the 1 Share (why it's important)
When a fund already owns 1 share or more in a company/shell they means that it has been reviewed by their compliance officers and approved (share ownership) to be added into their portfolio.
When there is a major event, merger or other the Fund can simply buy more without further compliance review. Review can take weeks in some cases, and in that time prices would have already skyrocketed ...
That means this stock is on the radar of one or more Major Funds, waiting for an event, same as we are...
