There has been plenty written about the "Guitar Hero Curse," since the latest ad features both Alex Rodriguez and Michael Phelps in it.
That has some saying that the other two athletes in the spot, Kobe Bryant and Tony Hawk, better watch their backs.
But how about the company that makes the game?
"Guitar Hero" might be the hottest franchise in the world, but the game's maker Activision Blizzard yesterday announced a $72 million loss for the fourth quarter.
By 10 a.m. ET this morning, the stock was down 5.4 percent to 8.97, just 83 cents off its 52-week low.
Shares reached an all-time high close of $18.62 on July 18th of last year.
