The Big Short_ Inside the Doomsday Machine - Michael Lewis [60]
Charlie and Jamie preferred Ben to keep his apocalyptic talk to himself. It made people uncomfortable. There was no reason anyone needed to know, for example, that Ben had bought a small farm in the country, north of San Francisco, in a remote place without road access, planted with fruit and vegetables sufficient to feed his family, on the off chance of the end of the world as we know it. It was hard for Ben to keep his worldview to himself, however, especially since it was the first cousin of their investment strategy: The possibility of accident and disaster was just never very far from their conversations. One day on the phone with Ben, Charlie said, You hate taking even remote risks, but you live in a house on top of a mountain that's on a fault line, in a housing market that's at an all-time high. "He just said, 'I gotta go,' and hung up," recalled Charlie. "We had trouble getting hold of him for, like, two months."
"I got off the phone," said Ben, "and I realized, I have to sell my house. Right now." His house was worth a million dollars and maybe more yet would rent for no more than $2,500 a month. "It was trading more than thirty times gross rental," said Ben. "The rule of thumb is that you buy at ten and sell at twenty." In October 2005 he moved his family into a rental unit, away from the fault.
Ben thought of Charlie and Jamie less as professional money managers than as dilettantes or, as he put it, "a couple of smart guys just punting around in the markets." But their strategy of buying cheap tickets to some hoped-for financial drama resonated with him. It was hardly foolproof; indeed, it was almost certain to fail more often than it succeeded. Sometimes the hoped-for drama never occurred; sometimes they actually didn't know what they were doing. Once, Charlie found what he thought was a strange price discrepancy in the market for gasoline futures, and quickly bought one gas contract, sold another, and made what he took to be a riskless profit--only to discover, as Jamie put it, "one was unleaded gasoline and the other was, like, diesel." Another time, the premise was right but the conclusion was wrong. "One day Ben calls me and says, 'Dude, I think there's going to be a coup in Thailand,'" said Jamie. There'd been nothing in the newspapers about a coup in Thailand; this was a genuine scoop. "I said, 'C'mon, Ben, you're crazy, there's not going to be a coup. Anyway, how would you even know? You're in Berkeley!'" Ben swore he had talked to a guy he used to work with in Singapore, who had his finger on the pulse in Thailand. He was so insistent that they went into the Thai currency market and bought what appeared to be stunningly cheap three-month puts (options to sell) on the Thai baht. One week later, the Thai military overthrew the elected prime minister. The Thai baht didn't budge. "We predicted a coup, and we lost money," said Jamie.
The losses, by design, were no big deal; the losses were part of the plan. They had more losers than winners, but their losses, the cost of the options, had been trivial compared to their gains. There was a possible explanation for their success, which Charlie and Jamie had only intuited but which Ben, who had priced options for a big Wall Street firm, came ready to explain: Financial options were systematically mispriced. The market often underestimated the likelihood of extreme moves in prices. The options market also tended to presuppose that the distant future would look more like the present than it usually did. Finally, the price of an option was a function of the volatility of the underlying stock or currency or commodity, and the options market tended to rely on the recent past to determine how volatile a stock or currency or commodity might be. When IBM stock was trading at $34 a share and had been hopping around madly for the past year, an option to buy it for $35 a
