The S&P 500 (Index: SPX) closed out the first week of December 2025 at 6,870.40, up 0.3% from where it closed the previous week.

The main focus of investors continues to be what action the Federal Reserve will take with short term U.S. interest rates. After putting on a show in recent weeks to try to convince markets that it might not continue reducing the Federal Funds Rate at the end of its next rate-setting meeting on Wednesday, 10 December 2025, evidence of continued anemic growth in the U.S. labor market announced during the past week is leading investors to expect the Fed will cut rates.

The CME Group's FedWatch Tool captures that sentiment. It held steady in the past week, indicating an 87% probability of a quarter point rate cut on 10 December (2025-Q4). Looking beyond the end of 2025, the FedWatch tool gives better than even odds for additional quarter point rate cuts on 29 April (2026-Q2) and 29 July (2026-Q3). A third rate cut anticipated for 9 December (2026-Q4) a week ago is no longer in the outlook, with the next potential rate cut pushed out into 2027.

Even though the probability of a rate cut is high, the Fed's minions arguing against a rate cut have succeeded in creating enough doubt that investors remain focused on the current quarter of 2025-Q4 in setting current day stock prices. The latest update of the alternative futures chart shows the trajectory of the S&P 500 falls in the middle of the redzone forecast range we added two weeks earlier, assuming investors would be focused on 2025-Q4 going into this upcoming trading week.

Alternative Futures - S&P 500 - 2025Q4 - Standard Model (m=-2.0 from 28 Apr 2025) - Snapshot on 5 Dec 2025

After the Fed meets, there will be little reason for investors to continue placing much attention on 2025-Q4. We think investors will quickly shift their forward-looking attention toward the slightly more distant quarter of 2026-Q1, since it will become the focus of timing for the next rate change actions by the Fed.

Whether that plays out as we think will depend on the random onset of new information. Speaking of which, here are the market-moving headlines that influenced investor expectations during the past week.

Monday, 1 December 2025

Friday, 5 December 2025

We're rapidly coming up on another period in which we'll need to add another redzone forecast range to the chart to track the most likely trajectory the S&P 500 will be taking in the weeks ahead. Unlike the current redzone forecast range that is set to end early in this upcoming week, we anticipate the actual trajectory of the S&P 500 will overshoot the projections of the dividend futures-based model for several weeks going into 2026. This is a consequence of the model's use of historic stock prices as the base reference points for making its projections of the S&P 500's future, in which the echoes of past volatility affect the model's forecasts. The redzone forecasts we add get around that inconvenience by bridging across the period in which those echoes affect the model's raw projections.

The Atlanta Fed's GDPNow tool projection of real GDP growth in the U.S. during the recently ended 2025-Q3 ticked down from +3.9% last week to +3.5% week. The tool won't shift to forecast 2025-Q4's GDP until 23 December 2025. The BEA's official initial estimate of GDP for 2025-Q3 will be released on that date.

Multicolored soap bubble image by Alexa from Pixabay - https://pixabay.com/photos/soap-bubble-multicoloured-bullet-824927/

A little over three years ago, Artificial Intelligence (AI) technology took off in the public consciousness with OpenAI's public release of ChatGPT.

That event took place in a period of relative chaos for the U.S. stock market. That period of chaos started with the S&P 500's plunge after February 2020 with the arrival of 2020's coronavirus pandemic in the U.S., which ended the period of relative order that had established itself in December 2018. The inflation phase of the bubble began after March 2020 with the passage of COVID stimulus funds, which initiated the inflation of the COVID/Biden Stimulus Bubble.

The deflation phase of that bubble began after it peaked in December 2021 and by June 2022, the level of the S&P 500 had returned to levels consistent with where stock prices would have been had the relative order that had been in place starting in December 2018 had simply continued. The following chart, which tracks the average monthly value of the S&P 500 against its underlying trailing year dividends per share shows the scale of that event in the context of the relative periods of order and chaos we've documented since December 1991.

S&P 500 Average Monthly Index Value vs Trailing Year Dividends per Share, Logarithmic Scale, December 1991-June 2022 (through 22 June 2022)

Stock prices continued falling through September 2022 before starting to re-establish some semblance of relative order in the latter part of that year when stock prices began to recover. ChatGPT was rolled out in that environment on 30 November 2022, which helped contribute to the stock market's initial recovery phase that ran through late July 2023, then reversed through late October 2023. It wasn't until 29 December 2023 that what we define as the current period of relative order established itself.

