Rainbow shares's huge losses are mainly related to its main business. Its color kinescope has completely lost its market competitiveness. At present, flat panel liquid crystal displays are used in televisions and computers. Although a lot of money has been invested in transforming old equipment in recent years, its high cost makes it difficult to make a profit. If the company's main business does not change, it is certain to continue to suffer huge losses.
If you are deeply involved, the company still has some hope. The reason is that Rainbow Group was transferred to China Electronic Information Industry Group Co., Ltd. for free, and China Electronics will indirectly control 34.42% of the shares of rainbow shares and become the new controller of rainbow shares. China Electronics may reorganize rainbow shares.
