Trend analysis

Today, the three major A-share indices collectively opened higher. The GEM index led the increase, and growth directions such as pharmaceuticals, biology, and communications showed active performance. Overnight, the overall strengthening of US stocks and falling oil prices provided a positive catalyst for market sentiment, and policy signals such as revisions to domestic integrated circuit protection regulations and plans for new power systems continued to be released. Yao Ming Kangde raised its annual performance guidelines and intensive repurchases by several companies to reflect industrial capital's approval of the current valuation.

In the short term, the technology sector showed signs of a sharp rebound after experiencing sharp adjustments in the early stages, leading the way in communications, computers, etc., but there is still internal differentiation in electronics and semiconductors. Pharmaceutical Biotech performed well under the catalyst of CXO performance, and the medical service sector rose more than 6% in a single day. There was a return in profits in the direction of high dividends such as banks and coal, and the market style was rebalanced from early defense to growth. The institutional consensus bias is that A-shares may enter the recovery stage in August, and industries with improved performance and improved supply and demand patterns are expected to receive financial attention, but the overall market is still in a period of turbulence and consolidation. Styles are rotating rapidly, and attention should be paid to trading volume coordination.
