Event summary

The Sprott Junior Copper Miners ETF (COPJ) experienced an 11% single-day drop, causing concern among investors, despite a 93% return over the prior twelve months. This significant decline was attributed primarily to Broadcom's lighter Q3 AI revenue guidance, which raised questions about the pace of hyperscaler data center buildouts, a key demand driver for copper. The article suggests that cautious hyperscaler capital expenditure commentary could lead to a repricing of the AI demand premium in junior miner valuations.
