Filing Notice With the SEC. At the time you place your order, you must file a notice with the SEC on Form 144 if the sale involves more than 500 shares or the aggregate dollar amount is greater than $10,000 in any three-month period. The sale must take place within three months of filing the Form and, if the securities have not been sold, you must file an amended notice.
So I guess we wait to see if there are ammended notices published. I doubt very much we will see any.
Good stocks are obvious. Extensive DD is how you convince yourself to buy a bad one.
