I have an acquaintance who does a significant amount of options trading. He'd bought options on PUMA Biotech based on conversations he'd had with a local Starbucks Barista (the barista had asked him about it, and he'd looked into PUMA). He told the barista to buy what he could. Within two weeks it jumped significantly. It was July 2014 when this occurred.
Check the stock history here (expand to 3-year view and check out the jump in July 2014): http://www.marketwatch.com/investing/stock/PBYI
He went and bought a brand new BMW M4 with the proceeds.
The barista had purchased enough to make the stock jump that much? What was this, a barista by hobby who was a secret billionaire?
