Market makers have special exemptions from the rules: they are allowed to carry a naked short for up to twenty–one trading days before they have to borrow a share. When the share is not borrowed in the allotted time and a buy–in does not occur, and they rarely do, the naked short becomes a fail–to–deliver (of the borrowed share).
There is nutting false here. I am not sure how many companies you have started up, managed, listed and made them a very successful venture for all involved. We have legal obligations etc, there is lots I would like to say but we have to wait. If you don’t believe, don’t buy !!
