The bankruptcy of Lehman Brothers (NYSE:LEH) is “quite favorable,” says Gloom, Boom & Doom Report publisher Marc Faber.

“The air will be clean within the next one month and we can get a fairly good rebound starting from the middle of October until the spring of next year,” he said in a Bloomberg Television interview.
