BOC International: Welcoming Year-End Recovery Market The market is about to enter a year-end configuration phase. Starting this week, the market will enter a phase with a lack of policies and data, and is likely to enter a year-end market configuration period. This week, the value style of the market has shown a clear recovery, which mainly comes from the fact that the short-term small-cap style trading congestion is high, and the short-term advantage of small-cap styles comes from market expectations for policies and active short-term trading funds. In the short term, the large and small-cap styles face a rebalancing process, but until domestic demand data stabilizes, the trend of the large-cap market dominance has not yet formed, and the market structure will continue to favor small-cap stocks and strong thematic trends.

Galaxy Securities: Valuation of the Chemical Industry Expected to Gradually Recover Galaxy Securities' research report pointed out that at the current point in time, the valuation of the chemical industry is at a low level that has not been seen since 2014, and it has medium to long-term value for investment. Recently, a series of policy favorable measures have been introduced, and macroeconomic expectations are expected to improve, bolstering investor confidence and gradually restoring the valuation of the chemical industry. Due to the dual pressures of supply and demand, most chemical products have performed weakly in price differentials this year. Currently, there are still many ongoing projects in the chemical industry, and with the gradual realization of policy stimulus effects, the end consumption of chemical products may improve to a certain extent, but it is expected that there will still be time needed to digest existing and ongoing production capacity.
