For example, let's say you purchase a Tom Brady long APT at the beginning of the season. Brady then proceeds to have an amazing season consisting of 100 touchdowns and another Super Bowl title, generating above-average performance statistics. This would cause his long APT price to increase, creating a positive return on your investment. On the other hand, if Brady endured a bad season and generated below-average statistics, this would cause his long APT price to decrease and a negative return on your investment.
