I want to invest some money in the stock market in the second half of this year, about 4000 yuan. What stock should I buy? When is the best time to enter? I am a sophomore.

You can do it now. After 2300, it is a safer area. Countries in this region have made a lot of concessions, which is the bottom of the policy at present. The investment of 4000 yuan is not large. I suggest buying some low-priced stocks and buying CNOOC Engineering. The price of this stock is low, and CNOOC is now entering the deep water market. At present, China has its own deep-water pipe-laying vessel and jacket construction base. The workload this year and next is very full. There is also a lot of policy support within the company system, which will have a good performance in the coming year. Because you are a student, you have no time to watch the disc, so I suggest you do the medium and long term.
