Tell an interesting story: there are two friends, one of whom holds A-shares. The A-shares dropped by 5 points the day before, and my friend felt a bit unhappy. I comforted him by saying: as long as the company is fine, it will rise again.

I don't understand A-shares, I can only comfort him, hoping he understands it himself.

Previously, I also said that if you have a good understanding of A-shares and confidence, such a drop could even be a reason to increase your position.

The next morning, when the market opened, A-shares rose by 2 points. The other friend said it was good to have increased the position yesterday.

I said: you are right. This just happens to illustrate a point: in hindsight, everyone knows to increase their position; why didn't they do it beforehand? Because it's unpredictable; people can't predict today's rise in advance, so they can't increase their positions.

For me, it's because I don't understand A-shares, and I could never increase my position anyway. For short-term trading, due to its unpredictability, it's impossible to accurately increase positions. For those who don't understand the company in short-term trading, who would dare to increase their position amidst a 5% drop? Furthermore, if you had increased your position yesterday and it still dropped today, what would you do? Waiting to break even could take an indeterminate amount of time.

Therefore, investing still requires a deep and thorough understanding of the company; a solid and strong business foundation is essential. When you clearly understand that the fluctuations of the capital market do not fundamentally affect a company's ability to generate more cash, that’s when it’s time to invest.
