Since China Merchants Securities resumed trading in 2015, it was found that the sharp decline was mostly caused by external shocks or liquidity risks, and the stabilization was marked by policy responses. The adjusted average rebound window is 34 trading days. Wandequan A's average rebound rate exceeds 19%, and the larger the decline in the early period, the higher the room for a rebound in the later stages. The industry's performance rotated in a “two-stage” pattern: in the first 10 trading days of the rebound, high-beta and ultra-low sectors such as electronics and computers, led the way; after 20-60 trading days, the market moved to the main line supported by the boom, such as power equipment, food and beverage. In response to this round of the market, it is recommended to allocate in two steps: initially prioritize high-elasticity sectors such as TMT; return to economic balance after 10-20 trading days, and focus on power equipment, chemicals, pharmaceuticals, coal and non-bank finance. The track focuses on seizing opportunities to make up for increases in overseas computing power price chains, the flexibility of domestic computing power hardware, and the safe-haven and rebalance value of gold. The overall layout revolves around the three main lines of “technological innovation, enterprise going overseas, and rebalancing traditional undervaluation”.
