At the beginning, the granularity research is coarse, it doesn't matter, and it is slowly eliminated. For example, you can screen by industry, then remove some according to business model, and then remove some according to assets and liabilities, etc. In each round of screening, only the best ones are retained and the poor ones are removed.

The logic of profiteering is less but better.Stock selection is to keep going through the sieve, from big holes to small holes, from coarse mesh to fine mesh, over and over again. Until the finest and highest quality stocks are screened out.For this great goal, keep fighting.

If it seems that there are not so many things you like, only one or two, then just hold these two and never settle for it. Especially when you are particularly optimistic and particularly sure, you can hold these two in a heavy position.If you are wrong, because your position is small and the loss of a single stock is relatively small, it is easy for you to cut your meat, because you don't feel bad, but if many stocks cut their meat like this, it will be a lot of money, and it will be a big loss.If you want to control the smoothness of the overall account, the position can be appropriately small, such as a medium position, and some funds can be reserved for better opportunities. In this way, you can attack and defend. You expect to go up, but you are not afraid of going down, because you are still a potential buyer, and you can do it more easily.
