AMD's stock is wild. It was around $2 just a few years ago and has been on a non-stop trend up to almost $60 today.
Wild is to put it mildly, the stock is historically extremely volatile. If past performance predicts anything, it could potentially tank in the next couple of years, like it did the last few times it shot up. Obviously they are doing some great work, but I wouldn't go all in on them for the long haul.
