Adidas shares plunge 18% in worst-ever single day after weak Q2 results

Adidas shares fell 18% on the Frankfurt Stock Exchange in a single session — the steepest one-day drop in the company's history. The sell-off was triggered by disappointing second-quarter results: operating profit came in at €574m, well below the analyst consensus of €616m, leaving the stock down roughly 10% year-to-date.
