Form 144 Sales.
I held some restricted stock in another company for several years. After 1 year, I was able to file a form 144, IN CASE I wanted to sell shares, with a restricted legend, in the following 3-4 months. After that, if I still held the shares, I had to file another form 144 again, to open another 3-4 month window.
After the 2 year mark, I had the option of sending the certificates to the transfer agent, and having them re-issued, without the restrictive legend. Then I was able to deposit them in my trading account, and trade normally.
So, many of the form 144 filings are people expecting they might want to sell soon. If there is a price reset, who wouldn't ??
