"TV: Radiation levels nearly doubled in Fukushima soil sample over 5-month period"
Meaning? They lost Japan. The place is uninhabitable. This is the only crisis that gets worse with time. They are killing everyone slowly.
"Quantifying risks" with regards to MPT involves beta, and enough studies have shown that low beta stocks outperform high beta stocks, which is the opposite of what's supposed to happen. You stick to MPT, I'll tough it out with Keynes, Graham, and Dodd.
Tokyo Electric is actually my biggest holding. As Peter Lynch says, distressed nukes make the best investments. As Graham and Dodd said, well capitalized utilities rarely go into bankruptcy. Buy when the dividends omitted, sell once it's reinstated.
Graham and Dodd were dealing with U.S. utility stocks not overseas utilities. Big difference when forced into quantifying political, legal, liquidity, repatriation, and currency risk. It's a different ballgame than Graham and Dodd's racket.
