Skippers take. News broke late Thursday and many needed funds so they sold their XXXX stock to buy BMSN. It takes 3 days for the shares to be "settled" so those who sold their XXXX stocks on late Thursday and Friday, wont have funds cleared until after the "settlement" of 3 days, in which I suspect huge buying on Tuesday, Wednesday and an epic run on Thursday. This is where Gilligan is a little "grey" The X date is March 18th So, In my opinion, a shareholder has to have his/her shares "settled" by the 18th; Friday 14th being the last day to get the divy.
Anyone who has purchased a home or property knows the closing date. All the monies have to be "settled" by the closing date. If not, no key, no deed.
