Investopedia explains 'Gun Jumping'
The theory behind gun jumping is that investors should make decisions based on the full disclosure in the prospectus, not on the information disseminated by the company that has not been approved by the SEC. If a company is found guilty of "jumping the gun", the IPO will be delayed.
