For example, suppose that XYZ Corp. had planned to grant stock options for its CEO on May 7, 2007. However, XYZ Corp. is going to release its earnings a week later, on May 14, and it is believed that the earnings will be under guidance. Because the company didn't meet its earnings projections, the share price will likely drop. Moving the option-granting date to May 15 is likely to cause the option's strike price to be lower compared to if the grant date had been on May 7.
This practice is fairly controversial, as some feel that bullet dodging may be a form of insider trading because the option holder, who is usually a member of the company's management, will benefit by using information that is not available to the public.
