Weekly Note - December 17, 2025

Performance Review

The table below shows performance figures for 2025 through last Friday (Dec 12) for two accounts following Focused 15 model portfolios, along with several alternative investments. The account following the Main model portfolio, shown in the gold box, returned 14.0 percent. A measure of risk, defined as the variability of weekly returns and indicated by the standard deviation, was 5.9 percent. The ratio of return to risk for the year to date is therefore 2.4.

Return indicates how your account grows over time, and higher is better. The 14.0 percent return is similar to that of the Dow Jones Industrial Average ETF, DIA, and the Schwab Balanced Fund with a 60 percent stock and 40 percent bond allocation, SWBGX. This result is generally consistent with expectations for the Main Focused 15 portfolio.

The variability of returns indicates how smoothly the account grows over time. Lower variability is better. Although variability is more abstract than return, it is useful for comparisons across investments. The 5.9 percent variability for the Main model portfolio is less than half that of the DJIA ETF and slightly lower than that of the most conservative Schwab fund, which has a 40 percent stock and 60 percent bond mix, SWCGX. It is lower than all of the alternative investments shown.

The combination of strong returns and low variability results in a high return-to-variability ratio of 2.4, which is significantly higher than the alternatives listed. This indicates that the Focused 15 portfolios have delivered high returns for the level of variability incurred.

This information is useful for several reasons. First, it suggests that the portfolios have been successful in avoiding losses while participating in stock market gains, which is the objective of the trading process.

Second, the high ratio suggests that the investment process may continue to reduce losses going forward.

Third, the lower level of variability allows investors to more comfortably use a more aggressive model portfolio than they otherwise would. By following a more aggressive Focused 15 model portfolio one can get higher returns and still have a level of variability that is comparable to the Schwab balanced funds, which are often used for retirement accounts.

One account I monitor uses a model portfolio that is always one step more aggressive than whatever model portfolio is designated as the Main portfolio. The aggressiveness of this account can be described as “Main  +1.”  That account returned 15.6 percent for the year-to-date period, which gives it higher returns than the fund “SWBGX.” Unfortunately, comparable variability-related data are not available for this account.

Selecting a Level of Aggressiveness

For those with a relatively short investment horizon, the Main model portfolio, which I personally use, may be appropriate. For those with longer investment horizons, such as investors in their 20s and 30s, more aggressive portfolios that are always one or two steps more aggressive than the Main model portfolio may be appropriate. See page 3 of the weekly report for return and variability information for the full range of model portfolios. 

Over the course of 2026, the gold box representing the Main model portfolio may shift to take advantage of the market dynamics described below. You only need to remember how many steps above or below the Main model portfolio you have selected as your long-term position.

2026 Outlook

I do not usually provide a 12-month outlook, but 2026 is likely to be unusual. The information below does not require you to change anything about how your account is managed, other than continuing to follow your selected level of aggressiveness (e.g., Main +1, or Main +2).

If historical precedents over the past 100 years continue to apply, the stock market is likely to experience a boom-and-bust pattern over the next 12 months. There have been 13 such episodes since 1935, with the most recent occurring in 2017 and 2018. One of the largest episodes in recent memory was in 1987. The DJIA peaked in August of 1987 following a 54 percent gain over the prior 12 months. After this market boom, the DJIA experienced a 35 percent loss over the following four months.

The next boom is likely to begin over the next several weeks and will reach its peak in approximately May of 2026. Depending on the strength of the boom, I may shift the Main model portfolio to a more aggressive model portfolio.  

Research on Physics-based Drivers of Investor Sentiment

The forecast above is based on over 90 years of long-term cycles in stock market performance and their relationship to solar energy variation. A paper describing this research is available on a preprint service at the following location.

       https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5482086

Feel free to download the report and to forward the link to anyone who might find the information useful. 

To date, I have not changed the investment process based on this research. The research findings however, make implementing the target weights less stressful. They help us identify when the market is performing as expected and when it may be vulnerable to declines if economic conditions require a rapid adjustment in stock prices. At times, these periods of naturally occurring vulnerability can be anticipated several months in advance. The potential 2026 boom-and-bust episode is one such case.