From here, we can track the progress of the current period of relative order in the U.S. stock market on a more refined chart. Here is what that period of order looks like from 29 December 2023 through 2 December 2025:

S&P 500 Index Value vs Trailing Year Dividends per Share, 29 December 2023 through 2 December 2025

This chart allows us to quantify what most analysts might identify as the AI bubble, but which we do not because of how we define what a bubble is. Here is our working definition:

An economic bubble exists whenever the price of an asset that may be freely exchanged in a well-established market first soars then plummets over a sustained period of time at rates that are decoupled from the rate of growth of the income that might be realized from owning or holding the asset.

Going back to our chart of the current period of relative order, we find it captures the inflation and deflation phase of the so-called "AI Bubble" that has occurred within it. The inflation phase runs from 29 December 2023 and continues until it peaks in 19 February 2025, just ahead of a market-shaking event for AI stocks. That event came in the form of China's Hangzhou DeepSeek Artificial Intelligence Basic Technology Research company's Friday, 21 February 2025 statement that they would release an open source version of their advanced AI system in the following week, which they followed through and did on Monday, 24 February 2025.

This event popped the proverbial AI bubble. Stock prices plunged until they started to stabilize in late March 2025, but by then, what passed for the AI bubble had all but fully deflated.

Shortly afterward, President Trump's 2 April 2025 "Liberation Day" global tariff announcement sent the S&P 500 plunging much lower, threatening to break the market's current relative period of order. It didn't because less than a week later, President Trump announced a 90-day suspension of the higher tariffs would seek to impose, which prompted a rapid recovery in stock prices that prevented order from fully breaking down.

However, it's not until late June 2025, after Nvidia (NYSE: NVDA) announced blockbuster earnings of its AI-chip systems that we see signs the AI-bubble may have begun a new inflation phase.

From our perspective, the so-called AI bubble doesn't yet deserve that designation. Although it has contributed to making the current relative period of order somewhat chaotic, stock prices remain within the range we identify has established itself during this period, for which we can used the tools of statistical analysis to quantify. The first inflation-deflation phase of the AI-bubble would at best cover 2.5 standard deviations of the variation of stock prices recorded between 29 December 2023 and 2 December 2025, or about 612 points. What passes as its new inflation phase, which we track from 20 June 2025 to the present, is similar in magnitude and is equivalent to about 9% of the current value of the S&P 500.

What would it take for us to officially recognize the AI Bubble as an actual bubble? We would need to see the 20-day moving average of the S&P 500 rise above the upper red dashed line indicated on our refined chart and stay there. For the upcoming milestone of the S&P 500's trailing year dividends reaching $79 per share, that would mean the index sustaining a level above $7,000 for at least 20 trading days to even begin to qualify. Which is to say the earliest that might happen would be early in 2026.

Celebrating Political Calculations' Anniversary

We hope you've enjoyed this analysis because we're celebrating our anniversary a little early this year! Our anniversary posts typically represent the biggest ideas and celebration of the original work we develop here each year, where we've only missed 2024 because we were tied up with other projects. Here are our landmark posts from previous years:

  • A Year's Worth of Tools (2005) - we celebrated our first anniversary by listing all the tools we created in our first year. There were just 48 back then. Today, there are over 300....
  • The S&P 500 At Your Fingertips (2006) - the most popular tool we've ever created, allowing users to calculate the rate of return for investments in the S&P 500, both with and without the effects of inflation, and with and without the reinvestment of dividends, between any two months since January 1871.
  • The Sun, In the Center (2007) - we identify the primary driver of stock prices and describe a whole new way to visualize where they're going (especially in periods of order!)
  • Acceleration, Amplification and Shifting Time (2008) - we apply elements of chaos theory to describe and predict how stock prices will change, even in periods of disorder.
  • The Trigger Point for Taxes (2009) - we work out both when, and by how much, U.S. politicians are likely to change the top U.S. income tax rate. Sadly, events in recent years have proven us right.
  • The Zero Deficit Line (2010) - a whole new way to find out how much federal government spending Americans can really afford and how much Americans cannot really afford!
  • Can Increasing the Minimum Wage Boost GDP? (2011) - using data for teens and young adults spanning 1994 and 2010, not only do we demonstrate that increasing the minimum wage fails to increase GDP, we demonstrate that it reduces employment and increases income inequality as well!
  • The Discovery of the Unseen (2012) - we go where so-called experts on income inequality fear to tread and reveal that U.S. household income inequality has increased over time mostly because more Americans live alone!

