Although this strategy may prove to be a self-fulfilling prophecy, driving down values as other investors take the same defensive moves, it's better than the alternative—being the last one to remove risk, Dubin said. But his $2.2 billion hedge fund, owned by JPMorgan , will not short any assets.
Dubin said he's been "shocked" by the environment in 2010, explaining that he expected to be able to extract returns after two volatile years. He said he had felt "reasonably confident" the global economy was on its way up, with the US and China seeing growth.
"Then, of course, the sovereign debt crisis hit a wall and all bets are off," he said.
The most recent global action to shake his confidence was Germany placing curbs on naked short selling. He equated the move to the United States' emergency ban on short-selling in 2008, which "sucked confidence out of the market," he said.
As for the US, Dubin added that the financial reform bill has also caused concern, as investors aren't yet sure what implications it will have.
"The market hates uncertainty," he said.
