On September 7, the New York Stock Exchange announced that it will halt trading in any security that may fall below $1.05, which will result in the publication of an automated trade halt message to all NYSE Alert subscribers. The NYSE’s alert system is a push system that publishes regular ongoing alerts on various issues, and automatically sends notice of those alerts to subscribers. The message for a trading halt is classified as Message Type 131 – Opening Delays and Trading Halts. In contrast to other trading halts described in NYSE Rule 123D, a “Sub-penny Trading” halt is automatic and does not require the approval of any NYSE floor officials.
