Here are 2 monthly cycles, gold and oil, that are mirror images. Gold is headed lower and oil is due to move higher. Here are 4 graphs: monthly cycles and sentiment graphs that make the point.

As to gold, the initial peak in January was the start of an A wave. The March 2-3 top appears to be the start of a C wave (or a 3) down. The 23.6% retracement level has been passed. The 38.2% retracement level is $4,150, and the 50% retracement is $3,700. Here are the targets:

1.383 = $3,660
1.50 = $3,578
1.618 = $3,496

It appears that the low in this down move will be near $3,600-$3,700.

Sentiment is measured by dividing the leveraged gold ETF by its unleveraged ETF. Note the sentiment ratio has already begun to decline. The extreme bullishness is beginning to wane, but it is a long way from a buy signal.

UGL/GLD Gold Sentiment Ratio Has Hit The Sell Level

Here is the same approach as applied to the oil market.

After the sharp move up, price has not retreated by much. The rally created what appears to be a breakaway gap which usually marks the start of a move. The cycles still point up. It appears that a consolidation is underway, not lower prices. The price range runs from $87-$101.

From February 21 through May 21, price has increased 76.2% of the time for a 5.21% gain. This is true for any year. Because the monthly dynamic is also rising, the odds rise to over 83%.

These bullish readings imply that matters in the Gulf will not go well.

Soybean Prices - A 1986 Extrapolation
by Gertrude Shirk
Editor of the Cycles magazine and Vice President of the FSC

From the Archives: This article is reposted as it was published in Cycles Volume Thirty Seven - 1986.

The 1985 extrapolation of soybean prices, first published in the January/February 1985 issue of Cycles is reproduced below as Figure 1. The "How It Came Out" section of the actual price line is completed through December 1985. The prices used in this work are the average monthly cash price of No. 1 Yellow soybeans, Illinois Processor.

Fig. 1: Actual and Calculated Soybean Prices - 1985 Extrapolation

The yearly average on a calendar year basis of the calculated line for 1985 was $6.07 which compares to the actual calendar year average price of $5.64 that occurred. In early 1985, low level of the extrapolated calculated line was considered by some members interested in soybean prices to be unduly pessimistic. But, as it turned out, the calculated line ran consistently above the actual prices as they developed.

The calculated/actual price chart covers only five years, and a better perspective can be gained from the entire history of soybean prices. Figure 2 shows this history by crop years, beginning with the figure for the crop year 947-48, and continuing through 1984-85.

Fig. 2: Annual Average Soybean Prices - Crop Years 1947-8 Through 1984-5

This chart is a ratio chart, one on which equal distances measure equal percentage changes. It is obvious that since soybeans have moved to a level of 60 cents and more that the percentage changes from year to year have been much greater than during the earlier period.

The end portion of Figure 2, beginning with the figure for 1972-73 is enlarged on Figure 3, and two possible trend lines are added. The level and direction of trend are important considerations because cycles operate around — above and below — the trend. Although it is tempting to consider the straight line trend as the best description of trend, it is also possible to arrive at a different description — as shown by the bowed line. The top straight line trend gives a 1985-6 value of $6.89 compared to about $6.50 for the curved line.

Fig. 3: Annual Average Soybean Prices - Crop Years 1972-3 Through 1984-5 Together With Two Trends

In any event, actual prices through February 1986 have been well below these trend levels for many months, and the yearly average trend that was used to prepare a 1986 calculated line averaged $5.75. By historical standards (the two trends on Figure 3) the value of $5.75 is low, but it is above the last eight month's experience.

The cycles that were combined with trend were the 12-month, the 24.56-month and the 38.6-month. The record of the 24.56-month cycle is shown on Figure 4, and the 38.6-month cycle is recorded on Figure 5. Both charts are marked to show how the cycle has performed since it was first defined.

Fig. 4: The 24.56-Month Cycle in Soybean Prices

The 24.56-month cycle has an average amplitude of 10% of trend at the time of an average crest. There was an ideal crest at May 1985, and the model pattern is now on the way down to a trough at May 1986.

