Blockbuster Warrants allow traders to participate in the long-term box office success of the biggest movies year-round. Make the call on which movie you think will make its strike price during its first 12 weekends at the box office and profit from your prediction.
If a particular film makes the strike price by its 12th weekend, then the warrant will cash out at the difference between the actual box office and the strike price. If the film does not hit the strike price, then the warrant will cash out at zero. The Blockbuster Warrant will cash out after its 12th weekend of release.
