Corteva ( $CTVA) Drops -86% in 30 Days Following Vylor Spinoff (See the latest news for any ticker on Tickeron.) Corteva's roughly 86% 30-day decline is a mechanical result of its October 1, 2026 spinoff of the seed and genetics business into Vylor, not a comparable loss of shareholder value. Shareholders of record on September 24, 2026 received one share of Vylor (VYLR) for each Corteva share held, shifting most of the company's former market value into the new entity. Corteva now operates as a focused, pure-play crop protection company spanning herbicides, insecticides, fungicides, and biologicals. $MOS $CF $IPI $NTR
