | Whether revisions remain positive into Q4 |
| 10-year Treasury | 5.11% on September 23 | High discount-rate environment | Real yield and term-premium trajectory |
| 10-year real yield | 2.76% on September 23 | High hurdle for risk assets | Whether real yields stabilize or climb further |
| Capital expenditure | Structurally elevated around technology investment | Potential productivity catalyst and eventual overcapacity risk | Return on incremental investment |
The Investment Conclusion
My conclusion is that the equity market can remain structurally resilient, but the nature of the resilience has changed. The easy version of the bull market would be falling rates, expanding liquidity, rising earnings, and multiple expansion simultaneously. That is not the environment investors can safely assume in late 2026.
The more demanding version of the bull market is a productivity-led expansion in which corporate earnings grow rapidly enough to compensate for a structurally higher risk-free rate. That scenario is plausible, and current corporate-profit and earnings-revision data provide meaningful evidence that the underlying earnings engine remains strong. But it requires continuous confirmation rather than passive extrapolation. r5
The bond market is therefore the critical referee. With the 10-year Treasury around 5.1% and the 10-year real yield near 2.8%, the market is assigning substantial value to safe nominal and real income. r6 Equity investors can still win that competition, but they need earnings, productivity, and cash-flow growth to justify the premium.
That is the essence of the coiled-spring framework. The spring is not simply a promise of an upward breakout. It is compressed potential energy created by conflicting macro forces: resilient private demand against slower headline GDP, exceptional corporate profitability against higher financing costs, technological investment against valuation risk, and strong liquidity possibilities against a historically demanding real-rate environment.
Our strategic implication is consequently neither complacency nor indiscriminate defensiveness. The highest-value analytical task is identifying whether productivity is becoming sufficiently powerful to overwhelm the discount-rate shock. If it is, the equity cycle can extend substantially further even without a return to ultra-low interest rates. If it is not, the same concentration and duration characteristics that amplified the upside can amplify the eventual correction.
The next decisive data are already close. On September 30, the Bureau of Economic Analysis is scheduled to release the third estimate of second-quarter GDP and corporate profits, alongside August personal income and outlays data. The third-quarter GDP advance estimate follows on October 29. r7 Those releases will help determine whether the apparent productivity-and-profitability regime is broadening or whether the market is relying increasingly on a narrower set of corporate outcomes.
In other words, I would not frame the current investment question as whether equities are “safe” or whether bonds are “dead.” Both statements are too simplistic. The real question is which side of the growth-versus-discount-rate equation is changing faster. As long as productivity and earnings growth remain capable of outrunning the pressure from real yields, the equity structure can remain remarkably durable. If the rate structure accelerates while earnings momentum deteriorates, the same market can become remarkably fragile. That is the macro fault line investors should monitor.
