Another One Bites The Dust In Insider Trading Investigation


New York, NY – Although many in the U.S. financial markets were on vacation last week, U.S. prosecutors continued to toil in its ongoing investigation into alleged insider trading.  On Wednesday, December 29, 2010 California technology industry executive, Winifred Jiau, was arrested on charges of leaking secrets about chipmakers Marvell Technology Group Ltd and Nvidia Corp to two hedge funds in exchange for illegal payments.

The Newest Charges

Based on recorded conversation, federal prosecutors charged Ms. Jiau with providing two hedge fund managers with information about Marvell’s financial results for the quarter ended May 3, 2008 – information which generated more than $820,000 in trading profits for these two separate funds.

The complaint also states that on Aug. 8, 2008, Ms. Jiau told the portfolio managers that Nvidia would post revenue of “892” for its 2009 fiscal second quarter and announce a stock buyback.  A few days later, Nvidia posted revenue of $892.7 million and added $1 billion to its buyback program, prosecutors said.

Prosecutors said that Ms. Jiau sold this information to the two hedge funds through an unnamed expert network in exchange for more than $200,000 of payments made through that firm.  While it is unclear which expert network paid Ms. Jiau, Primary Global Research said in a statement that it had used Jiau as a consultant from September 2006 to December 2008, when “the relationship was ended.”  This period roughly corresponds to the time frame that prosecutors said Jiau’s alleged illegal activity took place.

Jiau is the sixth person who has been arrested since U.S. authorities raided three hedge funds in November, 2010.  Jiau, age 43, was charged with one count of securities fraud and one count of conspiracy, and if convicted could face up to 25 years in prison and $5.25 million in fines.

The Upshot of This Arrest

Like most of the arrests seen so far in the ongoing federal investigation on insider trading, the charges against Ms. Jiau seem, on the surface, to be a “run of the mill” insider trading case as the information that was provided to the two unnamed hedge funds was both nonpublic information that was clearly material.

However, as we have said before, at least one of the arrests seems to indicate that the federal authorities could be trying to expand the definition of material nonpublic information as they try to alter the behavior of the hedge fund industry.

The Major Players in the Current Investigation
