My favorite part: some guys from a hedge fund that's betting against subprime mortgages, at a subprime industry conference in late 2007: Their first stop was a speech given by the C.E.O. of Option One, the mortgage originator owned by H&R Block. When the guy got to the part of his speech about Option One’s subprime-loan portfolio, he claimed to be expecting a modest default rate of 5 percent. Eisman raised his hand. Moses and Daniel sank into their chairs. “It wasn’t a Q&A,” says Moses. “The guy was giving a speech. He sees Steve’s hand and says, ‘Yes?’” “Would you say that 5 percent is a probability or a possibility?” Eisman asked. A probability, said the C.E.O., and he continued his speech. Eisman had his hand up in the air again, waving it around. Oh, no, Moses thought. “The one thing Steve always says,” Daniel explains, “is you must assume they are lying to you. They will always lie to you.” Moses and Daniel both knew what Eisman thought of these subprime lenders but didn’t see the need for him to express it here in this manner. For Eisman wasn’t raising his hand to ask a question. He had his thumb and index finger in a big circle. He was using his fingers to speak on his behalf. Zero! they said. “Yes?” the C.E.O. said, obviously irritated. “Is that another question?” “No,” said Eisman. “It’s a zero. There is zero probability that your default rate will be 5 percent.” The losses on subprime loans would be much, much greater. Before the guy could reply, Eisman’s cell phone rang. Instead of shutting it off, Eisman reached into his pocket and answered it. “Excuse me,” he said, standing up. “But I need to take this call.” And with that, he walked out.
