I found that investing in BP when people were at their most pessimistic about the well being capped did work well.

Unfortunately, following up that success by buying into TEPCO once it had dropped by half after their accident turned out not to be a good move.

However, one may console oneself that it was a public service in providing some cash to the Japanese pension funds, proverbial widows and orphans and whatnot that were selling at that time.
