[Citic Construction Investment Chen Guo: the volatility center of A shares is expected to move up in the second half of the year. Revaluation of value stocks and technology stocks are still the main line]. Chen Guo, chief strategist at Citic Construction Investment Securities, said on May 10 that he maintained the judgment of slow economic recovery in the second half of the year and expected that the volatility center of the A share market would move upward. In terms of configuration, Chen Guo believes that in the second half of the year, we should focus on the media, computer, communications, semiconductors, traditional Chinese medicine, non-bank finance, construction and other seven major industries, while the theme should focus on AI (artificial intelligence) / digital economy and special valuation (valuation system with Chinese characteristics). Chen Guo believes that this year is the beginning of a long bull, a local cow, and a slow transition to an all-round cow. If there is no significant change in the macro variables in the second half of the year, the structural clues mainly lie in the revaluation of value stocks and the grasp of opportunities for science and technology stocks, but they all need to further deepen the optimization around the marginal changes in fundamentals, and as a whole, the top increase is mainly from the latter.
