Earnings Drive Stocks, Rates Make Noise

The short-term noise and handwringing about this week’s Federal Reserve (Fed) interest rate hike and rising bond yields (regression coefficient = -0.21) focuses on less important, albeit negative, determinants of stock prices. For long-term investors, the most important driver of share prices is earnings (regression coefficient = 0.96).

Fortunately, the US large company earnings “boom” is literally in uncharted territory! Indeed, S&P 500 trailing 12-month (TTM) operating earnings per share (EPS) soared 35% year-over-year (Y/Y) in 2Q26, a pace we’ve never enjoyed in the absence of a recession/recovery, low base, easy comparison and denominator effect.

Four Horsemen” of the Earnings “Boom

While forecasting exact trajectories in this unique environment is incredibly difficult, we can attempt to “triangulate” a possible outcome by blending macroeconomic momentum and microeconomic estimates with stylized “cycle-on-cycle” analysis.

Probing for PeakEarnings Growth, not “Peak” Earnings

Sources: FactSet, FRED, S&P Global, WCG, 09/15/26. Notes: Vertical gray bands = US economic recessions. SD = Standard deviation. TTM = Trailing 12 month. EPS = Earnings per share. MMI = A composite of SK exports, the ISM Manufacturing Index, copper and global industrial materials prices. E = Estimate.

Having assessed about a dozen coincident to leading economic indicators, I created a new Macro Momentum Indicator (MMI) which has led S&P 500 TTM operating EPS growth by roughly six months. Using a z-score transformation, I “normalized” and combined the “first four movers,” which include South Korean (SK) export growth and the Institute for Supply Management (ISM) Manufacturing Index – planetary measures of technology and industrial demand – as well as copper and global industrial materials price changes – physical supply chain barometers (see the chart above).

Long-Term Signal Versus Short-Term Noise

My top-down MMI suggests a better-than-expected “peak” earnings growth rate of approximately 40%+ Y/Y (or $377) compared to the bottom-up analyst consensus estimate of 36% Y/Y (or $364):

  • Harmonic Convergence: Coincidentally, ~40% Y/Y happens to be the average “peak” earnings growth rate across all business cycles, blending the extremes of both recessions/recoveries and expansions since 1990.
  • Upside Risks: However, nothing about the current business cycle has been “average.” Despite intermittent shocks, surprisingly resilient nominal economic growth (6.6% Y/Y), stellar sales growth (15.6% Y/Y) and record margin expansion (17.0%) probably skew earnings risks to the upside, depending mostly on operating leverage, cost discipline and management execution.

Mosaic Theory

Based on currently available information, my basket of global leading indicators points to “maximum” earnings growth arriving in 4Q26. Coincidentally, bottom-up analysts also expect the earnings impulse to crest in the same quarter, meaning top-down macro and bottom-up micro models agree on the timeline.

For now, however, the four cylinders of the earnings engine are running hot:

SK Export Growth (69%) Is Ludicrous but Looking “Toppy

Sources: FactSet, FRED, S&P Global, WCG, 09/15/26. Notes: MOTIE = Ministry of Trade, Industry and Energy.

SK Export Growth – Ludicrous Speed

Importance: South Korea is a key bellwether for global trade, heavy industry, automotive production and technology / semiconductor supply chains. It’s also one of the first significant releases on the economic calendar each month, which allows us to assess world-wide demand ahead of month-end reports.

Signal: Monthly SK export growth, which “eased” to a ludicrous pace of 69% Y/Y in August from a recent top speed of 71% Y/Y in June, provides a 2-month lead on S&P 500 earnings growth with a strong positive correlation coefficient of 0.66. Global trade momentum confirms astonishing tech and industrial strength, which is unlikely to persist indefinitely (see the chart above).

ISM Manufacturing Index – Plenty of Gas in the Tank

Importance: The ISM is a composite index based on a monthly survey of purchasing and supply executives from over 400 manufacturing companies across the US. This widely followed report is also available on the first business day of each month.

Signal: The monthly ISM Manufacturing Index, which down ticked to a robust 54.6% in August from a nearby high of 55.6% in July, has a 4-month lead on S&P 500 earnings growth with a strong positive correlation coefficient of 0.68. Factory gate demand reflects a robust pipeline of activity (see the chart below).

Historically, the ISM (55%) Has Crested in the High 50s to Low 60s

Sources: FactSet, FRED, S&P Global, WCG, 09/15/26.

Copper – Canary in a Chilean Mine

Importance:Dr. Copper” is another early warning sign for global industrial production, construction, capital expenditures (capex) and supply chain activity. When real-time copper price changes begin to roll over, US large-cap earnings growth usually slows with a lag.

Signal: Copper price increases, which decelerated to 31% in September from a recent high of 46% in July, have a 5-month lead on S&P 500 earnings growth with a strong positive correlation coefficient of 0.64. Despite weather-related disruption, steady physical infrastructure and capex growth support the structural economic base beneath earnings and the stock market (see the chart below).

Global Industrial Materials – No Signs of Distress

Importance: The International Monetary Fund (IMF) Global Industrial Materials Price Index is a benchmark measure of raw manufacturing inputs, excluding energy and fuels. It focuses strictly on the primary industrial components of base metals (copper, aluminum, iron ore, tin, nickel, zinc, lead and uranium) and raw agricultural materials (timber, wool, cotton, hides and natural rubber).

