The upward bull market is like an inflated balloon. As the balloon gets bigger, the risk of explosion will become higher and higher. We don't know when the balloon will suddenly explode. If the balloon suddenly goes down and the bull market plummets, can you bear it? Can you bear it objectively, economically and psychologically?
Look at the objective economy first. Many people's investment habits are like gambling. When the market is good, they will enter the market and make a lot of money. There are crazier people. When they saw that everyone said that a bull market was coming, they put all their wealth into the fund market, hoping to make a turnaround overnight. But buying a fund is not a business that only makes money without losing money. People who buy funds with the idea of making money without losing money advise you to withdraw from the market as soon as possible, put your money in the bank and buy wealth management, otherwise it will be ugly, and no one can accurately judge when the bull market will start and end.
That's a psychological problem. Simply put, how much money is psychologically acceptable to you? Of course everyone is happy when making money, but what about losing money? Some people have a correct attitude and know that since they want to make so much money, they have to accept the possibility of losing so much money. Some people lose a little money and start to suffer like cutting meat. Such people still suggest considering financial management in a bull market or a bear market.
If the balloon in the bull market bursts, whether you can bear the consequences is your bottom line, which determines whether you are suitable to buy funds in the bull market.
