I saw a statement in the US stock group: someone said that after Lei Jun of Xiaomi became the richest person, he heavily shorted Xiaomi, with the logic that entrepreneurs who become the richest usually don't have a good ending.

Using the same logic, after Huang Zheng of Pinduoduo became the richest person (in 2024), shorting also yielded good returns.
In China over the past years, after the richest person in the real estate or consumer goods industry reaches the top, they are often close to the industry cycle peak.