We marked our 2013 anniversary in three parts, since we were telling a story too big to be told in a single blog post! Here they are:

  • The Major Trends in U.S. Income Inequality Since 1947 (2013, Part 1) - we revisit the U.S. Census Bureau's income inequality data for American individuals, families and households to see what it really tells us.
  • The Widows Peak (2013, Part 2) - we identify when the dramatic increase in the number of Americans living alone really occurred and identify which Americans found themselves in that situation.
  • The Men Who Weren't There (2013, Part 3) - our final anniversary post installment explores the lasting impact of the men who died in the service of their country in World War 2 and the hole in society that they left behind, which was felt decades later as the dramatic increase in income inequality for U.S. families and households.

Resuming our list of anniversary posts....

On Thanksgiving holiday week, the S&P 500 (Index: SPX) rose 1.7% from its previous week's close, reaching 6,849.09 by the close of trading on Friday, 28 November 2025.

The index' gains was largely driven by growing expectations the U.S. Federal Reserve will act to cut the Federal Funds Rate when its Federal Open Market Committee concludes a two-day meeting on Tuesday, 10 December 2025, overcoming the opposition of the FOMC's biggest grumps who lost face during the year by predicting much higher inflation would result from tariffs than is supported by real world evidence. Through Friday, 28 November 2025, the CME Group's FedWatch Tool indicates an 87% probability of a quarter point rate cut on 10 December (2025-Q4), up from 71% a week earlier and from 44% the week before that.

In 2026, the FedWatch tool gives better than even odds for additional quarter point rate cuts on 29 April (2026-Q2), 29 July (2026-Q3), and 9 December (2026-Q4), which is unchanged from the previous week.

This growing expectation puts the S&P 500's trajectory will within the redzone forecast range we added to the alternative futures chart in the previous edition of the S&P 500 chaos series. Here's the latest update of the chart:

Alternative Futures - S&P 500 - 2025Q4 - Standard Model (m=-2.0 from 28 Apr 2025) - Snapshot on 28 Nov 2025

The other major story that's been driving the direction of the S&P 500 index during 2025 was relatively quiet during the Thanksgiving holiday-shortened trading week. However, what happens with firms making big AI technology-related investments continues to affect the market's direction, which in the past week meant providing the biggest boost to the markets' major indices. Here are the market-moving headlines from the week that was.

It's hard to believe OpenAI's ChatGPT has only been around for three years!

Meanwhile, the Atlanta Fed's GDPNow tool projection of real GDP growth in the U.S. during the recently ended 2025-Q3 decreased from +4.2% to +3.9% as economic data reports resume being reported following the end of the Senate Democrats' government shutdown fiasco. The BEA's official estimates of GDP for 2025-Q3 will likely be delayed into December 2025, which may happen around the time the GDPNow tool gets enough data to finally shift forward to 2025-Q4.

The S&P 500 (Index: SPX) experienced a lot of intraday volatility in the trading week ending on Friday, 21 November 2025. By the close of the week's trading, the index was down 1.95% from its previous week's close.

Two factors combined to put the market through big swings during the week that was. The AI tech stocks that have helped power the S&P 500 to record highs during 2025 got a big boost from Nvidia (NASDAQ: NVDA) after the close of trading on Wednesday, 19 November 2025, when the company announced its cloud GPU products sold out, affirming the megacap's outlook going into 2026.

The market's positive reaction to that news was tempered on Thursday however, as a number of Federal Reserve officials staked out positions against continuing the Fed's recent rate cuts in December 2025. That information sent stock prices down to their lowest level since 10 September 2025, which was partially reversed on Friday when the Fed's second-highest ranking official signaled a rate cut "in the near term" would be likely.

The response by investors to the prospect a "near term" rate cut is remarkable. The CME Group's FedWatch Tool rose to indicate a 71% probability of a quarter point rate cut on 10 December (2025-Q4), up from just 44% a week ago, with virtually all of that change taking place on Friday, 21 November 2025. Meanwhile, the S&P 500 rose nearly one percent on the day to end the trading week at 6,602.99.

Looking further forward, the FedWatch tool gives better than even odds for additional quarter point rate cuts in 2026, coming on 29 April (2026-Q2), 29 July (2026-Q3), and 9 December (2026-Q4). The potential timing of all these projected rate cuts remains very fluid with substantial changes in expectations from week to week.