The 38.6-month cycle has an average amplitude of 12% of trend at the time of an ideal crest. The ideal cycle is now going up to a crest at October 1986. Since the low on the seasonal cycle occurs at October, it will be interesting to see what is actually occurring to soybean prices come October.

The combination of the assumed trend and the three cycles is shown on Figure 6 as the broken line.

Fig. 5: The 38.6-Month Cycle in Soybean Prices

The cycles used here measure as being statistically significant. That is, the numbers are good. But, even more important is the degree to which these cycles have functioned since they were first postulated.

The average seasonal pattern in soybean prices that was used in the combination is as follows:

Per Cent of Yearly Trend

Of course, our interest is in the cycles. An extrapolation of the sort shown on Figure 6 will show not only how well the cycles operate, but will also test the conclusion about the best trend level to use. In addition, all the factors used can be seriously perturbed by random, non-cyclic occurrences.

In the January/February 1986 issue of Cycles magazine, Gertrude Shirk reviewed the performance of cycles in soybean prices previously discussed in Cycles 50 years ago, in the February 1976 issue.

The article made some short-term forecasts based on 12-, 38.6-, and 24.56-month cycles. I wanted to see if a calibration of those cycles made in 1986 would have given a helpful forecast for the time ensuing since.

Our data source is FRED, courtesy the Federal Bank of St Louis.

This is their monthly history of the Soybean Producer Price Index since 1947. They use 1982 as the base for the index.

FRED — Producer Price Index by Commodity: Farm Products: Soybeans

Note: This analysis uses the FRED® API but is not endorsed or certified by the Federal Reserve Bank of St. Louis.

In 2026 we can vibe code a model that best fits these three cycles to the period 1947 to February 1986 and see how well they have played out since then.

For convenience I used the price gradient (monthly proportionate difference) rather than the raw price, as it is less influenced by the long-term trend but should show similar cyclicity with price turning points occurring at gradient zeros.

A differential evolution algorithm calibrated the phase and amplitude of the gradients, using data from 1947 to 1986, which allows the cycle forecast gradient to be projected from 1986 to the present day and forward to 2030.

Here are the results of the projection, firstly for the last 50 years. The grey-shaded period shows projected gradient, with projected price highs and lows marked with red and green lines respectively.

It is a matter of debate whether cyclic behaviour in financial time series is endogenous (down to the interaction of opposing forces within the system) or exogenous (driven by some external clock).

The distinction is more than academic, because the equations governing endogenous cycles are very sensitive to tiny changes in their parameters. Systems like these can be fundamentally chaotic and unpredictable. On the other hand, exogenous cycles endure over time, so they can be calibrated given sufficient data and they can be modelled with more tractable mathematics like Fourier analysis. While time-local circumstances can shift timing of individual cycles, in the long run the turning points for exogenous cycles remain close to predicted times.

Analysis like this brings evidence to the debate.

The work of the Foundation has identified many apparent exogenous cycles, the work to consolidate and explain them continues.

The U.S. stock market indices are likely headed higher into January. There are four reasons for this projection.

First, this is a year ending in a 5, the strongest year in the 10-year decennial pattern as developed by Edgar Laurence Smith at Ameritrust Bank. All questions in such "5" years are resolved on the upside. September has been the weakest month in any year, but this bearish month has closed on the upside 66% of the time in these "5" years. The weakest part of September has been the second half of the month, especially the last week. This period could present favorable buying opportunities.

We’re proud to announce a landmark collaboration between two organizations deeply committed to the future of market analysis and financial education: the Foundation for the Study of Cycles (FSC) and the International Federation of Technical Analysts (IFTA).

Last week, during the Live in ’25 conference in New York City, FSC and IFTA formally signed a Memorandum of Understanding (MoU) – a milestone that marks the beginning of an exciting new chapter in the global advancement of technical and cycles analysis.

Dr. Richard Smith and Wieland Arlt sign MOU

A Shared Vision for Empowering Analysts Worldwide

This strategic partnership is built on a shared mission: to empower technical analysts and market practitioners with world-class training, cutting-edge research, and an engaged global community.

