Short-seller maven James Chanos of Kynikos Associates, who last year called Hewlett-Packard Co. “the ultimate value trap for investors,” says he is still shorting the computer maker — as well as Dell. Speaking at length on CNBC, the hedge fund manager who oversees roughly $6 billion of assets, once again proclaimed that the personal computer business “is falling apart.” Chanos says he actually got out of Dell last year but began shorting it again this year when founder Michael Dell announced plans to take the company private. “I’m puzzled, as a financial analyst and a business analyst, why this is an attractive deal,” Chanos says, adding, that cash flow “is plummeting.” Chanos acknowledges having a small long position on Apple, which he says he has never shorted. What about nutrition-supplements purveyor Herbalife? Chanos admits he was short Herbalife last year but covered in late December when the stock plunged, following William Ackman’s much-ballyhooed presentation on the company being a Ponzi scheme. The “multi-level marketing model is flawed,” Chanos says.

However, the investment bank retained its Outperform rating on the stock, saying that Apple will redistribute 25 percent of its market capitalization over the next three years and that it promises a dividend yield of 3 percent.