For the latest update of the alternative futures chart, we've added a new short-term redzone forecast range to compensate for the echo of historic volatility in stock prices in the dividend futures-based model. The echo effect arises as a result of the model's use of historic stock prices as the base reference points from which its projections of future stock prices are determined. The new redzone forecast range assumes investors will remain focused on the current quarter of 2025-Q4 in setting stock prices during the period it runs.

Alternative Futures - S&P 500 - 2025Q4 - Standard Model (m=-2.0 from 28 Apr 2025) - Snapshot on 21 Nov 2025

Speaking of the echo effect, the chart also shows we'll have another, longer period coming up in which the model's projections will be similarly affected, though for that period, we anticipate the model's projections will undershoot the trajectory of stock prices.

We also likely won't know how investors will reset their forward-looking investment time horizon after the Fed's 10 December 2025 meeting. They will shift their attention to a more distant quarter in the future, but the open question that remains to be answered is which one?

Sorting that out depends on the context of the random onset of new information investors will absorb in the weeks ahead. Until those make themselves known, here are the past week's market moving headlines.

Monday, 17 November 2025

The Atlanta Fed's GDPNow tool projection of real GDP growth in the U.S. during the recently ended 2025-Q3 increased from +4.0% to +4.2% as several delayed economic data reports started to come in following the end of the Senate Democrats' shutdown. The BEA's official estimates of GDP for 2025-Q3 will likely be delayed into December 2025 given the upcoming holiday calendar.

With the upcoming Thanksgiving holiday, we're anticipating a low volume of news coming out of the U.S. in the week ahead. That means much of the market-moving news will be coming from outside the U.S., where we anticipate paying a lot of attention to developments in both China and especially Japan.

A crystal ball with the word 'SP 500' written inside it (and 'Dividends' above it) - Image generated by Microsoft Copilot Designer.

The S&P 500's dividend outlook for the final quarter of 2025 brightened in the month since our last snapshot of their outlook.

On 15 October 2025, the CME Group's S&P 500 Quarterly Dividend Index' Futures quotes indicated investors could expect to collect $19.90 per share during the period covered by 2025-Q4 dividend futures contracts. On Friday, 14 November 2025, that rose to $19.94 per share, an increase of 0.2% from the previous month's outlook.

Our October 2025 snapshot also presented the projections for the S&P 500's dividends per share through the second quarter of 2026. Here is how the dividends expected in the future quarters of 2026-Q1 and 2026-Q2 changed in the past month:

  • 2026-Q1: Decrease of $0.01, dipping to $20.89 per share
  • 2026-Q2: Increase of $0.02, rising to $19.73 per share

For this dividend snapshot, we're extending the outlook for the S&P 500's expected dividends per share through the fourth quarter of 2026. The following chart presents the S&P 500's quarterly dividends per share as provided by dividend futures contracts from 2024-Q1 through 2026-Q4.

Monthly Snapshot of Past and Projected Future for the S&P 500's Quarterly Dividends per Share, 2024-Q1 through 2026-Q4, Snapshot on 14 November 2025

A note of caution on the dividend projection for 2026-Q4. Because it covers expectations that are currently more than four quarters into the future, it's best understood as an initial projection based on very thin trading at this point of time. The projection for this quarter can be expected to change once it falls within the typical year-ahead period that defines the typical time horizon for investors and the investment activity for its related dividend futures contract picks up.

More About Dividend Futures Data

How changes in the outlook for dividends at specific points of time in the future contribute to changes in stock prices is described by this math.

For this series, we have been taking a snapshot of the CME Group's S&P 500 quarterly dividend futures data shortly after the second or third week of each month.

Dividend futures indicate the amount of dividends per share to be paid out over the period covered by each quarter's dividend futures contracts, which start on the day after the preceding quarter's dividend futures contracts expire and end on the third Friday of the month ending the indicated quarter. As determined by dividend futures contracts, the now "current" quarter of 2025-Q4 began on Saturday, 20 September 2025 and will end on Friday, 19 December 2025. From the perspective of dividend futures, the next quarter of 2026-Q1 will begin on Saturday, 22 December 2025.

Because dividend futures are tied to options contracts that run on this schedule, that makes these figures different from the quarterly dividends per share figures that are reported by Standard and Poor. S&P reports the amount of dividends per share paid out during regular calendar quarters after the end of each quarter. This term mismatch accounts for the differences in dividends reported by both sources, with the biggest differences between the two typically seen in the first and fourth quarters of each year.
