Most traders, even when the market rises to a suitable level, remain overly greedy, always hoping the price will continue to surge, unwilling to take profits and exit.

By the time the market turns downward, profits are quickly wiped out, and losses are incurred, leading to regret.
Many are still blindly fantasizing about a continued rally, ignoring the negative signals brought by profit-taking at high levels.
Even large investors are taking the opportunity to exit and hedge risks, while ordinary participants stubbornly hold their positions, clinging to luck, ultimately giving all their gains back to the market.