Signal: Global industrial materials price gains, which cooled to 20% in July from a nearby high of 28% in May, sit at the top of the production line and have a 4-month lead on S&P 500 earnings growth with the strongest positive correlation coefficient of 0.74. Despite recent cooling, global raw input prices confirm a healthy underlying industrial pulse (see the chart below).

Copper Price Gains (31%) Are Elevated but Not Extreme

Sources: FactSet, FRED, S&P Global, WCG, 09/15/26. Notes: LME = London Metals Exchange. COMEX = Commodity Exchange.

Beyond a potential 4Q26 “peak,” my stylized “cycle-on-cycle” analysis suggests earnings may decelerate a bit more sharply than consensus anticipates, downshifting to a slightly worse-than-expected pace of 13% Y/Y (or $398) in 3Q27 compared to the bottom-up analyst estimate of 15% Y/Y (or $399).

Global Industrial Materials Price Increases (20%) Are Similarly Elevated but Not Extreme

Sources:FactSet, FRED, S&P Global, WCG, 09/15/26. Notes:IMF = International Monetary Fund.

Earnings Engine – Downshifting, Not Stalling

To be clear, this isn’t a bearish change of view. Rather, it simply means that corporate profits should keep rising at a slower pace. The bottom line is that my projected 2027 “normalization” is largely a function of higher base effects and increasingly difficult comparisons next year.

Technology Angst

I barely remember, but our family once had a game called Pong1. The premise was super simple – hit the ball with the digital paddle as if in a game of ping pong. The graphics were practically nonexistent. The game objective was clear. Fast forward to Space Invaders and then to Nintendo and Super Mario Bros., then to PlayStation and Xbox, and the games got more engaging, had much better graphics, became more complex, and became more addictive.

Screenshot of Pong

We saw an evolution with cell phones and tablets. We saw massive numbers of users also join in social networks – Facebook, YouTube, Twitter, and Instagram. We witnessed some problems get solved – finding a friend across the world on Facebook after more than 30 years – and other problems get created – phone addiction, mental health struggles, decreased social interaction, etc. We still find solutions and we still find ourselves with additional challenges.

ChatGPT 3.5 came out on November 30, 2022, and it felt revolutionary2. Looking back not quite four years later, the entire world has changed as a result of artificial intelligence (AI). We are now on ChatGPT-6 and there are many other models, both frontier and open free models3.

Some of the largest companies by market value are now either directly or indirectly related to AI hardware, AI software models, or data centers4. Trillions of dollars will likely be spent on software, hardware, infrastructure, and energy generation related to AI5.

The models have gotten much better, but also more complex. Many problems have been solved and new ones have emerged. This pattern is true for AI as it has been for other technologies6.

With all this change has come increased anxiety about job security, privacy, national security, and what the future will look like. It’s been a mixture of excitement about possibilities – the potential to cure diseases and solve complex problems, autonomous vehicles, brain implants that will allow the paralyzed to walk again, helper robots – but also much anxiety and angst.

The angst seemed to come to a new head in the last week. Several leaders of AI companies publicly stated that we need to slow the pace of AI development and deployment7. An  Anthropic researcher reportedly estimated that there was a greater than 10% chance that AI could see humans go extinct within the next decade8. At the same time, other leaders in government and at AI hardware companies said there’s no reason to slow things down7,9.

There’s complexity to the issue and risks are not one-sided:

  • Increased supervision and regulation could protect society, but it could also protect the profits of the leading frontier companies and stifle competition.
  • A slowdown could allow the Chinese-backed AI models to catch up and be on a level playing field with the US models.
  • A slowdown in innovation and development may encourage engineers to leave the US and move to where there is no measured pacing.
  • Not slowing the development and deployment could mean loss of control of AI agents and models that find ways around rules.
  • Not slowing down could introduce newer cyber threats that consumers, businesses, and local, state, and federal governments are not prepared to handle.
  • Not slowing the pace might mean that we run out of energy capacity to support the innovative growth.

These are all possibilities. Nothing is certain. There’s no easy answer. And that’s okay. Our country is endowed with a number of extremely talented individuals from all walks of life. Some are in government. Some in business. Some are engineers. Others are in finance or economics. Others in math. Many are working in technology to solve problems we may not even know about. As we have always done, we will work the problem or problems and try to come up with solutions. We will likely make mistakes along the way, but we will most likely figure it all out. It will take time. We have figured it out before and we will likely do the same here again. We found a way to go to the Moon when it seemed impossible. We found ways to inoculate ourselves from harmful diseases. We found a way to make cars drive themselves. We found a way to make computers model things and reason and help solve problems. We figured out how to get qubits to behave a certain way and advance quantum computing.

I am confident that we will use some of these new tools to also figure out the best ways to reduce the risks or protect against them. That may mean hardening cybersecurity and building more rules for models or model agents. Or it may mean coming out with better and safer designs that enhance both innovation and safety and privacy and national security.

As someone who uses some of the most advanced AI models on a regular basis, I am confident that we will work through many of these challenges and develop better solutions. It won’t happen overnight and it may be messy, but I believe we will figure it out.
