1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - Consumption building materials have raised prices intensively, and the price transmission has entered the implementation stage. The profitability of leading companies is expected to gradually recover due to the clear pattern of consumption building materials and price - increasing opportunities provided by raw material price hikes [2][7] - After the release of the "15th Five - Year Plan Outline," attention should be paid to the capacity optimization of traditional building materials such as cement, glass, and fiberglass under anti - involution, as well as advanced new materials such as high - end electronic cloth fiberglass and heat - resistant ceramics [5][8] - The AI chain has a high prosperity and an obvious price - increasing trend. The fiberglass field is relatively favored, with electronic cloth entering the price - increasing cycle and roving having a good outlook in the first half of the year. Waterproofing in the second - hand housing transaction and new construction segments is also relatively favored. It is expected that the overall construction demand in 2026 may be similar to that in 2025, and more attention should be paid to individual stock opportunities in segmented fields. Commercial aerospace is in the stage from 0 to 1, with many domestic and foreign catalysts this year, and it still has a high long - term allocation value [5][8] 3.
