3. Opinion of investment adviser:
The main market indexes were adjusted in a narrow range on the short and medium term moving average, and the individual stock market recovered slightly. The Shanghai Stock Exchange Index has slightly increased its volume compared with Tuesday, but the increment is not enough. When the turnover of the two markets is less than trillion yuan, it is temporarily unable to promote the market to continue to rebound. Therefore, the market as a whole continues to shake and rest, waiting for the turnover to rise.
