Could be simple betting on Zen being great, AMD making deals indicating its not a lifeless corpse, a Polaris launch that while enthusiasts do not like, investors are hopeful that gives next quarter financials a boost, Radeon Technology Group existing, AMD getting Samsung to make chips, instead of relying on TSMC or GlobalFoundries. Perhaps after getting boosted from a penny stock, the bandwagon is getting larger, everyone hoping for that quick skyhigh rise to glory for AMD (and their stock) is finally here.
Am i missing anything? Oh, and those persistent rumors that AMD is about to be acquired.
Newest rumor-ish? http://www.bizjournals.com/austin/news/2016/07/25/amd-stock-jump-fuels-acquisition-speculation.html
