BA-C.BA is trading 8719% up now at $22930.00, an extreme move from its recent $260 range. Available news and filings show no corporate actions, dividends, splits, or fundamental catalysts that could justify this jump, and prior coverage already flagged the move as a likely data or pricing error. The broader market is only modestly higher, reinforcing that this looks like a quote anomaly rather than a genuine revaluation.
