The term "naked option" refers to an options trading strategy where the seller of the option does not own or have a position in the underlying security. This strategy brings an increased level of risk to the seller as they are exposed to potential unlimited losses. Some synonyms for the term "naked option" include "uncovered option," "unprotected option," "bare option," or "unhedged option." These terms all refer to the same concept of selling an option without any underlying holding or risk protection. It is important to understand the risks associated with naked options and to thoroughly research and understand any options trading strategy before implementing it.
