Robert Khuzami, director of enforcement at the Securities and Exchange Commission, said the charges show Rajaratnam's "secret of success was not genius trading strategies."
"He is not the master of the universe. He is a master of the Rolodex," Khuzami said.
Rajaratnam, 52, was ranked No. 559 by Forbes magazine this year among the world's wealthiest billionaires, with a $1.3 billion net worth.
Also charged in the scheme are Rajiv Goel, 51, of Los Altos, California, a director of strategic investments at Intel Capital, the investment arm of Intel Corp., Anil Kumar, 51, of Santa Clara, California, a director at McKinsey & Co. Inc., a global management consulting firm, and Robert Moffat, 53, of Ridgefield, Connecticut, senior vice president and group executive at International Business Machines Corp.'s Systems and Technology Group.
The others charged in the case were identified as Danielle Chiesi, 43, and Mark Kurland, 60, both of New York City.
