Core Conclusions - The overall valuation of A-shares has expanded this week, with the steel industry leading the gains. The weak accumulation of winter storage for steel this year has resulted in lower inventory pressure, and the seasonal increase in steel demand post-holiday, combined with strong price recovery expectations due to PPI rebound, supports a rebound in the steel sector. The current full dynamic valuation of the steel industry is at the historical 45.3 percentile, indicating further room for valuation improvement [1][8].
