Group 1: Industry Overview - The supply rigidity of industrial metals such as copper and aluminum has become evident after the capital expenditure contraction and inventory destocking from 2022 to 2024, while three demand engines—AI computing infrastructure, global grid transformation, and new energy installations—are accelerating simultaneously [1] - The non-ferrous metal sector is currently at a dual driving node of "supply-demand mismatch" and "monetary credit reconstruction," transitioning from "cost support" to "demand pull" [1] Group 2: Fund Structure and Features - The C share class of public funds has emerged as a significant tool for asset allocation, differing from traditional A shares by offering "no subscription fee + daily calculated sales service fee," optimizing cost efficiency for specific investment scenarios [1] - C shares have a linear relationship between holding costs and holding time, contrasting with the tiered decreasing model of A shares, making them particularly suitable for investors with high liquidity requirements or short-term market cycle judgments [2] Group 3: Cost Comparison and Flexibility - For example, with a purchase amount of 100,000 yuan, the A share incurs a subscription fee of 1.0%, resulting in a cost of 1,000 yuan regardless of whether held for 3 months or 3 years, while the C share's annual sales fee of 0.4% results in a cost of only 200 yuan for a six-month holding period [2] - C shares allow for quick entry and exit without redemption fee penalties after holding for 7 or 30 days, unlike many A shares that require a holding period of 2 years to waive redemption fees, making C shares advantageous in volatile markets [4] Group 4: Performance and Strategy - The non-ferrous metal sector is known for its "king of cycles" status, characterized by significant price volatility and strong phase-based trends, aligning well with the C share's "low threshold, high liquidity, daily pricing" mechanism [5] - The ETF covering the non-ferrous metal sector is expected to benefit from a "super cycle," with a significant weight in copper (34.2%) and aluminum (14.6%), indicating a robust structure for capitalizing on industrial metal bull markets [7] - The C share of the ETF has shown a remarkable return rate of 171.24% over the past two years, outperforming major indices like the CSI 300, with a Sharpe ratio of 1.73, indicating effective risk-return management [7]
