1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - A-share market continued to rebound this week with an oscillating upward trend. The growth style performed well, driving up TMT-themed funds. However, many quantitative index-enhanced products still had mediocre excess returns. The weekly average daily trading volume of the two markets decreased by 10.63% week-on-week. If the trading volume continues to shrink, the chips in high-position sectors will loosen and differentiate, and the market will shift from a unilateral rise to a range-bound pattern. It is recommended to focus on the supplementary rise opportunities of low-position sectors. The basis of four types of stock index futures contracts showed differentiation, with the IM contract having a large discount and the IF contract having a large premium. In the upcoming week with a dense schedule of important macroeconomic events, the A-share market is likely to maintain a volatile and relatively strong market. It is recommended to focus on technology frontier tracks such as robotics and AI computing power, and also seize the rotation and supplementary rise opportunities of sectors such as securities, pig cycles, and games. After a deep adjustment, the national debt market has shown rare allocation value, and investors are advised to moderately increase the allocation ratio [1][11][16]. 3.
