Market cycles are not a real thing, its a made up concept which the large investment firms want you to think occur so they can justify moving your money from X to Y during "parts of the cycle".
They do this because they only make money by moving your money, not by holding it, since transaction fees are far higher than yearly annual fees (compare the fees of moving $1M in assets four times in a year with a fee of 1% for each movement vs a single flat annual fee of 0.5%), particularly since indexing now exists and has driven fees down. Objectively, you make more money holding your assets forever without moving them, since you avoid transaction fees as well as taxes.
If you dont believe me just go look at the accumulation index of the SP500, an economy which is supposed to have a 'typical market' cycle. You might notice its a near perfect ascending straight line, the 'cycles' don't even exist on it.
What does exist are times of overpriced and under priced assets, but price fluctuation are entirely based off emotions, not actual value, and cant be predicted because of that.
