Might pull up a 2 year chart first... "...I bought this stock...a few years ago and sold...how I wish I held strong !!...I think I'm hammer this one! Is been going up and up!!..." "...Could it be the company was doing a buyback and did not announce it?..." A restructuring, definitely not a "buy-back"... If you had held for the two years, almost all your money would be gone.
