From at least June 2009 through December of that year, Athena placed large
transactions for stocks in the final two seconds of Nasdaq Stock Market
trading, right before 4 p.m. New York time, driving prices “slightly higher
or lower,” according to the SEC. “The manipulated closing prices allowed
Athena to reap more reliable profits from its otherwise risky strategies.”
Athena Capital Research LLC used $40 million to rig prices of thousands of
stocks including EBay Inc. (EBAY) for at least six months in 2009, U.S.
regulators said today when fining the high-speed trading firm $1 million.
Using a system dubbed “Gravy,” Athena manipulated shares of Nasdaq-listed
stocks, undermining the exchange operator’s end-of-day procedures for
reducing price volatility, according to the Securities and Exchange
Commission. With “high-powered computers, complex algorithms and rapid-fire
trades,” the New York-based firm tainted closing prices used by fund
managers to track their performance, the SEC said.
