Naked short selling

Many issuers and investors have complained about alleged "naked short selling," especially in thinly-capitalized securities trading over-the-counter. Naked short selling is selling short without borrowing the necessary securities to make delivery, thus potentially resulting in a "fail to deliver" securities to the buyer.

Naked short selling can have a number of negative effects on the market, particularly when the fails to deliver persist for an extended period of time and result in a significantly large unfulfilled delivery obligation at the clearing agency where trades are settled. At times, the amount of fails to deliver may be greater than the total public float. In effect the naked short seller unilaterally converts a securities contract (which should settle in three days after the trade date) into an undated futures-type contract, which the buyer might not have agreed to or that would have been priced differently. The seller's failure to deliver securities may also adversely affect certain rights of the buyer, such as the right to vote. More significantly, naked short sellers enjoy greater leverage than if they were required to borrow securities and deliver within a reasonable time period, and they may use this additional leverage to engage in trading activities that deliberately depress the price of a security.
