The old man says the four-year cycle is dead. I don't think so. After all, this is a solid consensus that has been accumulated over more than a decade in the market. Looking back at each market top—except for the earliest exploration phase—in 2013, 2017, 2021, and the high point in 2025, the market has consistently followed a four-year cycle. The entry of institutional funds and changes in the macro environment actually only alter the short-term movement of the candlesticks. The overall trend remains irreversible because no matter how external capital bets, the big trend remains unchanged.
