Dividend Trade Activity

Our market share statistics continue to be negatively impacted by trading activity related to dividend trades among certain options market makers. These trades temporarily inflate and distort trading volume and market share when transacted. If the volume from the largest dividend trades were excluded from the data, our market share of equity options for the month of April would increase to 30.7% from 30.2%, an increase of 0.5 market share points.

On a year-to-date basis, our market share would increase to 31.3% from 30.2%, an increase of 1.1 market share points, if the volume from the largest dividend trades were excluded. The exclusion of dividend trades from total industry volume data presents a more relevant measure of the relative trends in our business.
