The bulls' time has run out as investors start to realize the global economy has a structural problem after bad news such as Societe Generale's profit warning and Friday's US jobs data, David Bloom, head of foreign exchange strategy at HSBC, told CNBC Wednesday.
"You get one bad unemployment number, you realize that the bears have massive ammunition. The bulls have nothing, they're naked," Bloom told European "Squawk Box."
In a surprise setback for the world's biggest economy, nonfarm payrolls dropped by 85,000 in December, a much bigger drop than analysts' expectations.
On Wednesday, Societe Generale sent a chill around markets when it warned it was expecting a "slight profit" for the fourth quarter of 2009, way below analysts' forecasts, because of new 1.4 billion-euro ($2.03 billion) writedowns from risky assets.
