Siquan New Materials (301489): Core supplier of heat dissipation solutions for TPU chips, with ultra-thin VC uniform heat plates only 0.25mm thick, improving heat dissipation efficiency by over 30% compared to the industry average.
Can we continue? Let’s see tomorrow; it’s a bit difficult. Without exceeding expectations, funds will be cautious.
The market rebounded for the third day; the strong applications from the previous two days diverged. The previously strong technology sector saw a rebound today, with Zhongji Xuchuang reaching a new high. It seems like everyone is benefiting. If this rebound holds, should we pull up others as well? This time, I didn’t fully invest at the first opportunity; I captured applications, and the ice point is one of the stocks, Yidian TX, and I also bought Lang C Xin X (this stock is not strong enough, making it very difficult to trade, and I didn’t catch the rhythm well). This is the first time I clearly made a node; I have some ideas now. However, my courage is not enough; I also added to my index fund investment, waiting to take some profits from the rebound. Today, I sold half of my position in 010238.
Can you understand why I sold?
How will the market perform today? It’s unclear, so let’s wait. If I see a bull market, I might increase my application positions. Alibaba’s Qianwen concept stocks are below. Here are the fund articles I wrote earlier. My funds.
