That depends on how much insider trading they are willing to do. How much advance notice will they give me about the apocalypse before it goes public?
Keep in mind no one could know that they knew. You could not tell your family or friends or anyone. They have been working very hard to look hapless so when the big one hits they will not appear to have any foreknowledge.
I don't see them telling you though. Not until after the PAW when the SEC Harvard MBAs guys are all hitched to a plow trying to grow corn for the local warlord instead of pretending to enforce laws. Because then the laws won't matter.
