What happens to popular stocks at the end of a bull market, as per Schabacker's Rules?

According to Schabacker's Rules, at the end of a bull market, popular stocks often experience a collapse while other stocks might rise or maintain their momentum. This occurs due to a variety of market dynamics, including profit-taking by investors who want to lock in gains, leading to increased selling pressure on these well-known stocks that have reached strength in price and popularity during a bull market.

As the market sentiment shifts, the demand for these previously popular stocks can diminish, causing a decline in their prices. Meanwhile, less popular or lesser-known stocks, often with higher potential for growth or undervaluation, may start to gain traction, leading to a divergence in performance between popular stocks and others. This reflects the market's tendency to rotate into different sectors or opportunities as investors reassess their strategies in changing market conditions, typically at the later stages of a bull market.
