NEW YORK, June 4 The New York Attorney General's
sweeping investigation into the U.S. stock market will include
whether trading centers known as "dark pools" are conducting
themselves properly, an official said on Wednesday.
New York Attorney General Eric Schneiderman is seeking
information from exchanges and alternative trading platforms
about their relationships with high-frequency trading firms, as
part of its probe into allegedly unfair trading practices on
Wall Street, sources have previously told Reuters.
Broker-run trading systems known as dark pools, where
participants are anonymous and trading information is hidden
until after the trades are completed, are a key focus, said Chad
Johnson, head of the agency's Investor Protection Bureau.
"We remain highly interested in this area," he said at a
conference held by Sandler O'Neill and Partners.
He said his office is looking into whether dark pools are
operating in a way that is consistent with how they market
themselves, that they have the interests of investors in mind,
and that brokers directing trades to their own dark pools do so
in a way that does not present conflicts of interest.
Dark pools are more lightly regulated than stock exchanges
and do not have to make information on how they operate public.
Several dark pools, including those run by IEX Group,
Investment Technology Group Inc, Credit Suisse Group AG
, and Goldman Sachs Group Inc, have recently
made their rules public. Johnson said that was a step in the
right direction in increasing market transparency.
"Frankly, it's about time that this trend has started to
take hold," he said. He added, however, that of the over 40 U.S.
dark pools, only a small minority have made their rules public,
and that there are practices not included in those rules that
his office is looking into.
"That doesn't end our interest in the area, by any means."
