Mornings like we had on Wednesday are exactly why I get up and do this show every single day the market is open.

UniQure NV (QURE) opened around $43. Touched $48.88 intraday. Closed in the high $47s. Previous close: $26.99. An 81% gain, overnight.

Read that last number again. This stock nearly doubled in a single session.

Now, I could just tell you “wow, what a move” and carry on with my day. But that’s not what I do, and it’s not why you’re reading this. Right here I want to walk you through exactly what happened, why it happened, and — more importantly — why I had already positioned for it eight days before the rest of the market noticed.
