Hewlett-Packard remains a company "under assault," argued hedge fund short-seller Jim Chanos Thursday, saying that's why he's still betting against CEO Meg Whitman's turnaround of the tech giant.
"Whitman seems to be a lot more optimistic than we are," Chanos, founder and president of Kynikos Associates, said on CNBC's "Squawk Box." His hedge fund has $5 billion in assets of management.
HP, which was kicked out of the Dow Jones Industrial Average last month, saw its stock increase nine percent Wednesday, after Whitman said she expects the year-over-year revenue decline in fiscal 2014 to moderate with "pockets of growth" before business accelerates again in 2015.
Chanos read her comments differently: "They are now talking about revenue declines in 2014. That's not what they were saying before. In effect, the guidance keeps coming down at that company."
