Could have made a huge killing on GoPro
 

From CNN today

GoPro (GPRO) is continuing its adrenaline rush ever since its IPO. The stock spiked about 22% Tuesday, and is now more than double its initial public offering price from last week. It wasn't clear what was driving shares so much higher, but Charlie Anderson, an analyst with Dougherty & Co., noted that the company only sold about 18 million of its 123 million shares outstanding during the offering, and therefore investors who didn't get a piece of the offering before the IPO were forced to buy it once it started trading.

Oh well, as the S&P goes up and up I'll retire sooner!
