Subject: Rule Filing SR-NASD-98-21 Date: 4/2/98 1:03 PM In my opinion, the actual size rule should be adopted for the NASDAQ market. Increasingly, the NASDAQ is moving from a quote driven market to an order driven market with the new order handling rules. While minimum size may make some sense in a pure dealer market, we find 100 shares as the typical minimum in our order driven markets. Moving NASDAQ in that direction is sensible.
