PRESS RELEASE: Instinet Continues Volume Growth Momentum in August

Agency-only broker’s US equities ADV surges to 431M shares, US listed-options ADV to 363K contracts.

NEW YORK – September 12, 2011 – Instinet Incorporated, a global leader in electronic trading and agency-only brokerage services, today announced that its US broker-dealer subsidiary, Instinet, LLC, saw its US equities ADV (average daily volume) reach 431M shares (4.09 percent overall market share*) in August, a 43 percent increase over July. For US-listed options, the firm’s ADV grew to 363K contracts (1.54 percent overall market share), which included a firm-record 613K contracts executed on August 8.

In addition, the firm continued its strong performance in both the NYSE and NASDAQ league tables, ranking in the top seven for NYSE agency program trading volume in each of the month’s five weeks and securing the sixth-ranked liquidity provider position for NASDAQ-listed securities traded on NASDAQ.

“In August we continued to see strong growth in both US equities and options volumes,” said Jonathan Kellner, President of the Americas at Instinet. “While volumes were up Street-wide, we were particularly pleased to see our core institutional flow surge to the extent that it did during the month, indicating that the buyside continues to look to Instinet as a safe harbor during periods of extreme volatility.”
