According to the 20th-century market technician George Lindsay, almost all stock market activity on the Dow Industrials can be classified as either a Basic Advance, Basic Decline, or Sideways Movement.
A basic advance usually lasts 2 years and 2 months (average is 795 calendar days), but in Linday’s 20th century market analysis, he found advances ranging from 414 days to 968 days.
A basic decline typically lasts 12 months (365 days), but in Lindsay’s analysis, durations ranged from 226 days to 446 days.
Within the time ranges shown above, Lindsay further classified advances and declines (e.g. Short Advance, Long Decline), and he believed that these classifications had relevance to market forecasting, but I do not find this level of detail relevant to the Dow in the modern era. Nevertheless, a more detailed discussion of Basic Movements can be found in Ed Carlson’s 2011 book George Lindsay and the Art of Technical Analysis.
Another type of Basic Movement is “Sideways.” A sideways movement usually lasts for several months. The maximum length that Lindsay found was 11 months. He warned that an 11-month sideways period followed by a basic advance foreshadows a 1929-style crash. Interestingly, there was an even longer sideways period during 2004-05 (14 or 20 months depending on how you count it) followed by an advance into 2007. If one recognized this Lindsay scenario, the 2008 crash would have been predictable.
Basic advances and declines do not always start from the absolute low/high point. For example, after the start of a basic advance, the market can make a modest new low before a sustained uptrend begins. This makes short and intermediate-term forecasting based on basic movements rather difficult.
The chart above shows the Basic Movements from the 2009 low to present on the Dow (DIA ETF). I think that a basic advance began from the December 2018 low and lasted until May 2021. Even though the covid crash occurred in the middle of this advance, I still think the period qualifies as a basic advance for the following reasons:
- There was a very clear basic decline from January 2018 – December 2018, which followed a very clear basic advance from February 2016 – January 2018. I cannot find any other way to count 2016-2021 without having a basic advance that is too long or a decline that is too long.
- During the covid crash in February-March 2020, the Dow spent very little time below the December 2018 low
In May 2021, the Dow became increasingly choppy despite continuing to churn to new highs. I think the increased volatility from this point onward was due to the Dow entering a basic decline. The typical length of a basic decline is around 12 months, so the low in June 2022 came right on schedule.
Thus, I think that a new basic advance is underway now, which will likely last until mid-2024, or at the very latest January 2025.
Also shown on the chart above is the Lindsay Long Cycle that started at the 2009 low. The idealized schematic for the Long Cycle is shown below:

In our current situation, Point E came right on schedule in 2016. The Long Cycle now predicts an eight-year interval from 2016 to Point J, which projects the Point J top to occur in 2024. Interestingly, this is when the current basic advance is scheduled to end.
Following the top in 2024, there will likely be a basic decline ending in 2025-26, then a weak advance into 2027-28, then a more severe decline into 2028-29.
