Hey Sicon, from talking to my Attorney today this is what I found out.
It really means nothing for the shareholders or the companies involved, the restriction prohibits the listed companies from selling any shares to anyone.
It also stops the transfer from broker to broker.
IE, If I have GRDO shares in my TDA account and I want them moved to my Scotturd account, now I can't do it because of the restriction. But the MM's can trade between themselves all day long.
It's really no big deal for the companies, especially if the company is already maxed out with their shares.
