description: "Key points to consider1. Whether it's truly a good stock2. Where to place the strike zone3. How much position size is appropriate for each purchase when building a position in batches? When you don't have unlimited funds, will it impact the overall account's risk control?4. A significant drop in a stock's price must have its reasons, often involving various scary stories. This brings us back to point 1: how to determine if it was unfairly sold off, or if there's a fundamental deterioration or the industry's moat has been breached?5. When executing steps 1-2-3-4 and finding yourself heavily invested, only to realize it was a misjudgment, can you make an accurate decision in time, calmly cut losses, and move on to the next round of judgment?I think each of the above points has a certain degree of difficulty, even considerable difficulty. Therefore, I believe investing is not as simple as saying "buy more as it falls on the left side" or "go all-in chasing a breakout on the right side." The essence is still betting on your own valuation judgment—"Where do I think this company is headed?""
