Seventh person arrested in insider trading probe

It's yet another arrest of an expert consultant in the ever-widening FBI investigation into insider trading of tech companies.

The FBI has arrested another person in the ongoing investigation into the sharing of insider information with investors by consultants working for so-called expert firms.

The latest to be arrested is Winifred Jiau, 43, of Fremont, Calif. Like others charged or arrested on December 16, she has ties to Primary Global Research. She's accused of providing inside information to Primary Global clients who were portfolio managers at hedge funds of Nvidia and Marvell Technology during a period from 2006 to 2008. Prosecutors say she collected $200,000 during that time. She's facing charges of conspiracy and securities fraud.

In August of 2008, the complaint says, she provided managers of two hedge funds with detailed numbers for quarterly revenues, per-share earnings, and gross margins for the quarter ending that month. The complaint says that in the conversations she made it clear she had obtained the information directly from an employee of Marvell. The funds in question--they were not named in the complaint--allegedly made $820,000 on trades from the information.

On August 8, 2008, the complaint says, Jiau provided the hedge fund managers with an early look at Nvidia's quarterly revenue and told them it planned to announce a stock buyback, which it did four days later.

I've embedded the complaint below.
