SEC Commissioner Elad L. Roisman and SEC Division of Trading and
Markets Director Brett Redfearn raised various questions and
concerns relating to current market data products, market access
services and related fees.
At the SEC Staff Roundtable on Market Data and Market Access,
Mr. Redfearn described the means by which market data is
distributed and the costs associated with obtaining such data. He
explained that the SEC divides market data into two types: (i)
"core" market data consolidated through a central
information processor called the "SIP," and (ii)
proprietary data that is sold by the individual exchanges, the
price of which is generally set by the exchanges. Mr. Redfearn
described the proprietary data as "faster, more content-rich
and more costly" than core data. He expressed concern that
market participants might not find core data sufficient and, thus,
would be required to purchase proprietary data over which
individual exchanges might have monopoly
