Brazil ETF EWZ Opens Up 12%

A 12% opening move in a single-country ETF is the kind of gap that reflects a repricing of country risk rather than ordinary trading flow, and it lands on a fund whose holdings are heavily weighted toward Brazilian large caps, so the effect is broad rather than sector-specific. The open question is whether the gain holds through the session or fades, since opening gaps of this size often reflect thin pre-market liquidity or a one-off catalyst that the item does not identify.
