What assets would be valuable in a post-apocalyptic scenario?
This is going to be a list of some things that will likely be of value immediately after some apocalyptic event.  However, note that I am not answering your question of what you should invest in now to take advantage of such an event.  That is a pretty ridiculous notion.  Preparing oneself for such a possibility is certainly a good idea.  That said, there are some realistic limitations to how you could take advantage of such a situation.  Namely, the very real requirement of physical security.  Unless you have a huge posse -- armed to the teeth -- to defend your cache, someone will come along with a bigger and better armed group to take it.  (Not to mention that I am the type of person that would -- at least -- consider organizing such a group to take you down; if only as a matter of principle.) Guns & ammo (Also, knives; ideally ones that can be used as weapons and for food preparation/hunting.) Alcohol.  Especially liquor.  It's concentrated and easier to store than beer or wine.  Beside for getting inebriated, it is useful as a sedative and antiseptic. Non-perishable foods.  Canned goods are obvious.  Though, grains and cereals can be stored with relative ease under some circumstances.  (Obviously, not so easily done in an urban area.) Methods of starting a fire.  Preferably rugged ones, such as flint and steel.  (Lighters would only be of limited use.  Matches are bulky and require water-tight storage.) Salt and/or salt-licks.  (Possibly, other forms of non-perishable bait.)  As bstpierre puts it, hunting will be about survival not sport. Hand-tools. Textiles, fabrics, thread and needles. Medicines of all sorts, though especially antibiotics, antiseptics and painkillers. Books of a practical nature.  Topics such as: wilderness survival, cooking, carpentry, etc. The list is mostly ordered in terms of value & practicality. Ultimately, I doubt there is much that will provide a practical investment idea for such a scenario.  The physical security issue is a big limiting factor.  In a post-apocalyptic scenario it goes back to who is bigger, stronger and better armed. One thing does come to mind: knowledge.  Prepare yourself with the skills and knowledge you need to survive in such a scenario and you will be invaluable.  Also, as bstpierre notes in the comments, connections will likely also be important.  (Probably local or nearby connections.)  No one person can do it all alone.  It will come down to cooperation.
