  • In Head Trader Alert #2004-081, NASDAQ® announced that members would be required to begin using the .W modifier to identify Stop Stock Transactions in OTC Bulletin Board (OTCBB) and OTC Equity securities. The original effective date of this requirement was August 23, 2004.

    • NASDAQ expects these modifications to be complete in December 2004.
    • NASDAQ will issue an additional Head Trader Alert announcing the new compliance date.

OTCBB securities include national, regional, and foreign equity issues, warrants, units, ADRs, and Direct Participation Programs (DPPs).
