This YouTube video ("The Power Law Is Strong As Ever" by Kosta Ouzas) discusses market cycles and how peak values in financial data decay over time. The speaker describes an exponential decay applied to peaks during bull runs, asserting that peak magnitudes become smaller over time and can be measured and modeled from past data.
When the bull run starts, when it ends, and so on. And also it has some kind of a decay, an exponential decay, to account for the decay of the peaks. So over time, these peaks are becoming smaller, and you can calculate them, because even these, at least if you use a past data, it's predict, let's say not predictable, but measurable, and you can make a model out of it.
