Shares Of Nu Skin And Herbalife Are On A Major Tear

Shares of NuSkin are going nuts today following a more than $500,000 fine from a Chinese regulator.

The stock was last trading up more than 26% at about $94 a share.

Back in January, NuSkin's stock plummeted after China's State Administration for Industry & Commerce (SAIC) said it would investigate following a report in "The People's Daily" in China that criticized NuSkin's marketing practices and alleged that it's a pyramid scheme.

NuSkin is a multi-level marketing company that sells anti-aging products. Chinese direct selling laws are very strict.

Today, China's SAIC fined the company $540,000 for misleading consumers and illegal sales, Reuters reported.

Meanwhile, Herbalife, another multi-level marketing company that sells weight loss products, is trading higher this morning. The stock was last trading up more than 6%.

Hedge fund manager Bill Ackman, who is famous for his Herbalife short, has accused the company of violating Chinese direct-selling laws. He believes the company operates as a "pyramid scheme."

Earlier this month, it was revealed that Herbalife is being investigated by the Federal Trade Commission. Since then, Herbalife's stock has declined.
