Summary
Stefan Lumiere, a 46-year-old former portfolio manager at Visium Asset Management, stood trial in federal court in Manhattan on January 11, 2017, on charges of defrauding investors through securities valuation manipulation. Lumiere, who served as the brother-in-law of Visium founder Jacob Gottlieb, managed the Visium Credit Opportunities Fund from May 2009 to April 2013 and faced accusations that he systematically mismarked asset values during the 2011 to 2013 period.
According to prosecutors, Lumiere conspired with fellow portfolio manager Christopher Plaford to deceive investors by corruptly inflating the value of distressed-debt securities held in the fund, which specialized in healthcare industry debt instruments. The scheme involved obtaining what prosecutors characterized as "sham quotes" from brokers who provided artificially elevated valuations on demand. Assistant U.S. Attorney Damian Williams told jurors that this valuation fraud enabled Visium to collect millions of dollars in performance fees based on false asset values, directly enriching the firm at investors' expense.
The trial emerged from a broader federal investigation into Visium that precipitated the $8 billion asset manager's wind-down and resulted in criminal charges against multiple executives. The probe also ensnared Sanjay Valvani, a portfolio manager who committed suicide in June 2016 following accusations of insider trading, highlighting the severity of misconduct uncovered at the firm.
Defense attorney Eric Creizman argued that Lumiere maintained his innocence and acted in good faith when valuing securities. Creizman urged jurors to scrutinize testimony from two cooperating former Visium employees and contended that Lumiere's valuation methodology was grounded in legitimate market data rather than arbitrary pricing. "This is not picking a price out of the air," Creizman stated, arguing the valuations were supported by substantive analysis.
The case represents a significant enforcement action against portfolio-level misconduct at a major hedge fund, addressing how valuation discretion in fixed-income and distressed-debt strategies can be weaponized to manipulate reported performance and investor returns.
