My cycle analysis also shows a sell off in January 2020.
IMV... any kind of "cycle" analysis is among the least reliable.
Years ago when Steve Shellins ran the MoniResearch Newsletter, he commented... "those who claim cycle analysis as their primary methodology are the worst performers". (His service tracked ~225 money managers.) Which performers were the best? Those who claimed "Relative Strength and Sector Rotation" to be their methodology.
Is not Sector Rotation a "cycle" itself?
