A-share market is an early market with a history of 30 to 40 years. Anyway, it is still quite early, and the mechanism of this market itself is relatively perfect. Companies that can really appear in this market are strictly examined. This is an established company, but the more established the company is, the easier it is to decline. After all, the market is changing rapidly, and the stocks of some companies in a market are very popular. For example, the famous liquor sector is the new energy sector and the semiconductor sector, which are very popular in both the A-share market and the Hong Kong stock market, but other sunset industries other than these hot sectors are not very popular.
Nearly half of the A-share market is junk stock, which means that its changes are meaningless, there is no big change, and it is very stable, which has no impact on your investment. If you buy this, you will lose money or you won't make much money. In fact, buying stocks is not that risky. Of course, I want to make more money, so I won't consider it when it reaches about 50%, and 10%~20%. What you bought now is only half a year. You may double or even higher directly, but you may also lose money. Therefore, the real high-quality stocks with proven prospects and long-term development benefits average around 30%.
To improve the performance of listed companies, of course, is to increase revenue by cutting costs. These are two main ideas, because what you do to promote the company is to control your cost. If you reduce three expenses, your operating costs will naturally be lower. In the end, your profit will be higher under the same circumstances, and then the other direction is to improve sales performance. What kind of business you want to sell, you must have external contacts, no matter what services you sell.
