A netizen asked Duan Yongping, after you buy a lot of company stocks, there will definitely be a period of significant stock price decline. How much did you lose at your worst, and how did you psychologically comfort yourself?

Duan Yongping said that after he bought Apple, there were several times when Apple dropped more than 40% from its peak, and even more times when it dropped 30%. He said he didn't pay much attention to it and didn't mind.
With decades of investment experience and many successful cases, Duan Yongping also couldn't buy at the lowest point or sell at the highest point, and he often encountered large setbacks.
But many of our stock investors expect themselves to do better than Duan Yongping, and some even mock him for not selling when Maotai was at 2600. Guizhou Maotai fell from its peak of 2600 to 1400, nearly halving, but during the same period, many blue-chip stocks retraced over 70%, effectively halving again after the initial halving.
Of course, some smart investors would say they sold Maotai to switch to banks. If you thought about selling Maotai at 2600, you probably should have sold it before it dropped below 1000. Where would you get the chance to sell at 2600?
We ordinary people also need to face this issue. As long as you choose good companies with stable performance and continued profitability, don't fear fluctuations. This might be the market giving you opportunities for dividends and reinvestment.
We should watch more videos of Duan Yongping, as they can save us a lot of opportunity costs and time for compound growth.
