NASDAQ OMX Announces Intent to Modify Existing Rules on "Stub" Quotes

The NASDAQ OMX Group (Nasdaq:NDAQ) today announced that it intends to propose detailed rules to modify existing rules surrounding "stub" quotes within the Nasdaq Stock Market's market-maker and select market-maker programs to more effectively serve market participants, investors and listed companies. The decision is in response to some of the market events that occurred on May 6th that led to the use of "stub" quotes being executed against due to liquidity that was absorbed by selling pressure.

NASDAQ OMX also took the lead this week by announcing the NASDAQ Volatility Guard focused on safeguarding investors during times of high trading stress and remains committed to working with the Commission on protecting investors.
