- **Tracking indicators and calculation methods** The report uses two key metrics: the proportion of large buy order transaction amounts and the proportion of net active buy transaction amounts. The large buy order transaction amount proportion reflects the buying behavior of large funds. It is calculated by restoring tick-by-tick transaction data into buy and sell order data based on bid and ask sequence numbers, filtering for large orders by transaction volume, and computing the proportion of large buy order transaction amounts relative to the total daily transaction amount. The net active buy transaction amount proportion reflects investors' active buying behavior. It is calculated by identifying whether each transaction is an active buy or sell based on tick-by-tick transaction data, subtracting active sell transaction amounts from active buy transaction amounts, and computing the proportion of net active buy transaction amounts relative to the total daily transaction amount[7] - **Individual stock tracking** The report tracks individual stocks based on the two metrics mentioned above. For the past 5 trading days (20260323-20260327), the top 10 stocks with the highest average proportion of large buy order transaction amounts include New Energy Taishan (93.2%), Snow Wave Environment (85.7%), and Zhongli Group (85.4%). Similarly, the top 10 stocks with the highest average proportion of net active buy transaction amounts include Zhen De Medical (16.7%), China General Nuclear (15.9%), and Zhejiang Energy Power (12.6%)[9][10] - **Broad-based index tracking** The report applies the same metrics to major broad-based indices. For the past 5 trading days, the average proportion of large buy order transaction amounts for indices such as the Shanghai Composite Index, SSE 50, and CSI 300 ranged from 69.5% to 73.7%. The average proportion of net active buy transaction amounts for these indices ranged from 1.0% to 3.2%[12] - **Sector tracking** The report tracks the metrics across various sectors based on the CITIC primary industry classification. For the past 5 trading days, sectors such as coal (78.4%), steel (78.7%), and real estate (78.9%) had high proportions of large buy order transaction amounts. Sectors like medicine (12.3%), steel (10.8%), and food & beverage (10.6%) had high proportions of net active buy transaction amounts[13] - **ETF tracking** The report tracks ETFs using the same metrics. For the past 5 trading days, the top 10 ETFs with the highest average proportion of large buy order transaction amounts include Guotai CSI A500 ETF (92.4%), Huatai-PineBridge CSI A500 ETF (92.1%), and Penghua CSI Oil & Gas ETF (91.3%). The top 10 ETFs with the highest average proportion of net active buy transaction amounts include Haifutong SSE Urban Investment Bond ETF (24.4%), Fuguo ChiNext Artificial Intelligence ETF (19.4%), and Guotai SSE 10-Year Treasury Bond ETF (16.9%)[15][16]

Report Industry Investment Rating - The investment rating for the steel industry is "Positive" [2] Core Viewpoints of the Report - The steel industry is expected to see long - term improvement in supply - demand relations during the 15th Five - Year Plan period. In the short term, iron ore prices are expected to be strong due to factors such as the Iran situation and tightened iron ore procurement restrictions, strengthening the cost support for steel prices. With the long - term improvement in the supply - demand pattern, strengthened short - term cost support, and low sector valuation, the steel sector is expected to experience value restoration and has significant allocation value [3]. - Based on the judgment of the steel industry cycle, in an environment where PPI is at the bottom of the cycle, market liquidity is abundant, and risk premium is rising, the steel sector has strong "anti - involution" attributes and a large profit restoration space. High - quality steel enterprises have excellent upward elasticity from performance restoration and room for sector valuation increase from the improvement of the supply pattern. The industry still has medium - to long - term strategic investment opportunities, so the "Positive" rating for the industry is maintained [3]. Summary by Directory 1.