Historically, the Focused 15 algorithms have been successful in participating in market booms. Busts, however, tend to begin abruptly, and the algorithms typically take a few weeks to adapt to the rapid shift toward negative investor sentiment. At this time, we cannot know how strong the boom might be or how severe a subsequent bust could become. The magnitude depends on economic and market conditions at the time. The timing of periods of vulnerability, however, is driven by naturally occurring cycles of investor sentiment described in the paper. As a result, we have a reasonably good sense of when the market is most vulnerable to a downturn.

We will not make a change based only on this research. Any boom will need to be identified and confirmed by the Market Resilience Indexes (MRI). As of this writing, the Macro MRI is shifting to a more positive trend, which could indicate the beginning of the boom. 

If historical precedents hold, market returns are likely to strengthen in January or February and continue through the spring, with a potential peak in late May or early June. June and July are likely to be periods of heightened vulnerability to a market decline. If economic conditions remain positive, the market may recover quickly, followed by a final vulnerable period toward the end of the year.

With this perspective, I currently expect to make these changes once it is clear that the boom period has begun:

1.      Increase aggressiveness of accounts for the several months prior to the peak, beginning at the end of 2025 or early 2026.

2.      End that period of aggressiveness just before the expected peak of naturally occurring resilience, roughly mid-May. 

3.      Increase aggressiveness in July.

4.      Decrease in late December or early January 2027

You do not need to take any unusual action during these shifts. Simply continue to follow your selected level of aggressiveness relative to the Main model portfolio (e.g., Main +1, Main +2). Also watch for a change in the Box #2 Cash level, which may change if the markets appear to be making an abrupt decline close to an expected period of naturally occurring vulnerability. 

Again, please let me know if you would like to have a call to discuss these issues.

6/04/2025

Note - June 4, 2025

The markets are recovering from the tariff turmoil earlier this year.  The MRI readings for the DJIA indicate the status of stocks in general (as of May 30, 2025):

DJIA                            Percentile        Direction         Comment

  Micro MRI                  82nd                 Positive            Cannot go much higher

  Macro MRI                 66th                  Negative           Can move much lower from here

  Exceptional Macro     Not present                                Not close to providing resilience

This set of conditions indicates that the long-term trend of the market is negative and that the short-term rally in the stock market is nearing an end.  The Micro MRI cannot keep rising.  When it turns to a negative trend this week or next, none of the three MRI will be providing resilience.  That set of conditions will be unfavorable for the stock market.  Any negative news will produce a more negative move in prices than if the same news occurred during more resilient conditions.

Other US stock indexes show similar conditions.  The Micro MRI for the S&P 500 is even higher than the DJIA’s, and the higher level and negative trend of the Macro MRI suggests that the price of the S&P 500 can fall even more dramatically from this level compared to the DJIA.

S&P 500                   Percentile        Direction         Comment

  Micro MRI               93rd                  Positive            Cannot go much higher

  Macro MRI               77th                  Negative          Can move much lower from here

  Exceptional Macro    Not present                              Not close to providing resilience

The NASDAQ also has a negative trend in its Macro MRI and the Micro MRI is at a high level. 

NASDAQ                    Percentile        Direction         Comment

  Micro MRI                 74th                  Positive            Cannot go much higher

  Macro MRI                 75th                  Negative          Can move much lower from here

  Exceptional Macro      Not present                             Not close to providing resilience

Our algorithms will not respond to the high level of the Micro MRI.  Instead, the more successful strategy historically has been to wait until the Micro MRI has made the change to a negative trend.  I suspect this negative trend could be established this week or next.  The expectation would then be the beginning of a meaningful market decline.

If the Macro MRIs listed above had positive trends the outlook would be different.  Upward price moves could take place, albeit at a slower pace. 

A good case can be made that the negative trending Macro MRI for the US stock indexes is the result of the tariff turmoil of earlier in the year.  If that turmoil is now over, the market might treat it like a natural disaster. When a disaster strikes, the market may falter for days or weeks but will soon resume its prior path.  If this is the current scenario, the negative trending Macro MRIs will soon resume their upward trends. The algorithms can accommodate this. 

The algorithms for the DJIA current are leaning toward a resumption of an upward trend, while those for the S&P lean toward a continued negative trend and a new “Sell” rating this week.  Those for the NASDAQ are borderline.  All of these leanings close to the borderline can change meaningfully in one week. 

It is important to note that the naturally occurring long-term shifts in sentiment favor optimism, which suggest that prices can move higher from here and widespread panic is not likely.  This suggests that the negative Macro MRI trends are related to current economic conditions as opposed to naturally occurring cycles. 

