What do you mean by "first time in history"? This will not be the highest percentage gain in the history of the stock. Leaving aside meaninglessly large percentage gains when the stock was below $5 a share, the largest percentage gain (and absolute gain in points) was October 26, 2007, when it gained 31.11 points, which was a percentage gain of 27.5 percent. Even so, today promises to be the largest gain since then. And I am not complaining!!!
