Core Viewpoints of the Report - Last week, the stock index futures continued to fluctuate upwards, but market differentiation intensified, showing the characteristic of "strong index, weak stocks". The core contradiction lies in the game between policy expectations and economic reality. The market presents a game feature of "policy support" and "fundamental pressure", and it is necessary to focus on the matching degree between policy implementation efficiency and marginal improvement of economic data. Maintain optimism in the medium - long term, but be vigilant against short - term fluctuations caused by repeated expectations of peripheral liquidity [31] 3.
