Before May 6th, the stock position was Man Cang, and there was financing. The industry with heavy positions is the whole chicken industry. At the time of clearance, basically all positions are at a low level. Now it seems to have gone up. If you hold it, you have earned a lot. Low clearance is a big loss. However, the income after switching to futures is ok, so if there is not much change in the later period, it is still partial futures. Moreover, there is plenty of time now, unlike the previous stock trading, which depends on a lot of things to study listed companies. Generally speaking, futures are relatively simple, and it is basically enough to understand inventory, supply and demand, and production cycle.
