[SMM Cast Aluminum Alloy Morning Comment: ADC12 Generally Stable with Slight Fall amid Tug-of-War between Sellers and Buyers] Last Friday, the ADC12 market overall operated in a generally stable with slight fall manner. Some enterprises followed with slight declines driven by weakening aluminum prices, while others maintained a wait-and-see stance with stable pricing due to high costs and tight compliant supply. Supply-demand structure perspective, demand side performance remained mediocre, suppressing price rise; however, the supply side saw marginal tightening due to factors such as invoice shortages, import contraction, and phased production cuts, providing certain support for prices. Against this backdrop, ADC12 prices are expected to continue to move sideways in the short term, with relatively limited downside room.

5.18 SMM Cast Aluminum Alloy Morning Comment

Futures: The most-traded aluminum alloy 2607 contract closed at 24,305 yuan/mt overnight, down 55 yuan from the previous trading day, a decline of 0.23%. Short-term SMA lines turned downward, with prices falling below the 5/10/20/40-period moving averages, breaking the short-term bullish trend. The WR indicator was at -84.57, in the oversold zone, indicating that short-term downward momentum had been fully released, with potential for a technical rebound.

Spot-futures price spread daily report: According to SMM data, on May 15, the SMM ADC12 spot price was at a theoretical premium of 535 yuan/mt to the cast aluminum alloy most-traded contract (AD2606) closing price at 10:15.

Warrant daily report: SHFE data showed that on May 15, total registered warrants for cast aluminum alloy were 36,146 mt, an increase of 844 mt from the previous trading day.

Aluminum scrap: A00 aluminum prices fell 240 yuan/mt from the previous trading day yesterday, and aluminum scrap market prices generally followed the decline. Aluminum scrap market is expected to continue fluctuating at highs this week, with shredded aluminum tense scrap (priced based on aluminum content) mainstream range maintained at 20,500-21,300 yuan/mt (tax exclusive). On the supply side, tightening fiscal and tax supervision is unlikely to ease in the short term, and ticket shortages and expectations of reduced imports will continue to provide floor support for aluminum scrap prices, with the market pattern of holders holding prices firm and holding back from selling persisting. On the demand side, off-season effects continued to intensify, with insufficient incremental end-user orders. Secondary aluminum enterprises showed a trend of production cuts, and downstream procurement remained dominated by small-lot just-needed restocking, making concentrated stockpiling actions unlikely. The secondary aluminum market is expected to continue its pattern of weakness in both supply and demand.

Summary: Last Friday, the ADC12 market was generally stable with slight fall overall. Some enterprises followed with slight declines driven by weakening aluminum prices, while others maintained stable prices and a wait-and-see stance due to high costs and tight compliant supply sources. From the supply-demand structure perspective, demand side performance remained mediocre, suppressing price rises; however, the supply side saw marginal tightening due to ticket shortages, import contraction, and phased production cuts, providing certain support for prices. Against this backdrop, ADC12 prices are expected to continue moving sideways in the short term, with relatively limited downside room.