The bond market is stressed.  It has struggled and pundits say it will continue to struggle as long as the US budget deficit problems remain inflamed by poor management of spending and tax receipts.  Our metrics for the US 10-year bond index is for it to become less resilient in a week or so, potentially sending yields higher.  This type of event is usually a negative one for the markets short term. 

Thus, the medium-term trend in the stock market that is relevant to us depends on the US administration’s actions.  A steady hand will steady the markets. 

If we look overseas at the EAFE Index, its MRI conditions are different.

EAFE                          Percentile        Direction         Comment

  Micro MRI                  29th                 Positive            Can go much higher

  Macro MRI                 49th                  Positive*          Can go higher

  Exceptional Macro      Present                                     Is currently providing resilience

The condition for EAFE companies is more positive (*the Macro MRI recently changed to an upward trend, which is an optimistic indicator for the ETF) and may not have the negative effects of domestic US issues. However, it should be noted that the long-term performance of US stock indexes has been much better than non-US stock indexes.  Also, it is often said that if the US sneezes everyone else catches a cold. Thus, the addition of the EAFE ETF may not be a long-term solution. But it may present an alternative to the US indexes until our domestic issues are resolved or, at least, stabilized.

 

2/19/2025

Weekly Note - February 19, 2025

The target weights this week call for a slightly higher weight in the commodities ETF “COM." Overall, our portfolios are very conservative. Their conservative posture is determined by algorithms based on current conditions of the stock market compared to what has happened over the last 100+ years.

MRI TRENDS


In the current situation, the short-term dynamics of the stock market tracked by the Micro MRI lack strong direction. In similar historical conditions, it has been best to take money out of the stock market for a few weeks and let a stronger trend develop. When the market has lacked a strong direction, it most often has led to the market moving lower.

This lack of direction contrasts with a more common situation when one or more of our MRI begins the downleg of its cycle at a very high level. We see these situations when an MRI is at a high level of, say, the 70th percentile or higher and shifts to the downleg of its cycle and has a negative slope. Based on the high percentile, the downleg tends to have a strong direction.

As of last Friday, the Micro MRI for the DJIA was at about the 41st percentile of levels since 1918, which is roughly mid-level. It has been at about this level for approximately a month and has had both a positive and negative slope over that time. In Figure 1 below, the yellow ellipse shows the horizontal trend of the Micro MRI over the last month.

Figure 1 – ETF DIA (Tracks the DJIA)

It is this horizontal trend that has historically been followed by market price declines in most, but not all, cases.

Also in Figure 1, we see that the Macro MRI is at the 70th percentile and currently registers as being in the upleg of its cycle (“pos”= positive slope). It shifted to a positive slope from a negative slope over the last three weeks. Thus, it too has lacked clear direction over recent weeks.

As mentioned, the target weights are determined by an analysis of current dynamics compared to market history. For a look into the future, we now have the drivers of investor sentiment that highlight periods of naturally occurring optimism and pessimism. Historically, major market declines occur during periods of naturally occurring pessimism.

These drivers indicate that the market is likely to become more pessimistic in approximately the month of March (plus or minus a week or so). During this period, investors are likely to have the most pessimistic bias compared to recent months. Naturally occurring optimism will begin in roughly April. Thus, if there is an economic need for a price decline, March (roughly) will be the most vulnerable month in the early part of 2025.

VALUATIONS

One measure of an economic need for a stock market price decline is valuations. Figure 2 below shows the Price/Earnings ratio for the S&P 500 since records began in 1874.

Figure 2 – S&P 500 Price/Earnings Ratio


        Source: https://www.multpl.com/s-p-500-pe-ratio/table/by-month

At the far right is the most recent reading of 30.7. This is high by historical standards, although not at the highest levels. The Price/Earnings ratio decreases when the price drops and earnings stay the same, or when the price stays the same and earnings increase. Thus, high Price/Earnings ratios are often followed by stock prices that stay roughly the same or decline. Thus, a conservative stance makes sense.

INFLATION


Inflation is spiking, which tends to boost the prices of commodities. Thus, our commodities ETF “COM” has a higher weight. High inflation tends to hurt bond prices and, as a result, our bond ETF “UST” has a slightly lower weight.

Inflation also tends to result in higher stock prices because companies pass on to customers the higher prices of what they need to produce their products. Thus, if inflation continues, we could see the stock market becoming more resilient.
