Industrial Securities: The valuation of insurance stocks is in a relatively reasonable position. The Industrial Securities Research Report pointed out that we should continue to be optimistic about the insurance sector and focus on the targets with better performance stability and stronger dividend insurance sales ability. At present, the valuation of insurance stocks is in a relatively reasonable position, but as a strong beta plate, if the equity market further picks up, it may also perform well. There are three catalytic points for the further opening of the subsequent valuation space: first, the long-term interest rate and the performance of the equity market; Second, the adjustment and optimization process of the asset structure of insurance enterprises; The third is the sales situation of dividend insurance. In particular, dividend insurance sales may exceed expectations, and if verified, it will become an important support for opening up the repair space of insurance valuation.

Guosheng Securities Research Report pointed out that AEC(Active Electrical Cable) is an active cable interconnection scheme, which is mainly used in short-distance high-speed data transmission scenarios in data centers. 1)AEC is expected to become the first step for optical module manufacturers to penetrate downwards. Optical modules need to master photoelectric conversion and high-speed data communication, and DAC/AEC/AOC products have relatively mature technical requirements compared with single-mode/multimode optical module products with longer transmission distance. 2) Copper interconnection is widely used by large CSP not only in NVIDIA. NVIDIA used a large number of high-density copper interconnects in B series products, which made the industry re-recognize the reliability and price advantage of copper interconnects in short-distance scenes. 3) In the era of Lian Heng, domestic manufacturers still have obvious advantages. Chip manufacturers, represented by NVIDIA, have been hoping to conduct a comprehensive industry consolidation and provide customers with a complete set of solutions. What CSP manufacturers want more is the decoupling of the industrial chain, and every link such as GPU, copper connection, optical module and switch can find corresponding suppliers. The heavy volume of AEC and the rise of CSP manufacturer's independent scheme indicate that the computing power industry chain has entered the era of Lian Heng, and we are firmly optimistic about the domestic related computing power industry chain.
