Investment Rating - The report maintains an "Outperform" rating for the construction and building materials sector, indicating expected performance above the market index by over 10% [5][79]. Core Views - The construction and building materials sector is expected to benefit from two main themes: "infrastructure recovery" and "anti-involution," leading to significant excess returns in recent times. The Ministry of Industry and Information Technology announced a new round of growth stabilization plans for key industries, including construction materials, which is anticipated to boost infrastructure investment and order recovery in the construction sector [1][3]. - The building materials sector is experiencing a structural improvement in supply and demand, driven by the "anti-involution" trend and expectations of stable growth, which are expected to resonate positively across various sub-sectors [1][3]. Summary by Sections Cement - National cement prices fell by 0.9% last week, with declines of 10-30 yuan/ton in regions like Jilin and Hunan. High temperatures and rainfall have weakened construction demand, leading to a drop in the average shipment rate to 43%. The sector faces significant inventory pressure and ongoing price declines [2][23]. Glass - The domestic float glass market showed signs of recovery, with prices increasing due to speculative demand and replenishment from downstream buyers. Inventory levels have decreased, alleviating some pressure in certain regions. The photovoltaic glass market also saw improved trading conditions, with a slight reduction in inventory [2][41]. Fiberglass - The price of non-alkali roving remained stable, while electronic yarn prices showed slight increases. The overall market demand remains weak, with transactions primarily based on need [2][47]. Investment Recommendations - The report suggests focusing on leading companies in the cement and glass sectors, such as Conch Cement, Huaxin Cement, and Qibin Group, as well as companies benefiting from structural demand in fiberglass, like China National Materials and China Jushi. The construction sector is expected to recover in the second half of the year, with recommendations for companies like China Railway Construction and China Communications Construction [3][12].
