zombie(redirected from Denial of service attack)
Also found in: Dictionary, Thesaurus, Medical, Legal, Encyclopedia.
A publicly-traded company that continues operations despite a merger or bankruptcy. Stocks in zombies are usually low in price because the companies are likely to cease operations (and the stocks will consequently become worthless). However, a few bottom feeders may be interested in a zombie if they believe that it can restructure and become profitable.
A company that remains in business even though it is technically bankrupt and almost surely headed for the graveyard.
