ISE's market share statistics continue to be negatively impacted by dividend trade strategies that are permitted based on a non-economic rationale, and inflate and distort trading volume and market share when transacted. Exclusion of dividend trades from total industry volume data presents a more relevant measure of the relative trends in our business.
