1. Report Industry Investment Rating - No information provided in the report 2. Core Viewpoints - For the black - series commodities, affected by the sharp rise in the Middle - East tensions and the subsequent increase in crude oil prices, the prices of black - series commodities are expected to be short - term strong. The overall supply and demand in the market are recovering, with both increasing production and demand, but the inventory is still rising, and the market's demand expectation for this year is relatively weak, with a pessimistic view of the fundamentals. Technically, the futures prices have broken through the resistance of the middle track of the Bollinger Bands, and the probability of short - term strong oscillation is high. For both steel products (thread and hot - rolled coil) and iron ore, the operation suggestion is to hold long - position orders lightly and adopt a strong - oscillation mindset [2][4] 3.
