Lead: The spot/three-month discount has gradually narrowed, and it is expected that short-term decline will be more likely, but consumer buying will support prices. Zinc: Short-term profit-taking pressure. Tin: Traders are buying aggressively, and they can build more than one position under $7,250. Nickel: The support at $14,500 is strong, but if it closes below this point, the next support level is $13,500. Source: China International Futures Brokerage Co., Ltd.
