This is attributed to changes in market risk appetite as some investors choose to take profits ahead of an upcoming military parade [4] - Brokerage stocks weakened, with Dongfang Caifu and Tianfeng Securities leading the decline due to a reform in fee structures. A report indicates that the reduction in management fees for public funds and trading commissions has led to a 37% decrease in brokerage firms' income from brokerage services in the first half of the year [4] Investment Strategy - The current market is transitioning from being driven by capital to being driven by performance, with a trading volume of 2.5 trillion indicating a shift in main capital towards sectors like CPO, liquor, and integrated die-casting, which remain the primary focus [5] - Caution is advised for sectors that have seen significant short-term gains, as they may experience volatility, while sectors like military and brokerage that have undergone sufficient adjustments may present new opportunities for investment [5]
