China Securities Co.Ltd(601066) strategy analyst Chen Guo said that the medium-term perspective continues to maintain the judgment that A-Shares are building a U-shaped bottom area. On the one hand, the policy bottom and credit bottom may have been roughly confirmed, and the subsequent profit bottom will be gradually completed in the medium term; On the other hand, the market valuation and sentiment indicators have also entered the bottom area of the market. Although there is still the possibility of continued decline in the follow-up, the space in terms of odds is relatively limited. Therefore, from the medium-term perspective, although the market bottom grinding process may continue to repeat, investors do not need to be too pessimistic and should patiently wait for the market to complete the construction of U-shaped bottom.
