Anthony Palomba, a researcher and professor at the University of Virginia's Darden School of Business, estimates that the stock gains in the first hour alone after the preorders went live suggest an increase of about $1 billion in revenue.

"Take-Two shares rose almost 3% in early trading when pre-orders opened, and some analysts modeled as much as $1 billion in revenue in the first hour alone," Palomba wrote.

I don't get it. Am I missing something? The stock gains suggest $1 billion in revenue? What does the stock price have to do with pre-orders of the game?