For decades, both FSC and IFTA have championed professional excellence in the field. This collaboration takes that commitment to the next level, creating opportunities for deeper learning, broader networking, and stronger professional influence.

Key Areas of Collaboration

The MoU outlines five core areas where FSC and IFTA will work together:

  • Knowledge Sharing: Co-produced white papers, research, and webinars that explore technical and cycles analysis, market trends, and the evolution of the field.
  • Professional Development: Joint training programs, workshops, and certifications to equip analysts with the tools they need to succeed in a fast-changing landscape.
  • Events & Conferences: Co-branded events ranging from intimate roundtables to global summits – bringing together thought leaders, innovators, and rising stars.
  • Networking & Community Building: Cross-membership benefits, priority access, and more ways for members to connect, collaborate, and grow.
  • Advocacy & Industry Impact: Joint campaigns and policy initiatives aimed at shaping the future of our profession and elevating the role of analysis in financial decision-making.

Why This Matters Now

As financial markets grow more complex and interconnected, the need for skilled technical analysts has never been greater. Technical analysis offers powerful tools to decode market behavior, identify trends, and anticipate reversals – all through a disciplined, data-driven lens.

At the same time, cycles analysis adds a unique and vital dimension, highlighting the time-based rhythms that influence everything from stock prices and commodity markets to economic cycles and human behavior. With over 80 years of leadership in this space, FSC brings unmatched expertise in the study of recurring patterns rooted in both nature and finance.

By combining these two approaches – technical analysis and cycles analysis – this partnership equips professionals with a broader lens and a sharper edge.

What Comes Next

This is just the beginning. In the months ahead, FSC and IFTA members can look forward to:

  • New co-branded educational programs
  • Exclusive webinars and research insights
  • High-impact joint events
  • Expanded community engagement opportunities

Together, we’re building a stronger, smarter, and more connected future for the global technical analysis community.

We invite all members, partners, and fellow market practitioners to join us in this journey. Let’s shape what’s next – together.

Dr. Richard Smith and Wieland Arlt sign MOU

The S&P and NASDAQ indices, both weighted and unweighted, have broken out of consolidations. The cycles for both indices point up, so higher quotes are likely. The prior resistance is now support, and price is sitting just above these support areas. This establishes an attractive reward/risk ratio in each market. Newsletter writers have gone from bullish to very bearish quickly. And now the AAII survey has more bears than any time in the last year.

In the summer of 2024, I noted that the stock market was likely to move higher. However, the big tech leaders were seen to be too extended and due for a correction. If the market was to move higher and the tech leaders were to correct, then other stocks would have to start outperforming, which has been the case. Let us analyze the prospects for these stocks through the use of cycles.

The relative strength of the equally weighted NASDAQ versus the S&P 500 turned up in late December and remains strong. This indicates that the average stock in the NDX 100 is stronger than the cap-weighted S&P 500. The big-cap tech stocks have been lagging while the smaller weights in the index have been rising. The result: Many more stocks are rising, but the equities that have the greatest influence on the indices have lagged. This is in sharp contrast to the situation in 2024 in which only 25% of the stocks outperformed the S&P 500.

The relative strength screen shows that within the NASDAQ 100, the big 8 tech stocks are ranked from number 6 (Netflix) to number 75 (Microsoft). Here are the stocks in relative strength order with the cycles' recommendations in parentheses:

  • Netflix (hold)
  • Meta Platforms (sell)
  • Tesla (buy)
  • NVIDIA (sell)
  • Amazon (sell)
  • Apple (hold)
  • Google (sell)
  • Microsoft (cycle low in March)

This monthly cycle explains the buy signal on Tesla:

Here is another picture that explains the sell opinion on NVIDIA:

The top 5 NASDAQ current relative performers are:

  1. Palantir
  2. Super Micro Computer
  3. Axon
  4. Atlassian
  5. DoorDash

From these new leaders, here are the stocks that can be added to portfolios now.

Super Micro came down hard, bottomed, and is now giving longer-term buy signals, supported by rising cycles.

From the Archives: This article is reposted as it was published in 1970 in the Journal of Interdisciplinary Cycle Research - Volume 1.

