Most of the 144 filings our very simple.
First, people have to keep the 144 current IF they want to sell their restricted shares.
Second, people must file a 144 and other paperwork to remove the restriction on their shares. I just did that today and filed a 144 that should be processed soon, but I am long and not selling in the near future.
A lot of the initial shares were restricted for one year. Now most of them have passed that timeframe and need to be filed under a 144 to BE ABLE to sell. I think if you look at the trades, these people aren't really selling much of anything.
I am new to this game, but this is what I understand from my broker and posters here.
