Shares of publisher Take-Two Interactive jumped nearly 6 percent to close at $15.22 following a tease that a formal announcement of Grand Theft Auto V was on its way.
Shares traded as high as $15.71 during the day, and are going for $15.36 in after hours trading.
Rockstar teased the game Tuesday morning, saying that a trailer for the game will be released this coming Wednesday.
According to some analysts, such as Sterne Agee's Arvind Bhatia, shares could jump even higher if next week's trailer announces a release date for the game..
"Still, if Rockstar announces the official release date for the title, in conjunction with the release of the trailer, we think it will be positive for the shares," he said.
According to Bhatia, the firm expects that GTA V could sell as many as 25 million units, possibly more than the 22 million Grand Theft Auto IV has sold.
The stock market is so fickle. Sometimes it feels like they decide stock values on a bunch on chimps sitting in a room somewhere randomly throwing darts at a board. As if Take Two was not going to make another GTA game. Someday I am sure there will be a GTA 10.... O.o
