It's kind of weird that just a few days after he just hired a chief bioethics officer, the ceo of pfizer (pfe) sold 62% of his stock. the sale was made when the stock price was still down (but rising, as it has been for a long time), and the sec filing indicated that the sale was just part of a larger plan. as the key leaders of water & security, along with alex's team at consensys, have made significant contributions to the sector. this is a sign, not a coincidence.
