Mathew Martoma, 39, was convicted in February of one count of conspiracy to commit securities fraud and two counts of securities fraud.
A former portfolio manager of CR Intrinsic Investors, a division of hedge fund giant SAC Capital, Martoma will be sentenced on September 8.
Manhattan's top federal prosecutor Bharara had argued earlier that Martoma should be sentenced to more than eight years in prison.
Bharara said while the USD 9.4 million forfeiture judgment exceeds Martoma's reported net worth of approximately USD 7.4 million, the forfeiture only requires him to return ill-gotten gains.

"...This is a serious offense -- the most lucrative inside trading offense ever proven -- and the penalties imposed by the Court should reflect that....Accordingly, the government respectfully requests that the Court impose a fine in addition to the forfeiture," Bharara said in the court papers.
The Probation Department has recommended a fine of USD 20,000.
In June, Bharara had asked the federal court to sentence Martoma to more than eight years in prison for collecting confidential information about a high-profile Alzheimer's disease drug trial and making profits and avoiding losses of USD 275 million for SAC Capital.
Martoma, a father of three, had earned the USD 9.4 million bonus for himself due to the various trades he did for SAC.
