Latest NYSE, Nasdaq Threshold Securities

The latest available lists of "threshold securities," compiled Tuesday by the New York Stock Exchange and the Nasdaq, reveal that a broad range of stocks across a number of industries have been subject to higher-than-normal trade-settlement failures.

Both markets began compiling the data after the implementation of Regulation SHO. The Securities and Exchange Commission created the rule with the intention of addressing persistent failures to deliver stock on trade-settlement dates and to target potentially abusive naked short-selling in equity securities.

Stocks are identified as threshold securities after five consecutive days of unusually high delivery failures. While the majority of trades settle on time, according to the SEC, Regulation SHO is meant for situations where the level of fails-to-deliver for a particular stock is so significant that it might affect the market for that security.

(The Web site of the Securities and Exchange Commission provides more detailed information on Regulation SHO.)
