What is Uncovered Put?

A short put option position in which the writer does not have a corresponding short stock position or has not deposited, in a cash account, cash or cash equivalents equal to the exercise value of the put. The writer has pledged to buy the asset at a certain price if the buyer of the option chooses to exercise it. Uncovered put options limit the writer's risk to the value of the stock (adjusted for premium received.) Also called "naked" puts.
