Two years ago, I might have suggested the Trekkie Monster portfolio, but even that sucks right now. Blasted Facebook. :P

I would say diversify. Military and security stocks, not sure if any of the big property management companies are traded but they aren't a horrible idea. Small scale solar and wind power manufacturers. Water futures if they are being traded yet, but I haven't heard anything. Maybe national and municipal bonds, but don't be afraid to shop outside of the US.

For something more concrete, maybe part of a graveyard or mortuary.
