The other monumental loser today was NuSkin (NUS), which tumbled 26 percent. China, which accounts for about half of the company's sales, is investigating whether it operates as a pyramid scheme.
Herbalife (HLF), which has faced down similar charges of being a pyramid operation recently, lost 10 percent, even though its exposure to the Chinese market is not as large.
On the earnings front, UnitedHealth Group (UNH) lost nearly 3 percent, even though earnings topped expectations and enrollments jumped.
In the financial sector, Goldman Sachs (GS) fell 2 percent as earnings fell. Citigroup (C) lost more than 4 percent on weaker than expected results. But Blackrock (BLK), the largest provider of ETFs, gained 1.5 percent. Its net rose and the company hiked its dividend.
The railroad giant CSX (CSX) derailed, losing more than 6 percent as net fell due to lower coal shipments. That dragged down other rail stocks. Norfolk Southern (NSC) fell 4 percent.
In the online world, AOL (AOL) jumped 11 percent after agreeing to spin off and sell a majority stake in its local news network, Patch. (A disclaimer: AOL produces this report.) But Yahoo (YHOO) fell 2 percent after CEO Marissa Mayer fired the chief operating officer just a year after she hired him. And LinkedIn gained 7 percent, after it hired a respected Chinese executive to run its operations in China.
Finally, there's a new clown in charge at the parent company of Chuck E. Cheese. The restaurant/entertainment chain CEC (CEC) gained 13 percent after agreeing to be acquired by Apollo Group.
