Shares of multi-level marketers Herbalife (HLF) and Nu Skin (NUS) are sliding after the Federal Trade Commission said on its website that it will co-host a press conference in Lexington, KY, today at 1 p.m. ET with the Kentucky Attorney General's office, to announce a "major action against an allegedly illegal pyramid scheme." Investor Bill Ackman attributed his well-publicized short position in Herbalife to the idea that the company is a pyramid scheme. However, neither Herbalife nor Nu Skin is mentioned in the FTC's announcement nor is either company headquartered in Kentucky. In 2010, USA Today said Kentucky Attorney General Jack Conway's office was investigating multi-level marketing company Fortune Hi-Tech, citing former managers of the company. Conway's office did not confirm or deny an investigation into Fortune Hi-Tech, the report noted, but did say Fortune could violate Kentucky's anti-pyramid scheme law if product sales alone couldn't "sustain the people at the lower end of the chain." The Fly notes that Fortune Hi-Tech has its headquarters in Lexington, KY, according to the company's corporate website. In late morning trading, shares of Herbalife are down $2.74, or 6.29%, to $40.85, while Nu Skin is down $1.75, or 3.88%, to $43.33.
