#我的COS交易 I am very optimistic about COS. Although it is currently at a bottom position, this allows me to buy it better. I believe that owning COS can bring me a good return. It maintains a low horizontal position, with bottom trading volume gradually increasing. Combined with fund flow and sentiment indicators, it is suitable to try to purchase with a small position first. It should be noted that the main force's rise is fast and the pullback is deep. I feel there is a great opportunity, and I believe it has a lot of room for growth. I will hold it until it multiplies many times.
