The Guojun Strategy team released a research report on April 11, pointing out that the Shanghai Composite Index reached a new high in nearly one month this week, but it is still "short of breath" from 3500. It is difficult to describe the trend market in this round of rebound, and it is still a volatile pattern in the short term. Considering that April is the time when the quarterly report has the greatest impact on the stock price, it is the opportunity to seize the decisive victory of the quarterly report. Through the profit forecast changes to the quarterly report forward, iron and steel, coal, non-ferrous, banking, chemical industry profit increase probability is higher. The quarterly report is only the starting point, and looking back at the export chain, consumer services, manufacturing investment and even the real estate chain are worthy of continuous attention.
