SIFMA provides comments to the Securities and Exchange Commission (SEC) on concerns that the 2018 NYSE and Cboe market data fee pricing publications are more examples of the exchanges’ unfettered and unwarranted price increase on proprietary exchange data. NYSE Arca proposes to increase the Non-Display Fee for the NYSE Arca Integrated feed by approximately 50% effective January 1, 2018. Unless the exchanges file the proposals soon, there will not be adequate time to review and respond to the proposals, nor does it provide the Commission staff with sufficient time to review the proposals and comments as required by the Exchange Act.
