In many cases, these folk can't justify selling these guns because the guns are worth so much less today than what they paid a year ago
And hence the REAL issue... they KEY to any financial planning is knowing when to buy and when to sell. Of course nobody REALLY knows... but people make edcuated guesses. For instance, most people on this board could have told you that after Obama was elected, it was too late to get a good deal on a firearm; you needed to wait a year or two for prices to come back down to earth. Well, to nobody's surprise here, two things happened: 1) people who waited panicked and overpaid by buying literally at the top where sellers were naming their price and 2) people who overpaid and could no longer justify owning the firearm (loss of job, didn't use it, etc.) sold at heavy losses, and have flooded the market. In investing this is called a bubble or a spike.
Had ANY of us liquidated our gun collections in January of 2009, all of us would have made HUGE profits.
We watched the same thing when stocks were overbought during the internet bubble. I was a stockbroker at the time and literally had clients paying hundreds of dollers PER SHARE for shares of companies that never produced any product and no longer exist just 10 years later! Ask yourself "Why". Many of these companies didn't produce a single thing and vanished overnight.
We watched the same thing during the housing market boom of the 1990s and early 2000s... Buyers were chasing prices through the roof (literally) and sellers were naming their prices. Loans were easy to get and people were signing on the dotted line for any price. And then the bottom fell out. Why were houses doubling in price every 5 years?
We are currently watching college educations going the same route. For the first time in history it was reported that a college degree may not be a wise investment at going prices because they are too expensive, but loans were easy to get.
And GUESS WHAT ELSE is overbought.... look at the charts on gold. Straight up.
But ask yourself "Why"... What makes gold so precious? Nobody has ever been able to tell me other than, just because. Electronics conductors? Please. Jewelry? Who cares?
I think gold is a suckers market. The Sheeple are being taking to the slaughter. $1300 for an ounce of colorful metal. Foolishness.
To answer the OP question - I DO think that firearms AND ammo are a good investment for a WELL DIVERSIFIED investment class. Like any investment, you MUST buy low. That means that retail is strictly out. It means buying privately, new or near new guns for 20% below retail. Buy your ammo in bulk on sale. Know your guns and ammo. Store them well. Best case you can sell them during a perceived crisis at a large profit, or one of your guns becomes valuable unexpectedly (the K31 has doubled in price in 3 years). Worst reasonable case is that you either break even or, if prices fall through the floor, you have a functioning firearm and ammo - assets to show for it under any conditions.
Other good investments are mutual funds (however I personally think the stock market is rigged, and usually individual stocks are a bad bet, but with mutual funds you spread that risk).