Probably more than a thousand scientists, the world over, have studied rhythmic behaviour of one sort or another. They have reported over 500 different sorts of phenomena which have been alleged to fluctuate rhythmically, i.e., in cycles or waves of reasonable regularity. Rhythmic cycles characterize the abundance of animals, the variations of weather, the recurrence of diseases and epidemics, the repetition of basic physiological phenomena, the ups and downs of business, the widths of tree rings, the fluctuations of lake levels, the thickness of sedimentary rock deposits, the outbreak of volcanic eruptions, the occurrence of earthquakes, the number of sunspots, etc., almost endlessly.

The problems of rhythmic behaviour in all these various and unrelated phenomena have, however, one thing in common: The techniques of time series analysis should be largely the same, regardless of the nature of the phenomena being studied. A 9.6-year cycle in wolf abundance in Canada should be studied, statistically, in much the same way as a 9.6-year cycle in the run-off of a river in India.

Moreover, all the various cycles that have been found have one thing in common: When they are statistically significant, i.e., when they have repeated with enough dominance and enough regularity and enough times so that they cannot reasonably be the result of chance, they help us to throw light on the future. They do this whether our interest is in international conflict, immigration, earthquakes, solar radiation, meteorological, economic, biological or medical cycles. However, these two points of similarity in TECHNIQUE and USE are not, by themselves sufficient reason to propagate interdisciplinary cycle research.

When comparative studies are made of the cycles alleged to be present in various scientific fields, it is found that the periods are often the same. This is true not only for phenomena in the same discipline, but for completely unrelated phenomena. Of course, in many instances similarity in cycle periods may occur by sheer coincidence. However, there seems to be a non-chance distribution of the observed periods, i.e., many examples of certain periods are found but few or no examples of other periods. Moreover, cycles with the same period tend to have a turning point at the same calendar time regardless of phenomena or discipline. At this point, cycles become a matter of interdisciplinary concern.

Naturally, some of the cycles that have been alleged are merely accidental regularities of random fluctuations. On the other hand, there are reasons for thinking that many of the cycles are meaningful. For instance, many cycles have high statistical significance; they continue over many repetitions and continue over long spans of time unchanged, despite changed environmental conditions; cycles often dominate the behaviour of animals and man; they often show evidence of geographical patterns, i.e., cycles of the same period, regardless of phenomena, seem to come later and later as found from pole to equator; after distortion, cycles revert to the predistortion phase.

It is often assumed that many of the biological cycles have an endogenous origin. Such endogenous cycles can have high statistical significance, can repeat many times with great regularity, can be dominant, and, by shear coincidence, could have more or less the same period.

On the other hand, it would be extraordinary difficult for cycles of the same period in completely unrelated phenomena to turn at approximately the same time and to have geographical latitude patterns, unless the cause of the regularity were external to the phenomena involved.

The suggestion is thus inescapable that there may be hitherto unsuspected environmental forces which affect terrestrial affairs and determine the time of the ups and downs of many phenomena of interest and concern to mankind. Studies in recent years suggesting very long-term rhythmic fluctuations in a number of biological, medical, and inorganic phenomena strongly support this assumption. Under these circumstances the subject of comparative cycle study would thus seem to be a must for further investigation.

Some people will be interested to explore these possibilities. However, more scientists will prefer to confine their studies to cycles in their own disciplines. People with the latter interest can be most helpful to the major field of interdisciplinary study if they will determine the period of the cycles they study with the greatest possible accuracy; determine, in each instance, its statistical significance; record the latitude and longitude of the phenomenon evidencing the cycle; supply the data; explain the methodology in full; idealize the cycle, and, as important as anything, record the timing of the idealized cycle. Such studies are the bricks of which the larger structure is created.

No one can say whether or not the bricks are more important than the building. We need both. One must work in the area of one's interest. However, if it should be true that there are environmental forces that cause, or at least trigger and/or time the ups and downs of all aspects of human life, it becomes a matter of profound practical and philosophical importance and a challenge for every scientist interested in the broader aspects of the problems of the living world.
