Why is Ero Copper Corp. (ERO) stock moving?

Ero Copper's recent news is positive. Its Q3 2026 results beat estimates, with adjusted EPS of $1.22 against $1.15 expected and sales of $348.0M against $346.15M. Scotiabank then upgraded the stock to Sector Outperform on Nov 3, while trimming its price target to 53 from 55. The shares rose 4.4% that day to 30.44 on heavier trading. Price action since then has been volatile and not clearly one-directional. The stock fell 8.9% on Nov 5 to 28.09 on 2.94M shares, the highest volume in the 30-day window, and no news item in the set explains that drop. It recovered 8.5% to 31.32 on Nov 9 and closed at 30.67 on Nov 10, with VWAP near 30.52. Over the 30 trading days the stock traded between 28.09 and 32.52. Earnings and the upgrade support the fundamental case, but the unexplained selloff and the sideways trading argue for caution in the near term.
