HSX, or the Hollywood Stock Exchange is my online game of choice at the moment.

The best money is generally made by predicting the box office takings of a certain movie and then buying or shorting your shares depending on whether or not you think the share price will go up or down due to it's actual box office.

In the last two weeks I've done pretty well out of this with my predictions regarding 'Man On Fire', 'Mean Girls' and 'Van Helsing'. This weeks punt is on the Brad Pitt blockbuster 'Troy'. My guess it that it will open on the weekend with a total of around $67 million. This estimate is based on my prediction that 'Troy' will be bigger than 'Van Helsing' which ended up doing $57 million.

I guess I'll have to wait until Monday to see if this has paid out!!
