Bill Ackman is taking a beating over the Herbalife ruling

Herbalife soars after dodging pyramid scheme tag in FTC settlement

Friday's ruling that Herbalife effectively is not a Ponzi scheme adds another layer to an already brutal year for hedge fund titan Bill Ackman.

The Pershing Square Capital chief has had a long-standing and very public short position on the dietary supplement company. He already had been sustaining major losses on the bet, but the Federal Trade Commission ruling is the sharpest blow yet. Though the commission found much fault with the way Herbalife operates, it stopped short of the "pyramid scheme" tag at Ackman has alleged in public statements and video presentations.

UPDATE: Despite the huge losses he has sustained on the bet against Herbalife, Ackman remained steadfast Friday after the ruling. He said the commission ruling puts intense pressure on the company to reform its practices, in particular a provision that distributors are only compensated for "profitable retail sales" and not for recruiting or buying products.

"In light of the fact that the FTC found that Herbalife distributors make little or no profit, or even lose money from retailing Herbalife products, there are no longer any meaningful incentives to become or remain an Herbalife distributor," Ackman said in a statement.

"We expect that once Herbalife's business restructuring is fully implemented, these fundamental structural changes will cause the pyramid to collapse as top distributors and others take their downlines elsewhere or otherwise quit the business," he added.

Ackman during a Thursday appearance on CNBC that the short position was costing him in the area of $20 million a year, but he remained confident.

"I think this is going to end up with the government suing Herbalife for being a pyramid scheme, or Herbalife capitulating and agreeing to changes, and in either circumstance the stock's not going to be $60 a share," he said on the brodcast. "While certainly we've been a patient investor here, I think this is the most attractive Herbalife has been from a risk-reward standpoint, and that's why we stayed short," he added.
