Corteva shares were selling off yesterday as the market adjusted to the company's completion of its spin-off of the seed and genetics business into a new entity called Vylor. While the stock appeared to crash by roughly 85% due to the structural separation and subsequent index reshuffling, the market is now recalibrating the valuation of the remaining pure-play crop protection company. Investors are also monitoring reports of a potential lawsuit that could impact the terms of the split, adding a layer of uncertainty to the post-spinoff transition.
