Why is there this mentality? Because people can never imagine/assess the context correctly when they are in it. They only realize it when it's over.
Recently, I read the book "The Teacher" by General Nguyen Chi Vinh about Mr. Ba Quoc, Mr. Vinh's teacher, which has a very interesting detail: to pass the lie detector test to continue operating within the enemy's territory, Mr. Ba Quoc had to imagine losing for a night, taking on the role of a person who has experienced the losses of land reform, to hate his own organization. He passed the test smoothly to continue his mission.
When prices are at their peak, I read that many people decided to go all-in, selling land and properties, borrowing from family and friends to invest, perhaps because they did not know... to imagine like Mr. Ba Quoc. For example, a year ago, to anyone considering taking risks, margin trading, or borrowing, I said to imagine the scene of debt, ruin, family separation... then act.
Just stopping to type the order, sitting down to imagine the most disastrous scenario for just one night, would have prevented many tragedies from occurring.
Prices are the same; investors who "wish the prices would drop to the bottom to buy" surely cannot imagine the current context: The market makers always create an extremely pessimistic atmosphere when prices have been discounted, and often the crowd has run out of money.
In the end, those who "wish" often went all-in at the peak, and if they still have money, they are hesitant when the opportunity arises because when at the peak, they were so optimistic that they could never imagine the market could be so excessively pessimistic.
